-2001-11-21  Brian S. Dean  <bsd@bsdhome.com>
-
-	* avr.c, config_gram.y, lexer.l, term.c:
-	In interactive mode, reset the address and length if we start dumping
-	a memory type different than the previous one.
-
-	* avr.c, avrdude.conf.sample, config_gram.y:
-	Allow instruction data to be specified more flexibly, which can be
-	used to make the instruction input more readable in the config file.
-
-	* main.c: Bump version number.
-
-	* Makefile, avr.c, avr.h, avrdude.conf.sample, config.c, config.h:
-	* config_gram.y, fileio.c, fileio.h, lexer.l, main.c, term.c:
-	This is a major re-write of the programming algorithms.  The Atmel
-	serial programming instructions are not very orthoganal, i.e., the
-	"read fuse bits" instruction on an ATMega103 is an entirely different
-	opcode and data format from the _same_ instruction for an ATMega163!
-	Thus, it becomes impossible to have a single instruction encoding
-	(varying the data) across the chip lines.
-
-	This set of changes allows and requires instruction encodings to be
-	defined on a per-part basis within the configuration file.  Hopefully
-	I've defined the encoding scheme in a general enough way so it is
-	useful in describing the instruction formats for yet-to-be invented
-	Atmel chips.  I've tried hard to make it match very closely with the
-	specification in Atmel's data sheets for their parts.  It's a little
-	more verbose than what I initially hoped for, but I've tried to keep
-	it as concise as I could, while still remaining reasonably flexible.
-
-2001-11-19  Brian S. Dean  <bsd@bsdhome.com>
-
-	* avr.c, avr.h, avrdude.conf.sample, main.c, ppi.c, term.c:
-	Add support for ATMega163.
-
-	Add support for reading/writing ATMega163 lock and fuse bits.
-	Unfortunately, in looking at the specs for other ATMega parts, they
-	use entirely different instruction formats for these commands.  Thus,
-	these routines won't work for the ATMega103, for example.
-
-	Add support for sending raw command bytes via the interactive terminal
-	interface.  This allows one to execute any programming instruction on
-	the target device, whether or not avrprog supports it explicitly or
-	not.  Thus, one can use this feature to program fuse / lock bits, or
-	access any other feature of a current or future device that avrprog
-	does not know how to do.
-
-	Add in comments, an experimental instruction format in the
-	configuration file.  If this works out, it would allow supporting new
-	parts and non-orthoganal instructions across existing parts without
-	making avrprog code changes.

-	Hmmm ... cvs co -D <timestamp> does not work.  Change the revision

-
-	* avr.c, fileio.c, main.c, ppi.c, term.c:
-	Add a -V option to display the version information about each

-
-	Additionally, display a revision timestamp along with the version
-	number.  This also is intended for aiding in support and is the Unix
-	time of the latest component module.  Having this, should allow me to

-
-	* fileio.c:
-	Return the maximum address (+1) written as opposed to the actual

-	enable a buffer that can be used to isolate the target system from the
-	parallel port pins.  This is important when programming the target
-	in-system.
-
-	Totally change the way the pin definitions are defined.  Actually
-	set/clear pins based on the way more intuitive pin number, instead of
-	PPI data register, bit number combination.  A table of pin data is
-	used so that any hardware inversion done by the parallel port is
-	accounted for, what you set is actually what appears at the pin.
-	Retain the old method for handling Vcc, however, because the hold
-	method is much easier to use when setting / retrieving multiple pins
-	simultaneously.

-
-	* Makefile: Don't gzip the man page.
-
-	* avrdude.1: .Nm macro fix.  Submitted by Joerg.
-
-	* main.c: Cosmetic, don't output a preceding linefeed for usage().
-
-	* Makefile, avr.c, avr.h, fileio.c, term.c:
-	Makefile : use gzip -f for man page installation so that we don't get
-	           prompted.
-
-	avr.c avr.h fileio.c term.c :
-
-	     Change the avrpart data structure so that the typedef AVRMEM is
-	     used as an index into an array for the sizes of the memory types
-	     and also for pointers to buffers that represent the chip data for
-	     that memory type.  This removes a lot of conditional code of the
-	     form:
-
-			switch (memtype) {
-				case AVR_FLASH :
-			 	...
-			}
-
-	     Also, re-code avr_read_byte() and avr_write_byte() to properly
-	     handle the flash memory type without having to tell them whether
-	     they should program the high byte or the low byte - figure that
-	     out from the address itself.  For flash memory type, these
-	     routines now take the actual byte address instead of the word
-	     address.  This _greatly_ simplifies many otherwise simple
-	     operations, such a reading or writing a range of memory, by not
-	     having to worry about whether the address starts on an odd byte
-	     or an even byte.
-
-2001-01-20  Brian S. Dean  <bsd@bsdhome.com>
-
-	* avr.c, avr.h, fileio.c, fileio.h, main.c:
-	Return error codes instead of exiting, thus making sure that we exit
-	only via main() so that the exitspecs are properly applied.
-
-	When reading input data from a file, remember how many bytes were read
-	and write and verify only that many bytes.
-
-	Don't complain when an input file size is smaller than the memory size
-	we are programming.  This is normal.
-
-	* fileio.c:
-	Correct checksum calculation; failure to account for the value of the
-	record type was causing non-zero record types to be calculated
-	incorrectly.
-
-	* Makefile, main.c: Makefile : install the man page
-
-	main.c : drop the giant usage text now that we have a man page.
-
-	* avrdude.1:
-	Add initial man page graciously contributed by Joerg Wunsch.  Thanks
-	Joerg!
-
-2001-01-19  Brian S. Dean  <bsd@bsdhome.com>
-
-	* term.c:
-	Accept abbreviations for eeprom and flash for the dump and write
-	commands.
-
-	Fix small bug keeping 1 character command lines from being added to
-	the history.
-
-	* term.c:
-	Implement enough state in cmd_dump so that if it is called with no
-	arguments, it successively dumps the next chunk of data of the same
-	previously specified length.
-
-	* term.c, term.h, fileio.c, fileio.h, main.c, ppi.c, ppi.h:
-	* Makefile, avr.c, avr.h, avrprog.c:
-	The program was getting too large for a single file.  Split it up into
-	more modular pieces.
-
-	Also, accept command abbreviations as long as they are not ambiguous.
-
-	* avrprog.c:
-	Add ability to specify the state of the power and reset pins on
-	program exit.  Default to leaving the pins in the state they were when
-	we found them.

-
-	* Makefile, avrprog.c:
-	Switch to using readline() for getting terminal input.  I can't seem
-	to get the history capabilities working yet, but even so, it does
-	better handling of the prompt and strips newlines for us, so it's
-	still a win.
-
-	Add a few new commands for terminal mode: help, sig, part, erase.
-	Display rudimentory help using the help command.

-
-2001-01-14  Brian S. Dean  <bsd@bsdhome.com>
-
-	* avrprog.c: Free a buffer.
-
-	* avrprog.c:
-	Use a smarter programming algorithm - read the existing data byte
-	first and only write the new one if it is different.
-
-	Add -n option which is a test mode in which the chip is not actually
-	updated.  This option does not affect writes in interactive mode.
-
-	* avrprog.c: Add the "dump" and "write" interactive commands.
-
-	* avrprog.c:

-
-	Clean up debugging code a little, utilize fileio() instead of making
-	direct calls to b2ihex().
-
-	* avrprog.c: A lot of general code cleanup.
-
-	Re-work command line options to be more intuitive.
-
-	Support Intel Hex input and output file formats.  Provide hooks to

-
-	Add a few more part-specific parameters to the avrpart structure.
-
-	Only write the flash or eeprom if the data to be written is not 0xff.

-
-	* avr.c, avrdude.conf.sample, main.c, pgm.h, stk500.c:
-	The STK500 can perform paged read/write operations even on standard
-	"non-paged" parts.  Take advantage of that and use the faster internal

-
-	* avr.c, avr.h, avrpart.h, main.c, pgm.c, pgm.h, stk500.c:
-	Optimize reading and writing for the STK500 programmer if the part
-	supports paged reads and writes.  This greatly decreases the

-
-2002-11-23  Brian S. Dean  <bsd@bsdhome.com>

-	* CHANGELOG, main.c, term.c:
-	term.c - when in interactive terminal mode and dumping memory using
-	         the 'dump <memtype>' command without any address information,
-	         and the end of memory is reached, wrap back around to zero on
-	         the next invocation.
-
-	CHANGELOG - describe changes
-
-	main.c - update version number
-
-	* main.c:
-	When getting ready to initiate communications with the AVR device,
-	first pull /RESET low for a short period of time before enabling the
-	buffer chip.  This sequence allows the AVR to be reset before the
-	buffer is enabled to avoid a short period of time where the AVR may be
-	driving the programming lines at the same time the programmer tries
-	to.  Of course, if a buffer is being used, then the /RESET line from
-	the programmer needs to be directly connected to the AVR /RESET line
-	and not via the buffer chip.

-
-2007-01-11 Joerg Wunsch <j@uriah.heep.sax.de>

-	command (which is ignored by current AVR109 bootloaders),
-	send the first reply from the list of supported device
-	codes back rather than using avrdude.conf's idea about

-
-2010-01-12  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	Various fixes for Xmega devices.
-	* avrdude.conf.in: Correctly declare EEPROM page sizes for
-	all Xmega devices (0x20 instead of 0x100).
-	* avr.c: If a memory region has a page size declared, try
-	using the paged IO routines regardless of the target memory
-	name.  Xmega EEPROM requires to be written in paged mode.
-	Correctly use a long (rather than unsigned long) variable to
-	evaluate the success status of the paged mode write attempt.
-	* stk500v2.c: Don't apply TIF space offsets twice (bug #27995:
-	AVRDUDE 5.8svn fails to program and read XMEGA); use
-	stk500v2_loadaddr() prior to paged mode (EEPROM and flash) writes,
-	otherwise programming of flash areas will fail; while being there,
-	check the return value of stk500v2_loadaddr() everywhere; use the
-	correct write/erase mode bits (same as AVR Studio does).
-

-	* buspirate.c: Initialise firmware version to v0.0
-	prior to parsing the buspirate banner.
-
-2010-01-11  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	Clean-up the Xmega erase functions.
-	* jtagmkII_private.h: Add CMND_XMEGA_ERASE as well as
-	the various XMEGA_ERASE_* definitions (from updated
-	appnote AVR067)
-	* jtagmkII.c (jtagmkII_chip_erase): Correctly implement Xmega chip
-	erase based on CMND_XMEGA_ERASE.  After erasing an Xmega part, do
-	*not* reinitialize the world, as a subsequent programming
-	operation will fail (for unknown reasons).  Actually, this was
-	really only required for ancient AVRs, but doesn't hurt on mega
-	and tiny devices.
-	* jtagmkII.c (jtagmkII_pre_write): Remove, this turned out
-	to be just a chip erase.
-	* jtagmkII.c (jtagmkII_program_disable): Don't try reading
-	"hfuse" for Xmega parts; they don't have it.
-	* main.c (main): Re-enable auto-erase.  It's been done
-	before (as "jtagmkII_pre_write") in jtagmkII_paged_write()
-	anyway.  Xmega boot and application flash areas should be
-	handled separately in the future, so auto_erase can only
-	affect the area just being programmed.
-
-2010-01-11  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* main.c (main): disable safemode for Xmega parts.
-
-2010-01-12  Michal Ludvig  <mludvig@logix.net.nz>

-	has been called with the wrong pgm->cookie.  Wrap it
-	inside stk500v2_jtagmkII_close(), adjusting the cookie

-	for PPI_AVR_BUFF.
-
-2010-01-07  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	Submitted by Lukasz Goralczyk:
-	bug #27507: SIGSEGV when using avrdragon (avrdude 5.8)
-	* stk500v2.c (stk500v2_dragon_isp_initpgm): Use
-	stk500v2_jtagmkII_setup/stk500v2_jtagmkII_rather than their
-	jtagII counterparts, to get the private data properly
-	initialized.
-
-2010-01-07  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* buspirate.c: Cosmetics: remove UTF-8 dashes, adjust for 8-column

-2010-01-07  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-

-	* buspirate.h: add $ Id $ line.
-
-2010-01-07  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	Fix a few warnings that came up recently (some of them only triggered
-	by recent GCC versions).
-	* config_gram.y (parse_cmdbits): "brkt possibly used uninitialized"
-	(GCC errs here)
-	* jtagmkII.c (jtagmkII_reset32): "status possibly used uninitialized"
-	(I think GCC errs, too)
-	* buspirate.c: "pointers differ in signedness" (mismatch between

-	AVRDUDE API)
-
-2010-01-01  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

-
-	Mega-commit to bring in memory tagging.
-	Each memory image byte is now tagged as it's being read from a file.
-	Only bytes read from a file will be written or verified (modulo page
-	granularity requirements).
-	* avrpart.h: Add memory tags.
-	* avrpart.c: Allocate and initialize tag area.
-	* update.h: Drop unused parameter "verify" from do_op().
-	* pgm.h: Add parameter base_addr to the paged_load and paged_write
-	methods, respectively.
-	* avr.h: New parameter to avr_read: second AVRPART to verify against.
-	* fileio.c: Track all memory regions that have been read from an
-	input file by tagging them.
-	* update.c: Call avr_read() with the new parameter list.
-	* main.c: Call avr_initmem() to initialize the memory regions, rather
-	than trying to duplicate an unitialized part, and then let the
-	original part rot away.
-	* avr.c: Implement the heart of the new featureset.  For paged memory
-	areas, when writing or verifying, call the paged_write and paged_load
-	methods, respectively, once per page instead of on the entire memory.
-	When writing, only write bytes or pages that have content read from a
-	file.  Whe verifying, only read memory bytes or pages where the
-	verification data have been read from a file.  Only verify those bytes
-	that have been read from a file.

-
-	* configure.ac: In AC_CHECK_LIB for libftdi, check for

-	recent enough libftdi.

-	the is_at90s1200 configuration keyword.
-	* bitbang.c (bitbang_initialize): Replace existing test for
-	AT90S1200 by AVRPART_IS_AT90S1200
-	* avr.c (avr_write_byte_default): Avoid the pre-write reading for
-	the AT90S1200, as this appears to sometimes corrupt the high byte
-	by pre-programming the low byte just written into it.

-
-	* jtagmkII.c (jtagmkII_paged_load, jtagmkII_paged_write): fix bug
-	in memory type calculation for Xmega "boot" memory region.
-
-2012-04-25  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* update.c (parse_op): do not assume default memtype here
-	* main.c: after locating the part information, determine default
-	memtype for all update options that didn't have a memtype
-	specified; this is "application" for Xmega parts, and "flash" for
-	everything else.
-
-2012-04-24  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* fileio.c: Rework the way ELF file sections are considered: while
-	scanning the program header table, the offsets from a program
-	header entry must never be used directly when checking the bounds
-	of the current AVR memory region.  Instead, they must always be
-	checked based on the corresponding section's entry.  That way,
-	Xmega devices now properly take into account whether the segment
-	fits into any of the application/apptable/boot memory region.
-
-2012-04-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	bug #30756: When setting SUT to 64ms on XMEGA, avrdude doesn't

-	retry (up to twice) after some progressive delay.

-
-	* avrdude.conf.in (ATxmega16D4, ATxmega32D4, ATxmega64D4,

-	memory cell, move that one out from the generic .xmega part into
-	the individual Xmega A parts.

-	bug #29019: pagel/bs2 warning when uploading using stk500 to xmega
-	* stk500.c (stk500_initialize): Insert dummy values for PAGEL and

-	to proceed with the stk500_set_extended_parms() anyway.
-
-2012-04-19  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* stk500v2_private.h (struct pdata): add boot_start
-	* stk500v2.c: For the "flash" pseudo-memory of Xmega devices,
-	distinguish addresses between "application" and "boot" area.
-
-2012-04-18  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* fileio.c (elf2b): When checking the bounds of the current
-	program header segment, subtract `low' from ph[n].p_paddr in order
-	to correct the magic section offsets for the AVR's non-flash
-	memory regions.
-
-2012-04-18  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* fileio.c (elf_get_scn): Rather than trying to just match whether
-	any given section maps straight to a program header segment, use a
-	more sophisticated decision that matches any section as long as it
-	fits into the segment.  This is needed for situations where the
-	program header segment spans a larger area than the section data
-	provided.  (This can e.g. happen in an ELF file that contains no
-	data at address 0, like a bootloader only.)

-
-	bug #28744: Can't load bootloader to xmega128a1 (part 2, fix for
-	firmware >= V7.x)
-	* jtagmkII.c: Add firmware-version dependent handling of Xmega parameters.
-	V7.x firmware expects the NVM offsets being specified through the Xmega
-	parameters command, but left out as part of the memory address itself.
-	* jtagmkII_private.h: Add CMND_SET_XMEGA_PARAMS, and struct xmega_device_desc.

-	* jtagmkII_private.h: add MTYPE_BOOT_FLASH constant
-
-2012-03-30  Joerg Wunsch <j.gnu@uriah.heep.sax.de>

-
-	bug #30451: Accessing some Xmega memory sections gives not
-	supported error
-	* stk500v2.c: Handle all Xmega memory sections (except
-	"prodsig" which is not documented in AVR079)
-	* fileio.c: Treat the "boot", "application", and "apptable"

-
-2012-03-20  Joerg Wunsch <j.gnu@uriah.heep.sax.de>
-
-	* jtagmkII.c (jtagmkII_close): The GO command before signing off
-	turned out to be not required for normal megaAVR devices, and to
-	cause the exact opposite (i.e. the target stopping) on Xmega
-	devices being programmed to JTAG.  However, programming Xmega
-	devcies through PDI *does* need the GO command.

-2012-01-17  Rene Liebscher <R.Liebscher@gmx.de>
-
-	bug #34302: Feature request : device configuration with parent classes
-	* config_gram.y: if memory section is overwritten old entry is removed

-
-	* config_gram.y: Turn the usbpid parameter of the programmer into

+# AVRDUDE
+
+AVRDUDE - AVR Downloader Uploader - is a program for downloading and uploading
+the on-chip memories of Microchip’s [AVR microcontrollers](https://en.wikipedia.org/wiki/AVR_microcontrollers).
+It can program the Flash and EEPROM, and where supported by the programming
+protocol, it can program fuse and lock bits.
+AVRDUDE also supplies a direct instruction mode allowing one to issue any
+programming instruction to the AVR chip regardless of whether AVRDUDE
+implements that specific feature of a particular chip.
+
+AVRDUDE was originally written in 2003 by Brian S. Dean. Since 2006, AVRDUDE has been maintained by Jörg Wunsch,
+with the help of [various contributors](./AUTHORS).
+
+The latest version of AVRDUDE is always available here:\
+<https://github.com/avrdudes/avrdude>
+
+## Getting AVRDUDE for Windows
+
+To get AVRDUDE for Windows, install the latest version from the [Releases](http://download.savannah.gnu.org/releases/avrdude/) page.
+
+Alternatively, you may [build AVRDUDE](#building-avrdude-for-windows) yourself from source.
+
+## Getting AVRDUDE for Linux
+
+To install AVRDUDE for Linux, install the package `avrdude` by running the following commands:
+
+```console
+sudo apt-get install avrdude
+```
+
+Alternatively, you may [build AVRDUDE](#building-avrdude-for-linux) yourself from source.
+
+## Getting AVRDUDE for MacOS
+
+On MacOS, AVRDUDE can be installed through Mac Ports.
+
+Alternatively, you may [build AVRDUDE](#building-avrdude-for-macos) yourself from source.
+
+## Using AVRDUDE
+
+AVRDUDE is a command-line application. Run the command `avrdude` without any arguments for a list of options.
+
+A typical command to program your HEX file into your AVR microcontroller looks like this:
+
+```console
+avrdude -c <programmer> -p <part> -U flash:w:<file>:i
+```
+
+For instance, to program an **Arduino Uno** connected to the serial port **COM1** with a HEX file called `blink.hex`,
+you would run the following command:
+
+```console
+avrdude -c arduino -P COM1 -b 115200 -p atmega328p -D -U flash:w:objs/blink.hex:i
+```
+
+There are many different programmers and options that may be required for the programming to succeed.
+For more information, refer to the [AVRDUDE documentation](#todo).
+
+## General build instructions
+
+### Prerequisites
+
+Depending on your requirements, the following prerequisites are
+needed:
+
+* libelf including header files (for directly reading ELF files)
+* libusb 0.1 or 1.0 (or compatible), including header files
+* libftdi or libftdi1 (for direct access to FTDI devices)
+* libhidapi or libhid (for access to recent Atmel/Microchip dongles)
+
+### Building
+
+All source code is located in the `src/` subdirectory. Thus all
+instructions are relative to that directory.
+
+Source-code releases contain an up-to-date configure script that
+can be run to generate the required Makefiles:
+
+```console
+cd src && ./configure && make && sudo make install
+```
+At the end of the configure script, a configuration summary is issued,
+like this:
+
+```console
+Configuration summary:
+----------------------
+DO HAVE    libelf
+DO HAVE    libusb
+DO HAVE    libusb_1_0
+DO HAVE    libftdi1
+DON'T HAVE libftdi
+DON'T HAVE libhid
+DO HAVE    libhidapi
+DO HAVE    pthread
+DISABLED   doc
+DISABLED   parport
+DISABLED   linuxgpio
+DISABLED   linuxspi
+```
+
+Make sure all the features you are interested in have been found.
+
+Building the development source tree might possibly require to
+re-generate the configure script using the autoconf/automake
+tools. This can be done using the `bootstrap` script:
+
+```console
+cd src && ./bootstrap
+```

+.. index:: introduction
+
+AVRDUDE - AVR Downloader Uploader - is a program for downloading and
+uploading the on-chip memories of Atmel's AVR microcontrollers. It can
+program the Flash and EEPROM, and where supported by the serial
+programming protocol, it can program fuse and lock bits. AVRDUDE also
+supplies a direct instruction mode allowing one to issue any programming
+instruction to the AVR chip regardless of whether AVRDUDE implements
+that specific feature of a particular chip.
+
+AVRDUDE can be used effectively via the command line to read or write
+all chip memory types (eeprom, flash, fuse bits, lock bits, signature
+bytes) or via an interactive (terminal) mode. Using AVRDUDE from the
+command line works well for programming the entire memory of the chip
+from the contents of a file, while interactive mode is useful for
+exploring memory contents, modifying individual bytes of eeprom,
+programming fuse/lock bits, etc.
+
+AVRDUDE supports the following basic programmer types: Atmel's STK500,
+Atmel's AVRISP and AVRISP mkII devices,
+Atmel's STK600,
+Atmel's JTAG ICE (the original one, mkII, and 3, the latter two also in ISP mode), appnote
+avr910, appnote avr109 (including the AVR Butterfly),
+serial bit-bang adapters,
+and the PPI (parallel port interface). PPI represents a class
+of simple programmers where the programming lines are directly
+connected to the PC parallel port. Several pin configurations exist
+for several variations of the PPI programmers, and AVRDUDE can be
+configured to work with them by either specifying the appropriate
+programmer on the command line or by creating a new entry in its
+configuration file. All that's usually required for a new entry is to
+tell AVRDUDE which pins to use for each programming function.
+
+A number of equally simple bit-bang programming adapters that connect
+to a serial port are supported as well, among them the popular
+Ponyprog serial adapter, and the DASA and DASA3 adapters that used to
+be supported by uisp(1).  Note that these adapters are meant to be
+attached to a physical serial port.  Connecting to a serial port
+emulated on top of USB is likely to not work at all, or to work
+abysmally slow.
+
+If you happen to have a Linux system with at least 4 hardware GPIOs 
+available (like almost all embedded Linux boards) you can do without 
+any additional hardware - just connect them to the MOSI, MISO, RESET 
+and SCK pins on the AVR and use the linuxgpio programmer type. It bitbangs
+the lines using the Linux sysfs GPIO interface. Of course, care should
+be taken about voltage level compatibility. Also, although not strictly 
+required, it is strongly advisable to protect the GPIO pins from 
+overcurrent situations in some way. The simplest would be to just put
+some resistors in series or better yet use a 3-state buffer driver like
+the 74HC244. Have a look at http://kolev.info/avrdude-linuxgpio for a more
+detailed tutorial about using this programmer type.
+
+Under a Linux installation with direct access to the SPI bus and GPIO
+pins, such as would be found on a Raspberry Pi, the ``linuxspi``
+programmer type can be used to directly connect to and program a chip
+using the built in interfaces on the computer. The requirements to use
+this type are that an SPI interface is exposed along with one GPIO
+pin. The GPIO serves as the reset output since the Linux SPI drivers
+do not hold slave select down when a transfer is not occuring and thus
+it cannot be used as the reset pin. A readily available level
+translator should be used between the SPI bus/reset GPIO and the chip
+to avoid potentially damaging the computer's SPI controller in the
+event that the chip is running at 5V and the SPI runs at 3.3V. The
+GPIO chosen for reset can be configured in the avrdude configuration
+file using the `reset` entry under the linuxspi programmer, or
+directly in the port specification. An external pull-up resistor
+should be connected between the AVR's reset pin and Vcc. If Vcc is not
+the same as the SPI voltage, this should be done on the AVR side of
+the level translator to protect the hardware from damage.
+
+On a Raspberry Pi, header J8 provides access to the SPI and GPIO
+lines.
+
+Typically, pins 19, 21, and 23 are SPI MOSI, MISO, and SCK, while
+pins 24 and 26 would serve as CE outputs. So, close to these pins
+is pin 22 as GPIO25 which can be used as /RESET, and pin 25 can
+be used as GND.
+
+A typical programming cable would then look like:
+
+======== ========= ==================
+ J8 pin   ISP pin   Name             
+======== ========= ==================
+ 21       1         MISO             
+ -        2         Vcc - leave open 
+ 23       3         SCK              
+ 19       4         MOSI             
+ 22       5         /RESET           
+ 25       6         GND              
+======== ========= ==================
+
+(Mind the 3.3 V voltage level of the Raspberry Pi!)
+
+The `-P `portname`` option defaults to
+``/dev/spidev0.0:/dev/gpiochip0`` for this programmer.
+
+The STK500, JTAG ICE, avr910, and avr109/butterfly use the serial port to communicate with the PC.
+The STK600, JTAG ICE mkII/3, AVRISP mkII, USBasp, avrftdi (and derivatives), and USBtinyISP
+programmers communicate through the USB, using `libusb` as a
+platform abstraction layer.
+The avrftdi adds support for the FT2232C/D, FT2232H, and FT4232H devices. These all use 
+the MPSSE mode, which has a specific pin mapping. Bit 1 (the lsb of the byte in the config
+file) is SCK. Bit 2 is MOSI, and Bit 3 is MISO. Bit 4 usually reset. The 2232C/D parts
+are only supported on interface A, but the H parts can be either A or B (specified by the
+usbdev config parameter).
+The STK500, STK600, JTAG ICE, and avr910 contain on-board logic to control the programming of the target
+device.
+The avr109 bootloader implements a protocol similar to avr910, but is
+actually implemented in the boot area of the target's flash ROM, as
+opposed to being an external device.
+The fundamental difference between the two types lies in the
+protocol used to control the programmer. The avr910 protocol is very
+simplistic and can easily be used as the basis for a simple, home made
+programmer since the firmware is available online. On the other hand,
+the STK500 protocol is more robust and complicated and the firmware is
+not openly available.
+The JTAG ICE also uses a serial communication protocol which is similar
+to the STK500 firmware version 2 one.  However, as the JTAG ICE is
+intended to allow on-chip debugging as well as memory programming, the
+protocol is more sophisticated.
+(The JTAG ICE mkII protocol can also be run on top of USB.)
+Only the memory programming functionality of the JTAG ICE is supported
+by AVRDUDE.
+For the JTAG ICE mkII/3, JTAG, debugWire and ISP mode are supported, provided
+it has a firmware revision of at least 4.14 (decimal).
+See below for the limitations of debugWire.
+For ATxmega devices, the JTAG ICE mkII/3 is supported in PDI mode, provided it
+has a revision 1 hardware and firmware version of at least 5.37 (decimal).
+
+The Atmel-ICE (ARM/AVR) is supported (JTAG, PDI for Xmega, debugWIRE, ISP modes).
+
+Atmel's XplainedPro boards, using EDBG protocol (CMSIS-DAP compliant), are
+supported by the 'jtag3' programmer type.
+
+Atmel's XplainedMini boards, using mEDBG protocol, are also
+supported by the 'jtag3' programmer type.
+
+The AVR Dragon is supported in all modes (ISP, JTAG, PDI, HVSP, PP, debugWire).
+When used in JTAG and debugWire mode, the AVR Dragon behaves similar to a
+JTAG ICE mkII, so all device-specific comments for that device
+will apply as well.
+When used in ISP and PDI mode, the AVR Dragon behaves similar to an
+AVRISP mkII (or JTAG ICE mkII in ISP mode), so all device-specific
+comments will apply there.
+In particular, the Dragon starts out with a rather fast ISP clock
+frequency, so the `-B `bitclock``
+option might be required to achieve a stable ISP communication.
+For ATxmega devices, the AVR Dragon is supported in PDI mode, provided it
+has a firmware version of at least 6.11 (decimal).
+
+Wiring boards (e.g. Arduino Mega 2560 Rev3) are supported, utilizing
+STK500 V2.x protocol, but a simple DTR/RTS toggle to set the boards
+into programming mode.  The programmer type is 'wiring'. Note that
+the -D option will likely be required in this case, because the
+bootloader will rewrite the program memory, but no true chip erase can
+be performed.
+
+The Arduino (which is very similar to the STK500 1.x) is supported via
+its own programmer type specification 'arduino'.  This programmer works for
+the Arduino Uno Rev3.
+
+The BusPirate is a versatile tool that can also be used as an AVR programmer.
+A single BusPirate can be connected to up to 3 independent AVRs. See
+the section on
+*extended parameters*
+below for details.
+
+The USBasp ISP and USBtinyISP adapters are also supported, provided AVRDUDE
+has been compiled with libusb support.
+They both feature simple firmware-only USB implementations, running on
+an ATmega8 (or ATmega88), or ATtiny2313, respectively.
+
+The Atmel DFU bootloader is supported in both, FLIP protocol version 1
+(AT90USB* and ATmega*U* devices), as well as version 2 (Xmega devices).
+See below for some hints about FLIP version 1 protocol behaviour.
+
+The MPLAB(R) PICkit 4 and MPLAB(R) SNAP are supported in ISP, PDI and UPDI mode.
+The Curiosity Nano board is supported in UPDI mode. It is dubbed ``PICkit on
+Board'', thus the name `pkobn_updi`.
+
+SerialUPDI programmer implementation is based on Microchip's 
+*pymcuprog* (`https://github.com/microchip-pic-avr-tools/pymcuprog <https://github.com/microchip-pic-avr-tools/pymcuprog>`_) 
+utility, but it also contains some performance improvements included in
+Spence Kohde's *DxCore* Arduino core (`https://github.com/SpenceKonde/DxCore <https://github.com/SpenceKonde/DxCore>`_).
+In a nutshell, this programmer consists of simple USB->UART adapter, diode 
+and couple of resistors. It uses serial connection to provide UPDI interface. 
+:ref:`SerialUPDI_programmer` for more details and known issues.
+
+The jtag2updi programmer is supported,
+and can program AVRs with a UPDI interface.
+Jtag2updi is just a firmware that can be uploaded to an AVR,
+which enables it to interface with avrdude using the jtagice mkii protocol
+via a serial link (`https://github.com/ElTangas/jtag2updi <https://github.com/ElTangas/jtag2updi>`_).
+
+The Micronucleus bootloader is supported for both protocol version V1
+and V2. As the bootloader does not support reading from flash memory,
+use the `-V` option to prevent AVRDUDE from verifing the flash memory.
+See the section on *extended parameters*
+below for Micronucleus specific options.

+
+History and Credits
+===================
+
+AVRDUDE was written by Brian S. Dean under the name of AVRPROG to run on
+the FreeBSD Operating System.  Brian renamed the software to be called
+AVRDUDE when interest grew in a Windows port of the software so that the
+name did not conflict with AVRPROG.EXE which is the name of Atmel's
+Windows programming software.
+
+The AVRDUDE source now resides in the public CVS repository on
+savannah.gnu.org (`http://savannah.gnu.org/projects/avrdude/ <http://savannah.gnu.org/projects/avrdude/>`_),
+where it continues to be enhanced and ported to other systems.  In
+addition to FreeBSD, AVRDUDE now runs on Linux and Windows.  The
+developers behind the porting effort primarily were Ted Roth, Eric
+Weddington, and Joerg Wunsch.
+
+And in the spirit of many open source projects, this manual also draws
+on the work of others.  The initial revision was composed of parts of
+the original Unix manual page written by Joerg Wunsch, the original web
+site documentation by Brian Dean, and from the comments describing the
+fields in the AVRDUDE configuration file by Brian Dean.  The texi
+formatting was modeled after that of the Simulavr documentation by Ted
+Roth.

+***********************
+Terminal Mode Operation
+***********************
+
+AVRDUDE has an interactive mode called `terminal mode` that is
+enabled by the *-t* option.  This mode allows one to enter
+interactive commands to display and modify the various device memories,
+perform a chip erase, display the device signature bytes and part
+parameters, and to send raw programming commands.  Commands and
+parameters may be abbreviated to their shortest unambiguous form.
+Terminal mode also supports a command history so that previously entered
+commands can be recalled and edited.
+
+.. _Terminal_Mode_Commands:
+
+Terminal Mode Commands
+======================
+
+The following commands are implemented:
+
+
+
+*dump `memtype` `addr` `nbytes`*
+  Read `nbytes` from the specified memory area, and display them in
+  the usual hexadecimal and ASCII form.
+
+
+*dump*
+  Continue dumping the memory contents for another `nbytes` where the
+  previous dump command left off.
+
+
+*write `memtype` `addr` `byte1` ... `byteN`*
+  Manually program the respective memory cells, starting at address addr,
+  using the values `byte1` through `byteN`.  This feature is not
+  implemented for bank-addressed memories such as the flash memory of
+  ATMega devices.
+
+
+*erase*
+  Perform a chip erase.
+
+
+*send `b1` `b2` `b3` `b4`*
+  Send raw instruction codes to the AVR device.  If you need access to a
+  feature of an AVR part that is not directly supported by AVRDUDE, this
+  command allows you to use it, even though AVRDUDE does not implement the
+  command.   When using direct SPI mode, up to 3 bytes
+  can be omitted.
+
+
+*sig*
+  Display the device signature bytes.
+
+
+*spi*
+  Enter direct SPI mode.  The *pgmled* pin acts as slave select.
+  *Only supported on parallel bitbang programmers.*
+
+
+*part*
+  Display the current part settings and parameters.  Includes chip
+  specific information including all memory types supported by the
+  device, read/write timing, etc.
+
+
+*pgm*
+  Return to programming mode (from direct SPI mode).
+
+
+*verbose [`level`]*
+  Change (when `level` is provided), or display the verbosity
+  level.
+  The initial verbosity level is controlled by the number of `-v` options
+  given on the command line.
+
+
+*?*
+
+*help*
+  Give a short on-line summary of the available commands.
+
+
+*quit*
+  Leave terminal mode and thus AVRDUDE.
+
+
+In addition, the following commands are supported on the STK500
+and STK600 programmer:
+
+
+
+*vtarg `voltage`*
+  Set the target's supply voltage to `voltage` Volts.
+
+
+*varef [`channel`] `voltage`*
+  Set the adjustable voltage source to `voltage` Volts.
+  This voltage is normally used to drive the target's
+  *Aref* input on the STK500 and STK600.
+  The STK600 offers two reference voltages, which can be
+  selected by the optional parameter `channel` (either
+  0 or 1).
+
+
+*fosc `freq`[`M`|`k`]*
+  Set the master oscillator to `freq` Hz.
+  An optional trailing letter `M`
+  multiplies by 1E6, a trailing letter `k` by 1E3.
+
+
+*fosc off*
+  Turn the master oscillator off.
+
+
+*sck `period`*
+  *STK500 and STK600 only:*
+  Set the SCK clock period to `period` microseconds.
+
+  *JTAG ICE only:*
+  Set the JTAG ICE bit clock period to `period` microseconds.
+  Note that unlike STK500 settings, this setting will be reverted to
+  its default value (approximately 1 microsecond) when the programming
+  software signs off from the JTAG ICE.
+  This parameter can also be used on the JTAG ICE mkII/3 to specify the
+  ISP clock period when operating the ICE in ISP mode.
+
+
+*parms*
+  *STK500 and STK600 only:*
+  Display the current voltage and master oscillator parameters.
+
+  *JTAG ICE only:*
+  Display the current target supply voltage and JTAG bit clock rate/period.

+
+******************
+Configuration File
+******************
+
+AVRDUDE reads a configuration file upon startup which describes all of
+the parts and programmers that it knows about.  The advantage of this is
+that if you have a chip that is not currently supported by AVRDUDE, you
+can add it to the configuration file without waiting for a new release
+of AVRDUDE.  Likewise, if you have a parallel port programmer that is
+not supported by AVRDUDE, chances are good that you can copy and
+existing programmer definition, and with only a few changes, make your
+programmer work with AVRDUDE.
+
+AVRDUDE first looks for a system wide configuration file in a platform
+dependent location.  On Unix, this is usually
+`/usr/local/etc/avrdude.conf`, while on Windows it is usually in the
+same location as the executable file.  The name of this file can be
+changed using the *-C* command line option.  After the system wide
+configuration file is parsed, AVRDUDE looks for a per-user configuration
+file to augment or override the system wide defaults.  On Unix, the
+per-user file is `.avrduderc` within the user's home directory.  On
+Windows, this file is the `avrdude.rc` file located in the same
+directory as the executable.
+
+.. _AVRDUDE_Defaults:
+
+AVRDUDE Defaults
+================
+
+
+
+*default_parallel = "`default-parallel-device`";*
+  Assign the default parallel port device.  Can be overridden using the
+  *-P* option.
+
+
+*default_serial = "`default-serial-device`";*
+  Assign the default serial port device.  Can be overridden using the
+  *-P* option.
+
+
+*default_programmer = "`default-programmer-id`";*
+  Assign the default programmer id.  Can be overridden using the *-c*
+  option.

+
+*default_bitclock = "`default-bitclock`";*
+  Assign the default bitclock value.  Can be overridden using the *-B*
+  option.

+Programmer Definitions
+======================
+
+The format of the programmer definition is as follows:
+
+
+::
+
+  programmer
+      parent <id>                                 # <id> is a quoted string
+      id       = <id1> [, <id2> [, <id3>] ...] ;  # <idN> are quoted strings
+      desc     = <description> ;                  # quoted string
+      type     = "par" | "stk500" | ... ;         # programmer type (see below for a list)
+      baudrate = <num> ;                          # baudrate for serial ports
+      vcc      = <num1> [, <num2> ... ] ;         # pin number(s)
+      buff     = <num1> [, <num2> ... ] ;         # pin number(s)
+      reset    = <num> ;                          # pin number
+      sck      = <num> ;                          # pin number
+      mosi     = <num> ;                          # pin number
+      miso     = <num> ;                          # pin number
+      errled   = <num> ;                          # pin number
+      rdyled   = <num> ;                          # pin number
+      pgmled   = <num> ;                          # pin number
+      vfyled   = <num> ;                          # pin number
+      usbvid   = <hexnum>;                        # USB VID (Vendor ID)
+      usbpid   = <hexnum> [, <hexnum> ...];       # USB PID (Product ID)
+      usbdev   = <interface>;                     # USB interface or other device info 
+      usbvendor = <vendorname>;                   # USB Vendor Name
+      usbproduct = <productname>;                 # USB Product Name
+      usbsn    = <serialno>;                      # USB Serial Number
+    ;
+  
+
+If a parent is specified, all settings of it (except its ids) are used for the new 
+programmer. These values can be changed by new setting them for the new programmer.
+
+To invert a bit in the pin definitions, use `= ~ <num>`.
+
+Not all programmer types can handle a list of USB PIDs.

+
+Parent Part
+-----------
+
+Parts can also inherit parameters from previously defined parts
+using the following syntax. In this case specified integer and 
+string values override parameter values from the parent part. New 
+memory definitions are added to the definitions inherited from the 
+parent.
+
+
+::
+
+     part parent <id>                              # quoted string
+         id               = <id> ;                 # quoted string
+         <any set of other parameters from the list above>
+       ;
+  
+
+.. _Instruction_Format:
+
+Instruction Format
+------------------
+
+Instruction formats are specified as a comma separated list of string
+values containing information (bit specifiers) about each of the 32 bits
+of the instruction.  Bit specifiers may be one of the following formats:
+
+
+
+*1*
+  The bit is always set on input as well as output
+
+
+*0*
+  the bit is always clear on input as well as output
+
+
+*x*
+  the bit is ignored on input and output
+
+
+*a*
+  the bit is an address bit, the bit-number matches this bit specifier's
+  position within the current instruction byte
+
+
+*a`N`*
+  the bit is the `N`th address bit, bit-number = N, i.e., `a12`
+  is address bit 12 on input, `a0` is address bit 0.
+
+
+*i*
+  the bit is an input data bit
+
+
+*o*
+  the bit is an output data bit
+
+
+Each instruction must be composed of 32 bit specifiers.  The instruction
+specification closely follows the instruction data provided in Atmel's
+data sheets for their parts.  For example, the EEPROM read and write
+instruction for an AT90S2313 AVR part could be encoded as:
+
+
+::
+
+  read  = "1  0  1  0   0  0  0  0   x x x x  x x x x",
+          "x a6 a5 a4  a3 a2 a1 a0   o o o o  o o o o";
+
+  write = "1  1  0  0   0  0  0  0   x x x x  x x x x",
+          "x a6 a5 a4  a3 a2 a1 a0   i i i i  i i i i";
+
+  
+
+.. _Other_Notes:
+
+Other Notes
+===========
+
+
+* 
+  The `devicecode` parameter is the device code used by the STK500
+  and is obtained from the software section (`avr061.zip`) of
+  Atmel's AVR061 application note available from
+  `http://www.atmel.com/dyn/resources/prod_documents/doc2525.pdf <http://www.atmel.com/dyn/resources/prod_documents/doc2525.pdf>`_.
+
+* 
+  Not all memory types will implement all instructions.
+
+* 
+  AVR Fuse bits and Lock bits are implemented as a type of memory.
+
+* 
+  Example memory types are: `flash`, `eeprom`, `fuse`,
+  `lfuse` (low fuse), `hfuse` (high fuse), `efuse`
+  (extended fuse), `signature`, `calibration`, `lock`.
+
+* 
+  The memory type specified on the AVRDUDE command line must match one of
+  the memory types defined for the specified chip.
+
+* 
+  The `pwroff_after_write` flag causes AVRDUDE to attempt to power
+  the device off and back on after an unsuccessful write to the affected
+  memory area if VCC programmer pins are defined.  If VCC pins are not
+  defined for the programmer, a message indicating that the device needs a
+  power-cycle is printed out.  This flag was added to work around a
+  problem with the at90s4433/2333's; see the at90s4433 errata at:
+
+  `http://www.atmel.com/dyn/resources/prod_documents/doc1280.pdf <http://www.atmel.com/dyn/resources/prod_documents/doc1280.pdf>`_
+
+* 
+  The boot loader from application note AVR109 (and thus also the AVR
+  Butterfly) does not support writing of fuse bits.  Writing lock bits
+  is supported, but is restricted to the boot lock bits (BLBxx).  These
+  are restrictions imposed by the underlying SPM instruction that is used
+  to program the device from inside the boot loader.  Note that programming
+  the boot lock bits can result in a 'shoot-into-your-foot' scenario as
+  the only way to unprogram these bits is a chip erase, which will also
+  erase the boot loader code.
+
+  The boot loader implements the 'chip erase' function by erasing the
+  flash pages of the application section.
+
+  Reading fuse and lock bits is fully supported.
+
+  Note that due to the inability to write the fuse bits, the safemode
+  functionality does not make sense for these boot loaders.

+@end multitable
+
+Ensure the correct socket and routing card are mounted *before*
+powering on the STK600.  While the STK600 firmware ensures the socket
+and routing card mounted match each other (using a table stored
+internally in nonvolatile memory), it cannot handle the case where a
+wrong routing card is used, e. g. the routing card
+`STK600-RC040M-5` (which is meant for 40-pin DIP AVRs that have
+an ADC, with the power supply pins in the center of the package) was
+used but an ATmega8515 inserted (which uses the 'industry standard'
+pinout with Vcc and GND at opposite corners).
+
+Note that for devices that use the routing card `STK600-RC008T-2`,
+in order to use ISP mode, the jumper for `AREF0` must be removed
+as it would otherwise block one of the ISP signals.  High-voltage
+serial programming can be used even with that jumper installed.
+
+The ISP system of the STK600 contains a detection against shortcuts
+and other wiring errors.  AVRDUDE initiates a connection check before
+trying to enter ISP programming mode, and display the result if the
+target is not found ready to be ISP programmed.
+
+High-voltage programming requires the target voltage to be set to at
+least 4.5 V in order to work.  This can be done using
+*Terminal Mode*, see :ref:`Terminal_Mode_Operation`.
+
+.. _Atmel_DFU_bootloader_using_FLIP_version_1:
+
+Atmel DFU bootloader using FLIP version 1
+=========================================
+
+Bootloaders using the FLIP protocol version 1 experience some very
+specific behaviour.
+
+These bootloaders have no option to access memory areas other than
+Flash and EEPROM.
+
+When the bootloader is started, it enters a *security mode* where
+the only acceptable access is to query the device configuration
+parameters (which are used for the signature on AVR devices).  The
+only way to leave this mode is a *chip erase*.  As a chip erase
+is normally implied by the *-U* option when reprogramming the
+flash, this peculiarity might not be very obvious immediately.
+
+Sometimes, a bootloader with security mode already disabled seems to
+no longer respond with sensible configuration data, but only 0xFF for
+all queries.  As these queries are used to obtain the equivalent of a
+signature, AVRDUDE can only continue in that situation by forcing the
+signature check to be overridden with the *-F* option.
+
+A *chip erase* might leave the EEPROM unerased, at least on some
+versions of the bootloader.
+
+.. _SerialUPDI_programmer:
+
+SerialUPDI programmer
+=====================
+
+SerialUPDI programmer can be used for programming UPDI-only devices
+using very simple serial connection.
+You can read more about the details here 
+`https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md <https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md>`_
+
+SerialUPDI programmer has been tested using FT232RL USB->UART interface
+with the following connection layout (copied from Spence Kohde's page linked
+above):
+
+::
+
+  --------------------                                 To Target device
+                  DTR|                                  __________________
+                  Rx |--------------,------------------| UPDI---\\/\\/---------->
+    Tx---/\\/\\/\\---Tx |-------|<|---'          .--------| Gnd    470 ohm 
+      resistor    Vcc|---------------------------------| Vcc
+          1k      CTS|                     .`          |__________________
+                  Gnd|--------------------' 
+  --------------------
+  
+
+There are several limitations in current SerialUPDI/AVRDUDE integration,
+listed below.
+
+At the end of each run there are fuse values being presented to the user.
+For most of the UPDI-enabled devices these definitions (low fuse, high
+fuse, extended fuse) have no meaning whatsoever, as they have been 
+simply replaced by array of fuses: fuse0..9. Therefore you can simply
+ignore this particular line of AVRDUDE output.
+
+In connection to the above, *safemode* has no meaning in context
+of UPDI devices and should be ignored.
+
+Currently available devices support only UPDI NVM programming model 0 
+and 2, but there is also experimental implementation of model 3 - not
+yet tested.
+
+One of the core AVRDUDE features is verification of the connection by
+reading device signature prior to any operation, but this operation
+is not possible on UPDI locked devices. Therefore, to be able to 
+connect to such a device, you have to provide *-F* to override
+this check.
+
+Please note: using *-F* during write operation to locked device 
+will force chip erase. Use carefully.
+
+Another issue you might notice is slow performance of EEPROM writing
+using SerialUPDI for AVR Dx devices. This can be addressed by changing
+*avrdude.conf* section for this device - changing EEPROM page 
+size to 0x20 (instead of default 1), like so:
+
+::
+
+  #------------------------------------------------------------
+  # AVR128DB28
+  #------------------------------------------------------------
+
+  part parent    ".avrdx"
+      id        = "avr128db28";
+      desc      = "AVR128DB28";
+      signature = 0x1E 0x97 0x0E;
+
+      memory "flash"
+          size      = 0x20000;
+          offset    = 0x800000;
+          page_size = 0x200;
+          readsize  = 0x100;
+      ;
+
+      memory "eeprom"
+          size      = 0x200;
+          offset    = 0x1400;
+          page_size = 0x1;
+          readsize  = 0x100;
+      ;
+  ;
+  
+
+USERROW memory has not been defined for new devices except for 
+experimental addition for AVR128DB28. The point of USERROW is to 
+provide ability to write configuration details to already locked
+device and currently SerialUPDI interface supports this feature,
+but it hasn't been tested on wide variety of chips. Treat this as
+something experimental at this point. Please note: on locked devices
+it's not possible to read back USERROW contents when written, so
+the automatic verification will most likely fail and to prevent
+error messages, use *-V*.
+
+Please note that SerialUPDI interface is pretty new and some
+issues are to be expected. In case you run into them, please
+make sure to run the intended command with debug output enabled
+(*-v -v -v*) and provide this verbose output with your
+bug report. You can also try to perform the same action using
+*pymcuprog* (`https://github.com/microchip-pic-avr-tools/pymcuprog <https://github.com/microchip-pic-avr-tools/pymcuprog>`_)
+utility with *-v debug* and provide its output too.
+You will notice that both outputs are pretty similar, and this
+was implemented like that on purpose - it was supposed to make
+analysis of UPDI protocol quirks easier.

+Unix
+====
+
+
+.. _Unix_Installation:
+
+Unix Installation
+-----------------
+
+To build and install from the source tarball on Unix like systems:
+
+::
+
+  $ gunzip -c avrdude-6.99-20211218.tar.gz | tar xf -
+  $ cd avrdude-6.99-20211218
+  $ ./configure
+  $ make
+  $ su root -c 'make install'
+  
+
+The default location of the install is into `/usr/local` so you
+will need to be sure that `/usr/local/bin` is in your `PATH`
+environment variable.
+
+If you do not have root access to your system, you can do the
+following instead:
+
+::
+
+  $ gunzip -c avrdude-6.99-20211218.tar.gz | tar xf -
+  $ cd avrdude-6.99-20211218
+  $ ./configure --prefix=$HOME/local
+  $ make
+  $ make install
+  
+
+.. _FreeBSD_Installation:
+
+FreeBSD Installation
+^^^^^^^^^^^^^^^^^^^^
+
+AVRDUDE is installed via the FreeBSD Ports Tree as follows:
+
+::
+
+  % su - root
+  # cd /usr/ports/devel/avrdude
+  # make install
+  
+
+If you wish to install from a pre-built package instead of the source,
+you can use the following instead:
+
+::
+
+  % su - root
+  # pkg_add -r avrdude
+  
+
+Of course, you must be connected to the Internet for these methods to
+work, since that is where the source as well as the pre-built package is
+obtained.
+
+.. _Linux_Installation:
+
+Linux Installation
+^^^^^^^^^^^^^^^^^^
+
+On rpm based Linux systems (such as RedHat, SUSE, Mandrake, etc.), you
+can build and install the rpm binaries directly from the tarball:
+
+::
+
+  $ su - root
+  # rpmbuild -tb avrdude-6.99-20211218.tar.gz
+  # rpm -Uvh /usr/src/redhat/RPMS/i386/avrdude-6.99-20211218-1.i386.rpm
+  
+
+Note that the path to the resulting rpm package, differs from system
+to system. The above example is specific to RedHat.
+
+.. _Unix_Configuration_Files:
+
+Unix Configuration Files
+------------------------
+
+When AVRDUDE is build using the default *--prefix* configure
+option, the default configuration file for a Unix system is located at
+`/usr/local/etc/avrdude.conf`.  This can be overridden by using the
+*-C* command line option.  Additionally, the user's home directory
+is searched for a file named `.avrduderc`, and if found, is used to
+augment the system default configuration file.
+
+.. _FreeBSD_Configuration_Files:
+
+FreeBSD Configuration Files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When AVRDUDE is installed using the FreeBSD ports system, the system
+configuration file is always `/usr/local/etc/avrdude.conf`.
+
+.. _Linux_Configuration_Files:
+
+Linux Configuration Files
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When AVRDUDE is installed using from an rpm package, the system
+configuration file will be always be `/etc/avrdude.conf`.
+
+.. _Unix_Port_Names:
+
+Unix Port Names
+---------------
+
+The parallel and serial port device file names are system specific.
+The following table lists the default names for a given system.
+
+@multitable @columnfractions .30 .30 .30
+* @strong{System}
+@tab @strong{Default Parallel Port}
+@tab @strong{Default Serial Port}
+* FreeBSD
+@tab `/dev/ppi0`
+@tab `/dev/cuad0`
+* Linux
+@tab `/dev/parport0`
+@tab `/dev/ttyS0`
+* Solaris
+@tab `/dev/printers/0`
+@tab `/dev/term/a`
+@end multitable
+
+On FreeBSD systems, AVRDUDE uses the ppi(4) interface for
+accessing the parallel port and the sio(4) driver for serial port
+access.
+
+On Linux systems, AVRDUDE uses the ppdev interface for
+accessing the parallel port and the tty driver for serial port
+access.
+
+On Solaris systems, AVRDUDE uses the ecpp(7D) driver for
+accessing the parallel port and the asy(7D) driver for serial port
+access.
+
+.. _Unix_Documentation:
+
+Unix Documentation
+------------------
+
+AVRDUDE installs a manual page as well as info, HTML and PDF
+documentation.  The manual page is installed in
+`/usr/local/man/man1` area, while the HTML and PDF documentation
+is installed in `/usr/local/share/doc/avrdude` directory.  The
+info manual is installed in `/usr/local/info/avrdude.info`.
+
+Note that these locations can be altered by various configure options
+such as *--prefix*.
+
+.. _Windows:
+
+Windows
+=======
+
+
+.. _Installation:
+
+Installation
+------------
+
+A Windows executable of avrdude is included in WinAVR which can be found at
+`http://sourceforge.net/projects/winavr <http://sourceforge.net/projects/winavr>`_. WinAVR is a suite of executable, 
+open source software development tools for the AVR for the Windows platform.
+
+There are two options to build avrdude from source under Windows.
+The first one is to use Cygwin (`http://www.cygwin.com/ <http://www.cygwin.com/>`_).
+
+To build and install from the source tarball for Windows (using Cygwin):
+
+::
+
+  $ set PREFIX=<your install directory path>
+  $ export PREFIX
+  $ gunzip -c avrdude-6.99-20211218.tar.gz | tar xf -
+  $ cd avrdude-6.99-20211218
+  $ ./configure LDFLAGS="-static" --prefix=$PREFIX --datadir=$PREFIX 
+  --sysconfdir=$PREFIX/bin --enable-versioned-doc=no
+  $ make
+  $ make install
+  
+
+Note that recent versions of Cygwin (starting with 1.7) removed the
+MinGW support from the compiler that is needed in order to build a
+native Win32 API binary that does not require to install the Cygwin
+library `cygwin1.dll` at run-time.  Either try using an older
+compiler version that still supports MinGW builds, or use MinGW
+(`http://www.mingw.org/ <http://www.mingw.org/>`_) directly.

+Configuration file names
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+AVRDUDE on Windows looks for a system configuration file name of
+`avrdude.conf` and looks for a user override configuration file of

+
+How AVRDUDE finds the configuration files.
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+AVRDUDE on Windows has a different way of searching for the system and
+user configuration files. Below is the search method for locating the
+configuration files:
+
+
+* 
+  Only for the system configuration file:
+  `<directory from which application loaded>/../etc/avrdude.conf`
+
+* 
+  The directory from which the application loaded.
+
+* 
+  The current directory.
+
+* 
+  The Windows system directory. On Windows NT, the name of this directory
+  is `SYSTEM32`.
+
+* 
+  Windows NT: The 16-bit Windows system directory. The name of this
+  directory is `SYSTEM`.
+
+* 
+  The Windows directory.
+
+* 
+  The directories that are listed in the PATH environment variable.
+
+
+.. _Port_Names:
+
+Port Names
+----------
+
+
+.. _Serial_Ports:
+
+Serial Ports
+^^^^^^^^^^^^
+
+When you select a serial port (i.e. when using an STK500) use the
+Windows serial port device names such as: com1, com2, etc.
+
+.. _Parallel_Ports:
+
+Parallel Ports
+^^^^^^^^^^^^^^
+
+AVRDUDE will accept 3 Windows parallel port names: lpt1, lpt2, or
+lpt3.  Each of these names corresponds to a fixed parallel port base
+address:
+
+
+
+*lpt1*
+  0x378
+
+
+*lpt2*
+  0x278
+
+
+*lpt3*
+  0x3BC
+
+
+On your desktop PC, lpt1 will be the most common choice. If you are
+using a laptop, you might have to use lpt3 instead of lpt1. Select the
+name of the port the corresponds to the base address of the parallel
+port that you want.
+
+If the parallel port can be accessed through a different
+address, this address can be specified directly, using the common C
+language notation (i. e., hexadecimal values are prefixed by `0x`).
+
+Documentation
+-------------
+
+AVRDUDE installs a manual page as well as info, HTML and PDF
+documentation.  The manual page is installed in
+`/usr/local/man/man1` area, while the HTML and PDF documentation
+is installed in `/usr/local/share/doc/avrdude` directory.  The
+info manual is installed in `/usr/local/info/avrdude.info`.
+
+Note that these locations can be altered by various configure options
+such as *--prefix* and *--datadir*.
+
+@appendix Troubleshooting
+
+In general, please report any bugs encountered via
+@*
+`http://savannah.nongnu.org/bugs/?group=avrdude <http://savannah.nongnu.org/bugs/?group=avrdude>`_.
+
+
+* 
+  Problem: I'm using a serial programmer under Windows and get the following
+  error:
+
+  `avrdude: serial_open(): can't set attributes for device "com1"`,
+
+  Solution: This problem seems to appear with certain versions of Cygwin. Specifying
+  `"/dev/com1"` instead of `"com1"` should help.
+
+* 
+  Problem: I'm using Linux and my AVR910 programmer is really slow.
+
+  Solution (short): `setserial `port` low_latency`
+
+  Solution (long):
+  There are two problems here. First, the system may wait some time before it
+  passes data from the serial port to the program. Under Linux the following
+  command works around this (you may need root privileges for this).
+
+  `setserial `port` low_latency`
+
+  Secondly, the serial interface chip may delay the interrupt for some time.
+  This behaviour can be changed by setting the FIFO-threshold to one. Under Linux this
+  can only be done by changing the kernel source in `drivers/char/serial.c`.
+  Search the file for `UART_FCR_TRIGGER_8` and replace it with `UART_FCR_TRIGGER_1`. Note that overall performance might suffer if there
+  is high throughput on serial lines. Also note that you are modifying the kernel at
+  your own risk.
+
+* 
+  Problem: I'm not using Linux and my AVR910 programmer is really slow.
+
+  Solutions: The reasons for this are the same as above.
+  If you know how to work around this on your OS, please let us know.
+
+* 
+  Problem: Updating the flash ROM from terminal mode does not work with the
+  JTAG ICEs.
+
+  Solution: None at this time.  Currently, the JTAG ICE code cannot
+  write to the flash ROM one byte at a time.
+
+* 
+  Problem: Page-mode programming the EEPROM (using the -U option) does
+  not erase EEPROM cells before writing, and thus cannot overwrite any
+  previous value != 0xff.
+
+  Solution: None.  This is an inherent feature of the way JTAG EEPROM
+  programming works, and is documented that way in the Atmel AVR
+  datasheets.
+  In order to successfully program the EEPROM that way, a prior chip
+  erase (with the EESAVE fuse unprogrammed) is required.
+  This also applies to the STK500 and STK600 in high-voltage programming mode.
+
+* 
+  Problem: How do I turn off the `DWEN` fuse?
+
+  Solution: If the `DWEN` (debugWire enable) fuse is activated,
+  the `/RESET` pin is not functional anymore, so normal ISP
+  communication cannot be established.
+  There are two options to deactivate that fuse again: high-voltage
+  programming, or getting the JTAG ICE mkII talk debugWire, and
+  prepare the target AVR to accept normal ISP communication again.
+
+  The first option requires a programmer that is capable of high-voltage
+  programming (either serial or parallel, depending on the AVR device),
+  for example the STK500.  In high-voltage programming mode, the
+  `/RESET` pin is activated initially using a 12 V pulse (thus the
+  name *high voltage*), so the target AVR can subsequently be
+  reprogrammed, and the `DWEN` fuse can be cleared.  Typically, this
+  operation cannot be performed while the AVR is located in the target
+  circuit though.
+
+  The second option requires a JTAG ICE mkII that can talk the debugWire
+  protocol.  The ICE needs to be connected to the target using the
+  JTAG-to-ISP adapter, so the JTAG ICE mkII can be used as a debugWire
+  initiator as well as an ISP programmer.  AVRDUDE will then be activated
+  using the `jtag2isp` programmer type.  The initial ISP
+  communication attempt will fail, but AVRDUDE then tries to initiate a
+  debugWire reset.  When successful, this will leave the target AVR in a
+  state where it can accept standard ISP communication.  The ICE is then
+  signed off (which will make it signing off from the USB as well), so
+  AVRDUDE has to be called again afterwards.  This time, standard ISP
+  communication can work, so the `DWEN` fuse can be cleared.
+
+  The pin mapping for the JTAG-to-ISP adapter is:
+
+  @multitable @columnfractions .2 .2
+* @strong{JTAG pin} @tab @strong{ISP pin}
+* 1 @tab 3
+* 2 @tab 6
+* 3 @tab 1
+* 4 @tab 2
+* 6 @tab 5
+* 9 @tab 4
+  @end multitable
+
+* 
+  Problem: Multiple USBasp or USBtinyISP programmers connected simultaneously are not
+  found.
+
+  Solution: The USBtinyISP code supports distinguishing multiple
+  programmers based on their bus:device connection tuple that describes
+  their place in the USB hierarchy on a specific host.  This tuple can
+  be added to the `-P usb` option, similar to adding a serial number
+  on other USB-based programmers.
+
+  The actual naming convention for the bus and device names is
+  operating-system dependent; AVRDUDE will print out what it found
+  on the bus when running it with (at least) one `-v` option.
+  By specifying a string that cannot match any existing device
+  (for example, `-P usb:xxx`), the scan will list all possible
+  candidate devices found on the bus.
+
+  Examples:
+  ::
+
+    avrdude -c usbtiny -p atmega8 -P usb:003:025 (Linux)
+    avrdude -c usbtiny -p atmega8 -P usb:/dev/usb:/dev/ugen1.3 (FreeBSD 8+)
+    avrdude -c usbtiny -p atmega8 \\
+      -P usb:bus-0:\\\\.\\libusb0-0001--0x1781-0x0c9f (Windows)
+    
+
+* 
+  Problem: I cannot do ... when the target is in debugWire mode.
+
+  Solution: debugWire mode imposes several limitations.
+
+  The debugWire protocol is Atmel's proprietary one-wire (plus ground)
+  protocol to allow an in-circuit emulation of the smaller AVR devices,
+  using the `/RESET` line.
+  DebugWire mode is initiated by activating the `DWEN`
+  fuse, and then power-cycling the target.
+  While this mode is mainly intended for debugging/emulation, it
+  also offers limited programming capabilities.
+  Effectively, the only memory areas that can be read or programmed
+  in this mode are flash ROM and EEPROM.
+  It is also possible to read out the signature.
+  All other memory areas cannot be accessed.
+  There is no
+  *chip erase*
+  functionality in debugWire mode; instead, while reprogramming the
+  flash ROM, each flash ROM page is erased right before updating it.
+  This is done transparently by the JTAG ICE mkII (or AVR Dragon).
+  The only way back from debugWire mode is to initiate a special
+  sequence of commands to the JTAG ICE mkII (or AVR Dragon), so the
+  debugWire mode will be temporarily disabled, and the target can
+  be accessed using normal ISP programming.
+  This sequence is automatically initiated by using the JTAG ICE mkII
+  or AVR Dragon in ISP mode, when they detect that ISP mode cannot be
+  entered.
+
+* 
+  Problem: I want to use my JTAG ICE mkII to program an
+  Xmega device through PDI.  The documentation tells me to use the
+  *XMEGA PDI adapter for JTAGICE mkII* that is supposed to ship
+  with the kit, yet I don't have it.
+
+  Solution: Use the following pin mapping:
+
+  @multitable @columnfractions .2 .2 .2 .2
+* @strong{JTAGICE} @tab @strong{Target} @tab @strong{Squid cab-} @tab @strong{PDI}
+* @strong{mkII probe} @tab @strong{pins} @tab @strong{le colors} @tab @strong{header}

+* 4 (VTref) @tab VTref   @tab Purple @tab 2
+* 5 (TMS)   @tab         @tab Blue   @tab
+* 6 (nSRST) @tab PDI_CLK @tab Green  @tab 5
+* 7 (N.C.)  @tab         @tab Yellow @tab
+* 8 (nTRST) @tab         @tab Orange @tab
+* 9 (TDI)   @tab PDI_DATA @tab Red   @tab 1
+* 10 (GND)  @tab         @tab Brown  @tab
+  @end multitable
+
+* 
+  Problem: I want to use my AVR Dragon to program an
+  Xmega device through PDI.  
+
+  Solution: Use the 6 pin ISP header on the Dragon and the following pin mapping:
+
+  @multitable @columnfractions .2 .2
+* @strong{Dragon} @tab @strong{Target}
+* @strong{ISP Header} @tab @strong{pins}
+* 1 (MISO)  @tab PDI_DATA
+* 2 (VCC)   @tab VCC
+* 3 (SCK)   @tab
+* 4 (MOSI)  @tab
+* 5 (RESET) @tab PDI_CLK / RST
+* 6 (GND)   @tab GND
+  @end multitable
+
+* 
+  Problem: I want to use my AVRISP mkII to program an
+  ATtiny4/5/9/10 device through TPI.  How to connect the pins?
+
+  Solution: Use the following pin mapping:
+
+  @multitable @columnfractions .2 .2 .2
+* @strong{AVRISP} @tab @strong{Target} @tab @strong{ATtiny}
+* @strong{connector} @tab @strong{pins} @tab @strong{pin #}
+* 1 (MISO)  @tab TPIDATA  @tab 1
+* 2 (VTref) @tab Vcc      @tab 5
+* 3 (SCK)   @tab TPICLK   @tab 3
+* 4 (MOSI)  @tab          @tab
+* 5 (RESET) @tab /RESET   @tab 6
+* 6 (GND)   @tab GND      @tab 2
+  @end multitable
+
+* 
+  Problem: I want to program an ATtiny4/5/9/10 device using a serial/parallel 
+  bitbang programmer.  How to connect the pins?
+
+  Solution: Since TPI has only 1 pin for bi-directional data transfer, both 
+  `MISO` and `MOSI` pins should be connected to the `TPIDATA` pin 
+  on the ATtiny device.
+  However, a 1K resistor should be placed between the `MOSI` and `TPIDATA`.
+  The `MISO` pin connects to `TPIDATA` directly.
+  The `SCK` pin is connected to `TPICLK`.
+
+  In addition, the `Vcc`, `/RESET` and `GND` pins should 
+  be connected to their respective ports on the ATtiny device.
+
+* 
+  Problem: How can I use a FTDI FT232R USB-to-Serial device for bitbang programming?
+
+  Solution: When connecting the FT232 directly to the pins of the target Atmel device, 
+  the polarity of the pins defined in the `programmer` definition should be 
+  inverted by prefixing a tilde. For example, the `dasa` programmer would 
+  look like this when connected via a FT232R device (notice the tildes in 
+  front of pins 7, 4, 3 and 8):
+
+  ::
+
+    programmer
+      id    = "dasa_ftdi";
+      desc  = "serial port banging, reset=rts sck=dtr mosi=txd miso=cts";
+      type  = serbb;
+      reset = ~7;
+      sck   = ~4;
+      mosi  = ~3;
+      miso  = ~8;
+    ;
+    
+
+  Note that this uses the FT232 device as a normal serial port, not using the 
+  FTDI drivers in the special bitbang mode.
+
+* 
+  Problem: My ATtiny4/5/9/10 reads out fine, but any attempt to program
+  it (through TPI) fails.  Instead, the memory retains the old contents.
+
+  Solution: Mind the limited programming supply voltage range of these
+  devices.
+
+  In-circuit programming through TPI is only guaranteed by the datasheet
+  at Vcc = 5 V.
+
+* 
+  Problem: My ATxmega...A1/A2/A3 cannot be programmed through PDI with
+  my AVR Dragon.  Programming through a JTAG ICE mkII works though, as does
+  programming through JTAG.
+
+  Solution: None by this time (2010 Q1).
+
+  It is said that the AVR Dragon can only program devices from the A4
+  Xmega sub-family.
+
+* 
+  Problem: when programming with an AVRISPmkII or STK600, AVRDUDE hangs
+  when programming files of a certain size (e.g. 246 bytes).  Other
+  (larger or smaller) sizes work though.
+
+  Solution: This is a bug caused by an incorrect handling of zero-length
+  packets (ZLPs) in some versions of the libusb 0.1 API wrapper that ships
+  with libusb 1.x in certain Linux distributions.  All Linux systems with
+  kernel versions < 2.6.31 and libusb >= 1.0.0 < 1.0.3 are reported to be
+  affected by this.
+
+  See also: `http://www.libusb.org/ticket/6 <http://www.libusb.org/ticket/6>`_
+
+* 
+  Problem: after flashing a firmware that reduces the target's clock
+  speed (e.g. through the `CLKPR` register), further ISP connection
+  attempts fail.
+
+  Solution: Even though ISP starts with pulling `/RESET` low, the
+  target continues to run at the internal clock speed as defined by the
+  firmware running before.  Therefore, the ISP clock speed must be
+  reduced appropriately (to less than 1/4 of the internal clock speed)
+  using the -B option before the ISP initialization sequence will
+  succeed.
+
+  As that slows down the entire subsequent ISP session, it might make
+  sense to just issue a *chip erase* using the slow ISP clock
+  (option `-e`), and then start a new session at higher speed.
+  Option `-D` might be used there, to prevent another unneeded
+  erase cycle.

+Under a Linux installation with direct access to the SPI bus and GPIO
+pins, such as would be found on a Raspberry Pi, the ``linuxspi''
+programmer type can be used to directly connect to and program a chip
+using the built in interfaces on the computer. The requirements to use
+this type are that an SPI interface is exposed along with one GPIO
+pin. The GPIO serves as the reset output since the Linux SPI drivers
+do not hold slave select down when a transfer is not occuring and thus
+it cannot be used as the reset pin. A readily available level
+translator should be used between the SPI bus/reset GPIO and the chip
+to avoid potentially damaging the computer's SPI controller in the
+event that the chip is running at 5V and the SPI runs at 3.3V. The
+GPIO chosen for reset can be configured in the avrdude configuration
+file using the
+.Li reset
+entry under the linuxspi programmer, or
+directly in the port specification. An external pull-up resistor

+Under a Linux installation with direct access to the SPI bus and GPIO
+pins, such as would be found on a Raspberry Pi, the ``linuxspi''
+programmer type can be used to directly connect to and program a chip
+using the built in interfaces on the computer. The requirements to use
+this type are that an SPI interface is exposed along with one GPIO
+pin. The GPIO serves as the reset output since the Linux SPI drivers
+do not hold slave select down when a transfer is not occuring and thus
+it cannot be used as the reset pin. A readily available level
+translator should be used between the SPI bus/reset GPIO and the chip
+to avoid potentially damaging the computer's SPI controller in the
+event that the chip is running at 5V and the SPI runs at 3.3V. The
+GPIO chosen for reset can be configured in the avrdude configuration
+file using the @code{reset} entry under the linuxspi programmer, or
+directly in the port specification. An external pull-up resistor
+should be connected between the AVR's reset pin and Vcc. If Vcc is not
+the same as the SPI voltage, this should be done on the AVR side of
+the level translator to protect the hardware from damage.
+
+On a Raspberry Pi, header J8 provides access to the SPI and GPIO
+lines.
+
+Typically, pins 19, 21, and 23 are SPI MOSI, MISO, and SCK, while
+pins 24 and 26 would serve as CE outputs. So, close to these pins
+is pin 22 as GPIO25 which can be used as /RESET, and pin 25 can
+be used as GND.

+@end example
+
+There are several limitations in current SerialUPDI/AVRDUDE integration,
+listed below.
+
+At the end of each run there are fuse values being presented to the user.
+For most of the UPDI-enabled devices these definitions (low fuse, high
+fuse, extended fuse) have no meaning whatsoever, as they have been 
+simply replaced by array of fuses: fuse0..9. Therefore you can simply
+ignore this particular line of AVRDUDE output.
+
+In connection to the above, @emph{safemode} has no meaning in context
+of UPDI devices and should be ignored.
+
+Currently available devices support only UPDI NVM programming model 0 
+and 2, but there is also experimental implementation of model 3 - not
+yet tested.
+
+One of the core AVRDUDE features is verification of the connection by
+reading device signature prior to any operation, but this operation
+is not possible on UPDI locked devices. Therefore, to be able to 
+connect to such a device, you have to provide @option{-F} to override
+this check.
+
+Please note: using @option{-F} during write operation to locked device 
+will force chip erase. Use carefully.
+
+Another issue you might notice is slow performance of EEPROM writing
+using SerialUPDI for AVR Dx devices. This can be addressed by changing
+@emph{avrdude.conf} section for this device - changing EEPROM page 
+size to 0x20 (instead of default 1), like so:
+
+@example
+#------------------------------------------------------------
+# AVR128DB28
+#------------------------------------------------------------
+
+part parent    ".avrdx"
+    id        = "avr128db28";
+    desc      = "AVR128DB28";
+    signature = 0x1E 0x97 0x0E;
+
+    memory "flash"
+        size      = 0x20000;
+        offset    = 0x800000;
+        page_size = 0x200;
+        readsize  = 0x100;
+    ;
+
+    memory "eeprom"
+        size      = 0x200;
+        offset    = 0x1400;
+        page_size = 0x1;
+        readsize  = 0x100;
+    ;
+;
+@end example
+
+USERROW memory has not been defined for new devices except for 
+experimental addition for AVR128DB28. The point of USERROW is to 
+provide ability to write configuration details to already locked
+device and currently SerialUPDI interface supports this feature,
+but it hasn't been tested on wide variety of chips. Treat this as
+something experimental at this point. Please note: on locked devices
+it's not possible to read back USERROW contents when written, so
+the automatic verification will most likely fail and to prevent
+error messages, use @option{-V}.
+
+Please note that SerialUPDI interface is pretty new and some
+issues are to be expected. In case you run into them, please
+make sure to run the intended command with debug output enabled
+(@option{-v -v -v}) and provide this verbose output with your
+bug report. You can also try to perform the same action using
+@emph{pymcuprog} (@url{https://github.com/microchip-pic-avr-tools/pymcuprog})
+utility with @option{-v debug} and provide its output too.
+You will notice that both outputs are pretty similar, and this
+was implemented like that on purpose - it was supposed to make
+analysis of UPDI protocol quirks easier.

+
+// Notes:
+// This file adds support for the Micronucleus bootloader V1 and V2,
+// so you do no longer need the Micronucleus command-line utility.
+//
+// This bootloader is typically used on small ATtiny boards,
+// such as Digispark (ATtiny85), Digispark Pro (ATtiny167),
+// and the respective clones.
+// By default, it bootloader uses the VID/PID 16d0:0753 (MCS Digistump).
+//
+// As the micronucleus bootloader is optimized for size, it implements
+// writing to flash memory only. Since it does not support reading,
+// use the -V option to prevent avrdude from verifing the flash memory.
+// To have avrdude wait for the device to be connected, use the
+// extended option '-x wait'.
+//
+// Example:
+// avrdude -c micronucleus -p t85 -x wait -V -U flash:w:main.hex
