In addition to the traditional STK500, this implementation is also used by all the more modern Atmel tools (AVRISPmkII, JTAGICEmkII in ISP mode, STK600 in ISP mode). - The -B option can be suffixed with "Hz", "kHz", or "MHz", in order to specify a bitclock frequency rather than period. - Print part id after signature (patch #8440 ) - buspirate: Also support "cpufreq" extended parameter in binary mode (patch #8504 ) - The "-P net:" syntax (forwarding of serial data over TCP) is now also implemented for Win32 systems. - Allow for arbitrary serial baudrates under Linux (OSX and *BSD could already handle it). * New devices supported: - AT90PWM216 (bug #42310: New part description for AT90PWM216) - ATmega32M1 (patch #7694 Add support for the atmega32m1) * New programmers supported: - ftdi_syncbb + uncompatino, ttl232r (FTDI TTL232R-5V with ICSP adapter) (patch #8529 2 more ftdi_syncbb devices) * Bugfixes - bug #45727: Wrong atmega8u2 flash parameters - bug #46020: Add TIAO TUMPA to the conf file. - bug #46021: Please add read in the memory lock section of ATtiny85 - bug #42337 avrdude.conf updates for UM232H/CM232H - bug #42056: double free or corruption triggered at exit - bug #42158: Linux GPIO - Source Typo - bug #42516 spelling-error-in-binary - patch #8419 fix ftdi_syncbb hang with libftdi 1 - bug #43002 usbasp debug output typo - patch #8511 Fix reset on FT245R - bug #40142 Floating point exception on Ubuntu 10.04 - bug #22248: Read efuse error (partial fix) - bug #42267: jtag3isp fails to read lock and fuse bytes directly after changing lock byte - bug #41561: AVRDUDE 6.0.1/USBasp doesn't write first bytes of flash page - bug #43078: AVRDUDE crashes after sucessfully reading/writing eeprom - bug #43137: Writing and reading incorrect pages when using jtagicemkI - bug #40870: config nitpick: ATtiny25/45/85 have 1 calibration byte not 2 - bug #42908: no external reset at JTAGICE3 - patch #8437: [PATCH] Serial-over-ethernet for Win32 - bug #44717: avrdude creates empty flash dump * Internals: - Removing exit calls from config parser - bug #42662 clang warnings under FreeBSD 10.x Version 6.1: * Major changes compared to the previous version: - Atmel EDBG protocol support added (JTAGICE3, XplainedPro, Atmel-ICE) * New programmers supported: - Atmel DFU, using FLIP protocol version 1 (AT90USB and ATmega*U* devices), or version 2 (Xmega devices) - Atmel-ICE (ARM/AVR), JTAG, PDI, debugWIRE, ISP modi * Bugfixes - bug #40055: AVRDUDE segfaults when writing eeprom - bug #40085: Typo fix in fuses report (for 6.1-svn-20130917) - bug #40782: Verify errors for object size > 16 k on x32e5 due to typo in avrdude.conf - bug #40817: Elf file support (possibly) not working on 6.0.1 windows build - bug #40897: AT Mega2560 not correctly programmed with stk500(v1) ISP (solution patch) - bug #41357: OS X: Avrdude messes with the usb stack? - bug #41402: dfu.c missing include - patch #7896: DFU FLIPv2 programming support - patch #XXXX: xxx * Internals: - (Some) programmers can take a list of USB PIDs now. Version 6.0: * Major changes compared to the previous version: - Programmer types in configuration file are no longer keywords but specified as string. So you need to change 'type = XYZ;' to 'type = "XYZ";' in own config files. (internal: The parser does not need to know all programmer types now, new programmers will update only the table in pgm_type.c.) - The erase cycle counter (formerly options -y / -Y) has been removed. - Specifying a -U option without a memory type (short form of option argument list) now defaults to "application" memory for Xmega devices, and "flash" for everything else. This ensures the Xmega bootloader is not accidentally touched. - For programmers that support it, the default erase method is a page erase now, rather than a chip erase (Xmega only). - Keep track of input file contents Memory segments are being tracked to remember whether they've been actually read from a file. Only segments that came from a file are being programmed into the device, or considered for verification. This drastically improves handling speed for sparse files (e.g. files that have a second bootloader segment), and it ensures the device contents is actually compared for everything mentioned in the file (even in case the file has large 0xFF blocks). - The -U option now accepts ELF files as input files, and extracts the appropriate section contents that matches the requested memory region. To enable this feature, the host system used for the compilation must have a libelf around, including the respective header files (i.e., package "libelf-devel" on many Linux systems). - Programmers and parts lists They are now sorted at output with '-c ?'/'-p ?'. (patch #7671: Sorting programmers and parts lists for console output) Programmers and parts lists in documentation generated from lists mentioned above. (patch #7687: Autogenerating programmers and parts lists for docs) Output list of programmer types with '-c ?type', add list to documentation - Configuration files now accepts parent parts/programmers, parts starting with '.' (eg. .xmega) are not included in output parts list and can be used as abstract parents (bug #34302: Feature request : device configuration with parent classes) (patch #7688: Implement parent programmers feature) - Additional config files which are read after default can be specified on command line using '-C +filename' (patch #7699 Read additional config files) - "Safemode" can now be turned off by default from within a configuration file (like ~/.avrduderc). - The new option -l logfile allows to redirect diagnostic messages to a logfile rather than stderr. Useful to record debugging traces, in particular in environments which do not offer shell-style redirection functionality for standard streams. - When leaving debugWIRE mode, immediately retry with ISP rather than bailing out completely. - The USBasp programmer implementation now supports detailed traces with -vvv, and device communication traces with -vvvv. - The "verbose" terminal mode command allows to query or modify the verbosity level. * New devices supported: - ATmega48P (patch #7629 add support for atmega48p) - AT90PWM316 (bug #21797: AT90PWM316: New part description) - ATxmega16D4, ATxmega32D4, ATxmega64D4, ATxmega128D4 - ATmega256RFR2, ATmega128RFR2, ATmega64RFR2, ATmega2564RFR2, ATmega1284RFR2, ATmega644RFR2 -

Contributed by Martin Thomas * Add support for - ATmega48, ATmega88 (contributed by Galen Seitz) - ATtiny2313 (contributed by Bob Paddock) - ATtiny13 (contributed by Pawel Moll) * Added command to change the SCK of STK500-programmers. Now it is possible to program uC with slow oscillator. Contributed by Galen Seitz * Baudrate for serial programmers (STK500 and AVR910) is configurable in the config or at the command-line. This way some more tweaked bootloaders and programmers can be used. * Deprecated options have been removed. Now the "-U" option must be used. * MacOS X now supported by default. Version 4.3.0: * Added support for "Butterfly" evaluation board. * Make cycle-count work with AVR910-programmers. * Added "Troubleshooting"-Appendix to the manual. * Add ATmega8515 support. Contributed by: Matthias Weißer * Add ATmega64 support. Contributed by: Erik Christiansen * Improved polling algorithm to speed up programming of byte oriented parallel programmers. Contributed by: Jan-Hinnerk Reichert * Add "fuse" and "lock" definitions for the AT90S8535. * STK500 skips empty pages in paged write resulting in faster downloads when there are empty blocks in between code (such as files that contain application code and bootloader code). Version 4.2.0: * Add basic support for reading and writing fuses via SPI with avr910 programmers. Submitted by Jan-Hinnerk Reichert . * Perform an auto erase before programming if the flash memory is anywhere specified to be written by any of the -U requests. Old style memory specification options (-f, -i, -I, -m, and -o) are deprecated in favor of the new -U options. Auto erase is disabled if any of the old-style options (specifically -i and -o) are specified. * Add new -U option for specifying programming operations - allows multiple memory operations on a single command line. * New progress reporting, looks nicer and is nicer to wrapper environments such as emacs. * Fix long-standing timing (verify) problems on Windows platform. Submitted by Alex Shepherd . * Add new file format option - 'm' for "immediate mode." In this case, the filename argument of the -o, -i, or -U options is treated as the data for uploading - useful for specifying fuse bits without having to create a single-byte file for uploading. * Add support for displaying and setting the various STK500 operational parameters (Vtarget, Varef, Master clock). * Add 'picoweb' programming cable programmer. Contributed by Rune Christensen . * Add support for the sp12 programmer. Submitted by Larry Barello . Version 4.1.0 * Add support for the Bascom SAMPLE programmer. Submitted by Larry Barello . * Add support for avr910 type programmers (mcu00100, pavr avr910, etc). * Support new devices: ATmega8535, ATtiny26 Version 4.0.0 * Now support Linux - added by "Theodore A. Roth" . * Now support Windows - added by "Eric B. Weddington" . * Use 'configure' scripts to tailor the code to the system avrdude is getting ready to be compiled on - added by "Theodore A. Roth" . * Motorola S-Record support - submitted by "Alexey V.Levdikov " . * Support parallel programming on the STK500. Introduce 'pagel' and 'bs2' keywords to the config file for this purpose. * Add support for the AT90S2343 * Add support for the ATmega169 * Add ability to specify system defaults within the config file (default parallel port, default serial port). * Specify the default programmer seperately from the programmer definition. This is now done in the config file using the 'default_programmer' keyword. * Support a per-user config file (~/.avrduderc) so that one can override system wide defaults if desired. * Follow the datasheet more closely for several parts in the "retry" code when entering programming mode fails initially. Introduce 'retry_pulse' to the config file for this purpose. Version 3.1.0 * This change represents a name change only. There is currently an effort to port AVRPROG to other platforms including Linux and Windows. Since Atmel's programmer binary that's included within their AVR Studio software is named AVRPROG.EXE on the Windows OS, there is the chance for confusion if we keep calling this program AVRPROG as well. Up until now the name hasn't really been a problem since there was no chance to confuse 'avrprog' on Unix with Atmel's AVRPROG because Atmel's tools only run on Windows. But with the Unix 'avrprog' possibly being ported to Windows, I felt a name change was the best way to avoid problems. So - from this point forward, my FreeBSD Unix program formerly known as AVRPROG will subsequently be known as AVRDUDE (AVR Downloader/UploaDEr). This change also represents a time when the AVRDUDE sources move from my own private repository to a public repository. This will give other developers a chance to port AVRDUDE to other platforms and extend its functionality to support additional programming hardware, etc. So goodbye AVRPROG, welcome AVRDUDE! Version 3.0.0 * Rewrite parts of the code to make it easy to support other types of programmers besides the directly connected parallel port programmer (PPI). * Add support for Atmel's STK500 programmer/development board. The STK500's "paged mode" read/write is supported which makes this programmer very fast. This is sorely needed on parts with large memories such as the ATmega128. My 12K test program burns in about 5 seconds, add another 5 to read it back out for verification. Version 2.1.5: * 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. Feature contributed by Rick C. Petty . * When in interactive terminal mode and dumping memory using the 'dump ' command without any address information, and the end of memory is reached, wrap back around to zero on the next invocation. Version 2.1.4: * Fix -Y option. Version 2.1.3: * Be backward compatible when reading 2-byte rewrite cycle counters as written by avrprog version 2.1.0. Version 2.1.1 changed over to a 4-byte counter, which caused avrprog versions 2.1.1 and 2.1.2 to report a negative count for parts that were initialized using version 2.1.0. Thanks to Joerg Wunsch for noticing this. Version 2.1.2: * Add '-V' option to disable automatic verify check with uploading data. Version 2.1.1: * Fix ATmega128 instruction sequences for reading fuse bits - contributed by Joerg Wunsch. * Modify erase-rewrite cycle counter code to use a 4 byte counter instead of a two byte counter. Version 2.1.0: * Implement a per-part erase-rewrite cycle counter; requires the use of two bytes of EEPROM memory. Version 2.0.5: * Support for ATtiny15 - contributed by Asher Hoskins Version 2.0.4: * Config file fixes for various parts. Version 2.0.3: * Work around problem programming fuse bits on parts like the at90s4433 as described in the following errata: http://www.atmel.com/atmel/acrobat/doc1280.pdf * Add part definition for at90s4414, at90s4433. * Add fuse/lock bit memory instructions for the at90s1200, at90s2333, at90s4433 and at90s8515. * Fix setting of programmer status LEDs under certain write-fail conditions. Version 2.0.2 : * Fix writing to read-only memories such as the lock bits of the AT90S2313. * Copyright updates. Version 2.0.1 : * Use correct parallel port pins for VCC. * Add programmer definition for Atmel's STK200. * Add programmer definition for the AVR3 board. * Fix address bit encoding for many parts. * Allow the ``BUFF'' signal to be asserted by multiple pins of the parallel port (like VCC) instead of just one. The STK200 appears to need this feature. Version 2.0.0 : * Add support for programming fuse and lock bits if supported by the part. * Move instruction encoding into the config file. Now any part can be supported as long as it uses the same basic serial programming instruction format. * Add part definitions for the ATMega163 and ATMega8 devices. Version 1.4.3 : * Mostly internal code cleanup. Version 1.4.2 : * Fixes for ATMega paged memory support. * Support for ATMega16 device. Version 1.4.1 : * No functional changes, update to Copyrights only. Version 1.4.0 : * Add part definitions to the config file. * Add initial support for Atmel's ATMega paged memory parts. * Config file documentation added. * Add a definition for the Dontronics DT006 programmer. * Fix Intel Hex support for addresses larger than 64k. Version 1.3.0 : * Make programmer pin assignments configurable. Version 1.2.2 : * Initial public release.
