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, modifing 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 (both mkI and mkII, the latter 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 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.
|
|
|
|
The STK500, JTAG ICE, avr910, and avr109/butterfly use the serial port to communicate with the PC.
|
|
The STK600, JTAG ICE mkII, AVRISP mkII, USBasp, and USBtinyISP
|
|
programmers communicate through the USB, using @code{libusb} as a
|
|
platform abstraction layer.
|
|
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
|
|
programer 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
|
|
intented 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, JTAG, debugWire and ISP mode are supported.
|
|
See below for the limitations of debugWire.
|
|
|
|
The AVR Dragon is supported in all modes (ISP, JTAG, 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 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 @code{-B @var{bitclock}}
|
|
option might be required to achieve a stable ISP communication.
|
|
|
|
The USBasp ISP and USBtinyISP adapters are also supported, provided AVRDUDE
|
|
has been compiled with libusb support.
|
|
They both feature simple firwmare-only USB implementations, running on
|
|
an ATmega8 (or ATmega88), or ATtiny2313, respectively.

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 (@url{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.

AVRDUDE is a command line tool, used as follows:
|
|
|
|
@smallexample
|
|
avrdude -p partno @var{options} @dots{}
|
|
@end smallexample
|
|
|
|
@noindent
|
|
Command line options are used to control AVRDUDE's behaviour. The
|
|
following options are recognized:
|
|
|
|
@table @code
|
|
@item -p @var{partno}
|
|
This is the only mandatory option and it tells AVRDUDE what type of part
|
|
(MCU) that is connected to the programmer. The @var{partno} parameter
|
|
is the part's id listed in the configuration file. Specify -p ? to list
|
|
all parts in the configuration file. If a part is unknown
|
|
to AVRDUDE, it means that there is no config file entry for that part,
|
|
but it can be added to the configuration file if you have the Atmel
|
|
datasheet so that you can enter the programming specifications.
|
|
Currently, the following MCU types are understood:

|
|
(**) Flash addressing above 128 KB is not supported by all
|
|
programming hardware. Known to work are jtag2, stk500v2,
|
|
and bit-bang programmers.
|
|
|
|
@item -b @var{baudrate}
|
|
Override the RS-232 connection baud rate specified in the respective
|
|
programmer's entry of the configuration file.
|
|
|
|
@item -B @var{bitclock}
|
|
Specify the bit clock period for the JTAG interface or the ISP clock (JTAG ICE only).
|
|
The value is a floating-point number in microseconds.
|
|
The default value of the JTAG ICE results in about 1 microsecond bit
|
|
clock period, suitable for target MCUs running at 4 MHz clock and
|
|
above.
|
|
Unlike certain parameters in the STK500, the JTAG ICE resets all its
|
|
parameters to default values when the programming software signs
|
|
off from the ICE, so for MCUs running at lower clock speeds, this
|
|
parameter must be specified on the command-line.
|
|
|
|
@item -c @var{programmer-id}
|
|
Specify the programmer to be used. AVRDUDE knows about several common
|
|
programmers. Use this option to specify which one to use. The
|
|
@var{programmer-id} parameter is the programmer's id listed in the
|
|
configuration file. Specify -c ? to list all programmers in the
|
|
configuration file. If you have a programmer that is unknown to
|
|
AVRDUDE, and the programmer is controlled via the PC parallel port,
|
|
there's a good chance that it can be easily added to the configuration
|
|
file without any code changes to AVRDUDE. Simply copy an existing entry
|
|
and change the pin definitions to match that of the unknown programmer.
|
|
Currently, the following programmer ids are understood and supported:

@item -C @var{config-file}
|
|
Use the specified config file for configuration data. This file
|
|
contains all programmer and part definitions that AVRDUDE knows about.
|
|
If you have a programmer or part that AVRDUDE does not know about, you
|
|
can add it to the config file (be sure and submit a patch back to the
|
|
author so that it can be incorporated for the next version). If not
|
|
specified, AVRDUDE reads the configuration file from
|
|
/usr/local/etc/avrdude.conf (FreeBSD and Linux). See Appendix A for
|
|
the method of searching for the configuration file for Windows.
|
|
|
|
@item -D
|
|
Disable auto erase for flash. When the -U option with flash memory is
|
|
specified, avrdude will perform a chip erase before starting any of the
|
|
programming operations, since it generally is a mistake to program the flash
|
|
without performing an erase first. This option disables that.
|
|
Auto erase is not used for ATxmega devices as these devices can
|
|
use page erase before writing each page so no explicit chip erase
|
|
is required.
|
|
Note however that any page not affected by the current operation
|
|
will retain its previous contents.
|
|
|
|
@item -e
|
|
Causes a chip erase to be executed. This will reset the contents of the
|
|
flash ROM and EEPROM to the value `0xff', and clear all lock bits.
|
|
Except for ATxmega devices which can use page erase,
|
|
it is basically a
|
|
prerequisite command before the flash ROM can be reprogrammed again.
|
|
The only exception would be if the new contents would exclusively cause
|
|
bits to be programmed from the value `1' to `0'. Note that in order
|
|
to reprogram EERPOM cells, no explicit prior chip erase is required
|
|
since the MCU provides an auto-erase cycle in that case before
|
|
programming the cell.
|
|
|
|
|
|
@item -E @var{exitspec}[,@dots{}]
|
|
By default, AVRDUDE leaves the parallel port in the same state at exit
|
|
as it has been found at startup. This option modifies the state of the
|
|
`/RESET' and `Vcc' lines the parallel port is left at, according to
|
|
the exitspec arguments provided, as follows:
|
|
|
|
@table @code
|
|
@itemx reset
|
|
The `/RESET' signal will be left activated at program exit, that is it
|
|
will be held low, in order to keep the MCU in reset state afterwards.
|
|
Note in particular that the programming algorithm for the AT90S1200
|
|
device mandates that the `/RESET' signal is active before powering up
|
|
the MCU, so in case an external power supply is used for this MCU type,
|
|
a previous invocation of AVRDUDE with this option specified is one of
|
|
the possible ways to guarantee this condition.
|
|
|
|
@itemx noreset
|
|
The `/RESET' line will be deactivated at program exit, thus allowing the
|
|
MCU target program to run while the programming hardware remains
|
|
connected.
|
|
|
|
@itemx vcc
|
|
This option will leave those parallel port pins active (i. e. high) that
|
|
can be used to supply `Vcc' power to the MCU.
|
|
|
|
@itemx novcc
|
|
This option will pull the `Vcc' pins of the parallel port down at
|
|
program exit.
|
|
|
|
@end table
|
|
|
|
Multiple @var{exitspec} arguments can be separated with commas.
|
|
|
|
|
|
@item -F
|
|
Normally, AVRDUDE tries to verify that the device signature read from
|
|
the part is reasonable before continuing. Since it can happen from time
|
|
to time that a device has a broken (erased or overwritten) device
|
|
signature but is otherwise operating normally, this options is provided
|
|
to override the check.
|
|
Also, for programmers like the Atmel STK500 and STK600 which can
|
|
adjust parameters local to the programming tool (independent of an
|
|
actual connection to a target controller), this option can be used
|
|
together with @option{-t} to continue in terminal mode.
|
|
|
|
@item -i @var{delay}
|
|
For bitbang-type programmers, delay for approximately
|
|
@var{delay}
|
|
microseconds between each bit state change.
|
|
If the host system is very fast, or the target runs off a slow clock
|
|
(like a 32 kHz crystal, or the 128 kHz internal RC oscillator), this
|
|
can become necessary to satisfy the requirement that the ISP clock
|
|
frequency must not be higher than 1/4 of the CPU clock frequency.
|
|
This is implemented as a spin-loop delay to allow even for very
|
|
short delays.
|
|
On Unix-style operating systems, the spin loop is initially calibrated
|
|
against a system timer, so the number of microseconds might be rather
|
|
realistic, assuming a constant system load while AVRDUDE is running.
|
|
On Win32 operating systems, a preconfigured number of cycles per
|
|
microsecond is assumed that might be off a bit for very fast or very
|
|
slow machines.
|
|
|
|
@item -n
|
|
No-write - disables actually writing data to the MCU (useful for
|
|
debugging AVRDUDE).
|
|
|
|
@item -O
|
|
Perform a RC oscillator run-time calibration according to Atmel
|
|
application note AVR053.
|
|
This is only supported on the STK500v2, AVRISP mkII, and JTAG ICE mkII
|
|
hardware.
|
|
Note that the result will be stored in the EEPROM cell at address 0.
|
|
|
|
@item -P @var{port}
|
|
Use port to identify the device to which the programmer is attached.
|
|
Normally, the default parallel port is used, but if the programmer type
|
|
normally connects to the serial port, the default serial port will be
|
|
used. See Appendix A, Platform Dependent Information, to find out the
|
|
default port names for your platform. If you need to use a different
|
|
parallel or serial port, use this option to specify the alternate port name.
|
|
|
|
For the JTAG ICE mkII, if AVRDUDE has been built with libusb support,
|
|
@var{port} may alternatively be specified as
|
|
@code{usb}[:@var{serialno}]. In that case, the JTAG ICE mkII will be
|
|
looked up on USB. If @var{serialno} is also specified, it will be
|
|
matched against the serial number read from any JTAG ICE mkII found on
|
|
USB. The match is done after stripping any existing colons from the
|
|
given serial number, and right-to-left, so only the least significant
|
|
bytes from the serial number need to be given.
|
|
For a trick how to find out the serial numbers of all JTAG ICEs
|
|
attached to USB, see @ref{Example Command Line Invocations}.
|
|
|
|
As the AVRISP mkII device can only be talked to over USB, the very
|
|
same method of specifying the port is required there.
|
|
|
|
For the USB programmer "AVR-Doper" running in HID mode, the port must
|
|
be specified as @var{avrdoper}. Libusb support is required on Unix
|
|
but not on Windows. For more information about AVR-Doper see
|
|
@url{http://www.obdev.at/avrusb/avrdoper.html}.
|
|
|
|
For programmers that attach to a serial port using some kind of
|
|
higher level protocol (as opposed to bit-bang style programmers),
|
|
@var{port} can be specified as @code{net}:@var{host}:@var{port}.
|
|
In this case, instead of trying to open a local device, a TCP
|
|
network connection to (TCP) @var{port} on @var{host}
|
|
is established.
|
|
The remote endpoint is assumed to be a terminal or console server
|
|
that connects the network stream to a local serial port where the
|
|
actual programmer has been attached to.
|
|
The port is assumed to be properly configured, for example using a
|
|
transparent 8-bit data connection without parity at 115200 Baud
|
|
for a STK500.
|
|
|
|
@emph{This feature is currently not implemented for Win32 systems.}
|
|
|
|
|
|
@item -q
|
|
Disable (or quell) output of the progress bar while reading or writing
|
|
to the device. Specify it a second time for even quieter operation.
|
|
|
|
@item -u
|
|
Disables the default behaviour of reading out the fuses three times before
|
|
programming, then verifying at the end of programming that the fuses have not
|
|
changed. If you want to change fuses you will need to specify this option,
|
|
as avrdude will see the fuses have changed (even though you wanted to) and
|
|
will change them back for your "saftey". This option was designed to
|
|
prevent cases of fuse bits magically changing (usually called @emph{safemode}).
|
|
|
|
@item -t
|
|
Tells AVRDUDE to enter the interactive ``terminal'' mode instead of up-
|
|
or downloading files. See below for a detailed description of the
|
|
terminal mode.
|
|
|
|
@item -U @var{memtype}:@var{op}:@var{filename}[:@var{format}]
|
|
Perform a memory operation, equivalent to specifing the @option{-m},
|
|
@option{-i} or @option{-o}, and @option{-f} options, except that
|
|
multiple @option{-U} optins can be specified in order to operate on
|
|
mulitple memories on the same command-line invocation. The
|
|
@var{memtype} field specifies the memory type to operate on. Use
|
|
the @option{-v} option on the command line or the @code{part} command from
|
|
terminal mode to display all the memory types supported by a particular
|
|
device.
|
|
Typically, a device's memory configuration at least contains
|
|
the memory types
|
|
@code{flash}
|
|
and
|
|
@code{eeprom}.
|
|
All memory types currently known are:
|
|
@table @code
|
|
@item calibration
|
|
One or more bytes of RC oscillator calibration data.
|
|
@item eeprom
|
|
The EEPROM of the device.
|
|
@item efuse
|
|
The extended fuse byte.
|
|
@item flash
|
|
The flash ROM of the device.
|
|
@item fuse
|
|
The fuse byte in devices that have only a single fuse byte.
|
|
@item hfuse
|
|
The high fuse byte.
|
|
@item lfuse
|
|
The low fuse byte.
|
|
@item lock
|
|
The lock byte.
|
|
@item signature
|
|
The three device signature bytes (device ID).
|
|
@end table
|
|
|
|
The @var{op} field specifies what operation to perform:
|
|
|
|
@table @code
|
|
@itemx r
|
|
read the specified device memory and write to the specified file
|
|
|
|
@itemx w
|
|
read the specified file and write it to the specified device memory
|
|
|
|
@itemx v
|
|
read the specified device memory and the specified file and perform a verify operation
|
|
|
|
@end table
|
|
|
|
The @var{filename} field indicates the name of the file to read or
|
|
write. The @var{format} field is optional and contains the format of
|
|
the file to read or write. Possible values are:
|
|
|
|
@table @code
|
|
@itemx i
|
|
Intel Hex
|
|
|
|
@itemx s
|
|
Motorola S-record
|
|
|
|
@itemx r
|
|
raw binary; little-endian byte order, in the case of the flash ROM data
|
|
|
|
@itemx m
|
|
immediate mode; actual byte values specified on the command line,
|
|
seperated by commas or spaces in place of the @var{filename} field of
|
|
the @option{-i}, @option{-o}, or @option{-U} options. This is useful
|
|
for programming fuse bytes without having to create a single-byte file
|
|
or enter terminal mode. If the number specified begins with @code{0x},
|
|
it is treated as a hex value. If the number otherwise begins with a
|
|
leading zero (@code{0}) it is treated as octal. Otherwise, the value is
|
|
treated as decimal.
|
|
|
|
@itemx a
|
|
auto detect; valid for input only, and only if the input is not provided
|
|
at stdin.
|
|
|
|
@itemx d
|
|
decimal; this and the following formats are only valid on output.
|
|
They generate one line of output for the respective memory section,
|
|
forming a comma-separated list of the values.
|
|
This can be particularly useful for subsequent processing, like for
|
|
fuse bit settings.
|
|
|
|
@itemx h
|
|
hexadecimal; each value will get the string @emph{0x} prepended.
|
|
|
|
@itemx o
|
|
octal; each value will get a @emph{0}
|
|
prepended unless it is less than 8 in which case it gets no prefix.
|
|
|
|
@itemx b
|
|
binary; each value will get the string @emph{0b} prepended.
|
|
|
|
@end table
|
|
|
|
The default is to use auto detection for input files, and raw binary
|
|
format for output files.
|
|
|
|
Note that if @var{filename} contains a colon, the @var{format} field is
|
|
no longer optional since the filename part following the colon would
|
|
otherwise be misinterpreted as @var{format}.
|
|
|
|
As an abbreviation, the form @code{-U} @var{filename}
|
|
is equivalent to specifying
|
|
@code{-U} @emph{flash:w:}@var{filename}@emph{:a}.
|
|
This will only work if @var{filename} does not have a colon in it.
|
|
|
|
@item -v
|
|
Enable verbose output.
|
|
|
|
@item -V
|
|
Disable automatic verify check when uploading data.
|
|
|
|
@item -x @var{extended_param}
|
|
Pass @var{extended_param} to the chosen programmer implementation as
|
|
an extended parameter. The interpretation of the extended parameter
|
|
depends on the programmer itself. See below for a list of programmers
|
|
accepting extended parameters.
|
|
|
|
@item -y
|
|
Tells AVRDUDE to use the last four bytes of the connected parts' EEPROM
|
|
memory to track the number of times the device has been erased. When
|
|
this option is used and the @option{-e} flag is specified to generate a
|
|
chip erase, the previous counter will be saved before the chip erase, it
|
|
is then incremented, and written back after the erase cycle completes.
|
|
Presumably, the device would only be erased just before being
|
|
programmed, and thus, this can be utilized to give an indication of how
|
|
many erase-rewrite cycles the part has undergone. Since the FLASH
|
|
memory can only endure a finite number of erase-rewrite cycles, one can
|
|
use this option to track when a part is nearing the limit. The typical
|
|
limit for Atmel AVR FLASH is 1000 cycles. Of course, if the
|
|
application needs the last four bytes of EEPROM memory, this option
|
|
should not be used.
|
|
|
|
@item -Y @var{cycles}
|
|
Instructs AVRDUDE to initialize the erase-rewrite cycle counter residing
|
|
at the last four bytes of EEPROM memory to the specified value. If the
|
|
application needs the last four bytes of EEPROM memory, this option
|
|
should not be used.

|

@var{VALUE} can be specified using the conventional number notation of the

C programming language.
|
|
@item @samp{no_blockmode}

@chapter Terminal Mode Operation
|
|
|
|
AVRDUDE has an interactive mode called @var{terminal mode} that is
|
|
enabled by the @option{-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.

@section Terminal Mode Commands
|
|
|
|
@noindent
|
|
The following commands are implemented:
|
|
|
|
@table @code
|
|
|
|
@item dump @var{memtype} @var{addr} @var{nbytes}
|
|
Read @var{nbytes} from the specified memory area, and display them in
|
|
the usual hexadecimal and ASCII form.
|
|
|
|
@item dump
|
|
Continue dumping the memory contents for another @var{nbytes} where the
|
|
previous dump command left off.
|
|
|
|
@item write @var{memtype} @var{addr} @var{byte1} @dots{} @var{byteN}
|
|
Manually program the respective memory cells, starting at address addr,
|
|
using the values @var{byte1} through @var{byteN}. This feature is not
|
|
implemented for bank-addressed memories such as the flash memory of
|
|
ATMega devices.
|
|
|
|
@item erase
|
|
Perform a chip erase.
|
|
|
|
@item send @var{b1} @var{b2} @var{b3} @var{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.
|
|
|
|
@item sig
|
|
Display the device signature bytes.
|
|
|
|
@item part
|
|
Display the current part settings and parameters. Includes chip
|
|
specific information including all memory types supported by the
|
|
device, read/write timing, etc.
|
|
|
|
@item ?
|
|
@itemx help
|
|
Give a short on-line summary of the available commands.
|
|
|
|
@item quit
|
|
Leave terminal mode and thus AVRDUDE.
|
|
|
|
@end table
|
|
|
|
@noindent
|
|
In addition, the following commands are supported on the STK500
|
|
and STK600 programmer:
|
|
|
|
@table @code
|
|
|
|
@item vtarg @var{voltage}
|
|
Set the target's supply voltage to @var{voltage} Volts.
|
|
|
|
@item varef [@var{channel}] @var{voltage}
|
|
Set the adjustable voltage source to @var{voltage} Volts.
|
|
This voltage is normally used to drive the target's
|
|
@emph{Aref} input on the STK500 and STK600.
|
|
The STK600 offers two reference voltages, which can be
|
|
selected by the optional parameter @var{channel} (either
|
|
0 or 1).
|
|
|
|
@item fosc @var{freq}[@code{M}|@code{k}]
|
|
Set the master oscillator to @var{freq} Hz.
|
|
An optional trailing letter @code{M}
|
|
multiplies by 1E6, a trailing letter @code{k} by 1E3.
|
|
|
|
@item fosc off
|
|
Turn the master oscillator off.
|
|
|
|
@item sck @var{period}
|
|
@emph{STK500 and STK600 only:}
|
|
Set the SCK clock period to @var{period} microseconds.
|
|
|
|
@emph{JTAG ICE only:}
|
|
Set the JTAG ICE bit clock period to @var{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 to specify the
|
|
ISP clock period when operating the ICE in ISP mode.
|
|
|
|
@item parms
|
|
@emph{STK500 and STK600 only:}
|
|
Display the current voltage and master oscillator parameters.
|
|
|
|
@emph{JTAG ICE only:}
|
|
Display the current target supply voltage and JTAG bit clock rate/period.

@chapter Configuration File
|
|
|
|
@noindent
|
|
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
|
|
@code{/usr/local/etc/avrdude.conf}, while on Windows it is usally in the
|
|
same location as the executable file. The name of this file can be
|
|
changed using the @option{-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 @code{.avrduderc} within the user's home directory. On
|
|
Windows, this file is the @code{avrdude.rc} file located in the same
|
|
directory as the executable.

@noindent
|
|
Instruction formats are specified as a comma seperated 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:
|
|
|
|
@table @code
|
|
|
|
@item 1
|
|
The bit is always set on input as well as output
|
|
|
|
@item 0
|
|
the bit is always clear on input as well as output
|
|
|
|
@item x
|
|
the bit is ignored on input and output
|
|
|
|
@item a
|
|
the bit is an address bit, the bit-number matches this bit specifier's
|
|
position within the current instruction byte
|
|
|
|
@item a@var{N}
|
|
the bit is the @var{N}th address bit, bit-number = N, i.e., @code{a12}
|
|
is address bit 12 on input, @code{a0} is address bit 0.
|
|
|
|
@item i
|
|
the bit is an input data bit
|
|
|
|
@item o
|
|
the bit is an output data bit
|
|
|
|
@end table
|
|
|
|
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:
|
|
|
|
@smallexample

|
read = "1 0 1 0 0 0 0 0 x x x x x x x x",

|
|
|

The @code{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:

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 unability to write the fuse bits, the safemode
|
|
functionality does not make sense for these boot loaders.

Ensure the correct socket and routing card are mounted @emph{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
|
|
@code{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 @code{STK600-RC008T-2},
|
|
in order to use ISP mode, the jumper for @code{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
|
|
@emph{Terminal Mode}, see @ref{Terminal Mode Operation}.

@subsection Unix Installation
|
|
|
|
@noindent
|
|
To build and install from the source tarball on Unix like systems:
|
|
|
|
@example
|
|
$ gunzip -c avrdude-@value{VERSION}.tar.gz | tar xf -
|
|
$ cd avrdude-@value{VERSION}
|
|
$ ./configure
|
|
$ make
|
|
$ su root -c 'make install'
|
|
@end example
|
|
|
|
The default location of the install is into @code{/usr/local} so you
|
|
will need to be sure that @code{/usr/local/bin} is in your @code{PATH}
|
|
environment variable.
|
|
|
|
If you do not have root access to your system, you can do the the
|
|
following instead:
|
|
|
|
@example
|
|
$ gunzip -c avrdude-@value{VERSION}.tar.gz | tar xf -
|
|
$ cd avrdude-@value{VERSION}
|
|
$ ./configure --prefix=$HOME/local
|

@subsubsection FreeBSD Installation
|
|
|
|
@noindent
|
|
AVRDUDE is installed via the FreeBSD Ports Tree as follows:
|
|
|
|
@example
|
|
% su - root
|
|
# cd /usr/ports/devel/avrdude
|
|
# make install
|
|
@end example
|
|
|
|
If you wish to install from a pre-built package instead of the source,
|
|
you can use the following instead:
|
|
|
|
@example
|
|
% su - root
|
|
# pkg_add -r avrdude
|
|
@end example
|
|
|
|
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.

|
|
On rpm based linux systems (such as RedHat, SUSE, Mandrake, etc), you
|
|
can build and install the rpm binaries directly from the tarball:
|
|
|
|
@example
|
|
$ su - root
|
|
# rpmbuild -tb avrdude-@value{VERSION}.tar.gz
|
|
# rpm -Uvh /usr/src/redhat/RPMS/i386/avrdude-@value{VERSION}-1.i386.rpm
|
|
@end example
|
|
|
|
Note that the path to the resulting rpm package, differs from system
|
|
to system. The above example is specific to RedHat.

@noindent
|
|
AVRDUDE will only accept 3 Windows parallel port names: lpt1, lpt2, or
|
|
lpt3. Each of these names corresponds to a fixed parallel port base
|
|
address:
|
|
|
|
@table @code
|
|
@item lpt1
|
|
0x378

0x3BC
|
|
|
|
@end table
|
|
|
|
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.

|
|
@noindent
|
|
On Windows NT, 2000, and XP user applications cannot directly access the
|
|
parallel port. However, kernel mode drivers can access the parallel port.
|
|
giveio.sys is a driver that can allow user applications to set the state
|
|
of the parallel port pins.
|
|
|
|
Before using AVRDUDE, the giveio.sys driver must be loaded. The
|
|
accompanying command-line program, loaddrv.exe, can do just that.
|
|
|
|
To make things even easier there are 3 batch files that are also
|
|
included:
|
|
|
|
@enumerate
|
|
@item install_giveio.bat
|
|
Install and start the giveio driver.
|
|
|
|
@item status_giveio.bat
|
|
Check on the status of the giveio driver.
|
|
|
|
@item remove_giveio.bat
|
|
Stop and remove the giveio driver from memory.
|
|
@end enumerate
|
|
|
|
These 3 batch files calls the loaddrv program with various options to
|
|
install, start, stop, and remove the driver.
|
|
|
|
When you first execute install_giveio.bat, loaddrv.exe and giveio.sys
|
|
must be in the current directory. When install_giveio.bat is executed it
|
|
will copy giveio.sys from your current directory to your Windows
|
|
directory. It will then load the driver from the Windows directory. This
|
|
means that after the first time install_giveio is executed, you should
|
|
be able to subsequently execute the batch file from any directory and have
|
|
it successfully start the driver.
|
|
|
|
Note that you must have administrator privilege to load the giveio driver.

Problem: I'm using a serial programmer under Windows and get the following
|
|
error:
|
|
|
|
@code{avrdude: serial_open(): can't set attributes for device "com1"},
|
|
|
|
Solution: This problem seems to appear with certain versions of Cygwin. Specifying
|
|
@code{"/dev/com1"} instead of @code{"com1"} should help.

Problem: I'm using linux and my AVR910 programmer is really slow.
|
|
|
|
Solution (short): @code{setserial @var{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).
|
|
|
|
@code{setserial @var{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 @code{drivers/char/serial.c}.
|
|
Search the file for @code{UART_FCR_TRIGGER_8} and replace it with @code{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.
|
|
|
|
@item
|
|
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 @var{DWEN} fuse?
|
|
|
|
Solution: If the @var{DWEN} (debugWire enable) fuse is activated,
|
|
the @var{/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
|
|
@var{/RESET} pin is activated initially using a 12 V pulse (thus the
|
|
name @emph{high voltage}), so the target AVR can subsequently be
|
|
reprogrammed, and the @var{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 @var{jtag2isp} programmer type. The initial ISP
|
|
communication attempt will fail, but AVRDUDE then tries to iniate 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 @var{DWEN} fuse can be cleared.
|
|
|
|
The pin mapping for the JTAG-to-ISP adapter is:

Problem: Multiple USBasp or USBtinyISP programmers connected simultaneously are not
|
|
found.
|
|
|
|
Solution: none at this time. The simplicity of these programmers
|
|
doesn't offer a method to distinguish multiple programmers that are
|
|
connected simultaneously, so effectively only one of them is supported.
|
|
|

Problem: I cannot do @dots{} 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 @var{/RESET} line.
|
|
DebugWire mode is initiated by activating the @var{DWEN}
|
|
fuse, and then power-cycling the target.
|
|
While this mode is mainly intented 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
|
|
@emph{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.
