Approximate change log for AVRDUDE by version
|
|
|
|
----------------------------------------------------------------------
|
|
|
|
Version ???
|
|
|
|
* Now support Linux - added by "Theodore A. Roth" <troth@openavr.org>
|
|
|
|
* Now support Windows - added by "E. Weddington" <eric@umginc.net>
|
|
|
|
* Use 'configure' scripts to tailor the code to the system avrdude
|
|
is getting ready to be compiled on - added by "Theodore A. Roth"
|
|
<troth@openavr.org>
|
|
|
|
* Motorola S-Record support - submitted by "Alexey V.Levdikov "
|
|
<tsar@kemford.com>
|
|
|
|
* 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.
|
|
|
|
* 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.
|

|
|
|
|
* 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.
|
|
|
|
|
|
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
