$Id$ Approximate change log for AVRDUDE by version. (For more detailed changes, see the ChangeLog file.) ---------------------------------------------------------------------- Version TBD * Add support for the Bascom SAMPLE programmer. Submitted by Larry Barello 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
