$Id$ Approximate change log for AVRDUDE by version. (For more detailed changes, see the ChangeLog file.) ---------------------------------------------------------------------- Current: * Add support for the AVR Dragon (JTAG and ISP mode). Version 5.2: * New devices supported: - AT90USB646/647/1286/1287 - ATmega2560/2561 - ATmega325/3250/645/6450 - ATtiny11 (HVSP only device) - ATtiny261/461/861 * Fixed paged flash write operations for AT90PWMx devices (error in datasheet). * Add signature verification. * Add high-voltage mode programming for the STK500 (both, parallel, and high-voltage serial programming). * Add support for using the JTAG ICE mkII as a generic ISP programmer. * Allow for specifying the ISP clock delay as an option for bit-bang programming adapters. * Add support for Thomas Fischl's USBasp low-cost USB-attached programmer. * The "stk500" programmer type is now implemented as a stub that tries to probe for either "stk500v1" or "stk500v2". * Many bugfixes. Version 5.1: * New devices supported: - ATmega640/1280/1281 - ATtiny24/44/84 * JTAG mkII support now works with libusb-win32, too * JTAG ICE mkI support has been added * Solaris support has been added (including ecpp(7D) parallel-port bit-bang mode) Version 5.0: * Support for JTAGICE MkII device * Support for STK500 Version 2 Protocol * New devices supported: - AT90CAN128 - ATmega329x/649x - ATmega164/324/644 - AT90PWM2/3, - ATmega164/324/644 - ATmega329x/649x - ATtiny25/45/85 * Support for serial bit-bang adapters: Ponyprog serial, UISP DASA, UISP DASA3. * DAPA programmer pinout supported * New "safemode" feature where fuse bits are verified before exit and if possible recovered if they have changed. This is intended to protect against changed fuses which were not requested which is reported to sometimes happen due to improper power supply or other reasons. * Various fixes for avr910 and butterfly programmers * Full support for AVR109 boot loaders (butterfly) * Adding -q -q suppresses most terminal output Version 4.4.0: * Native Win32 support: The windows build doesn't need Cygwin anymore. Additionally, the delay timing on windows should be more accurate now. 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.
