(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: + -

Submitted by + Jan-Hinnerk Reichert <jan-hinnerk_reichert@hamburg.de>. + + * Perform an auto erase before programming if the flash memory is + anywhere specified to be written by any of the -U requests.

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 <ashepherd@wave.co.nz>. + + * 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 <rune.christensen@adslhome.dk>. + + * Add support for the sp12 programmer.

Weddington" <eric@ecentral.com>. + + * 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. + + * 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 <rick@KIWI-Computer.com>. + + * 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. |
