GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

* bootstrap: autoconf 2.62 works well.
2010-01-12 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
Various fixes for Xmega devices.
* avrdude.conf.in: Correctly declare EEPROM page sizes for
all Xmega devices (0x20 instead of 0x100).
* avr.c: If a memory region has a page size declared, try
using the paged IO routines regardless of the target memory
name. Xmega EEPROM requires to be written in paged mode.
Correctly use a long (rather than unsigned long) variable to
evaluate the success status of the paged mode write attempt.
* stk500v2.c: Don't apply TIF space offsets twice (bug #27995:
AVRDUDE 5.8svn fails to program and read XMEGA); use
stk500v2_loadaddr() prior to paged mode (EEPROM and flash) writes,
otherwise programming of flash areas will fail; while being there,
check the return value of stk500v2_loadaddr() everywhere; use the
correct write/erase mode bits (same as AVR Studio does).
2010-01-12 Michal Ludvig <mludvig@logix.net.nz>
* buspirate.c: Initialise firmware version to v0.0
prior to parsing the buspirate banner.
2010-01-11 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
Clean-up the Xmega erase functions.
* jtagmkII_private.h: Add CMND_XMEGA_ERASE as well as
the various XMEGA_ERASE_* definitions (from updated
appnote AVR067)
* jtagmkII.c (jtagmkII_chip_erase): Correctly implement Xmega chip
erase based on CMND_XMEGA_ERASE. After erasing an Xmega part, do
*not* reinitialize the world, as a subsequent programming
operation will fail (for unknown reasons). Actually, this was
really only required for ancient AVRs, but doesn't hurt on mega
and tiny devices.
* jtagmkII.c (jtagmkII_pre_write): Remove, this turned out
to be just a chip erase.
* jtagmkII.c (jtagmkII_program_disable): Don't try reading
"hfuse" for Xmega parts; they don't have it.
* main.c (main): Re-enable auto-erase. It's been done
before (as "jtagmkII_pre_write") in jtagmkII_paged_write()
anyway. Xmega boot and application flash areas should be
handled separately in the future, so auto_erase can only
affect the area just being programmed.
2010-01-11 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
* main.c (main): disable safemode for Xmega parts.
2010-01-12 Michal Ludvig <mludvig@logix.net.nz>
* buspirate.c: If the BusPirate doesn't respond
to a standard a reset command assume it was in binmode
and attempt to exit to text mode first.
2010-01-08 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
* bitbang.c: Fix Win32 build error: move freq up to the file
level.
* buspirate.c: Fix Win32 build warning: include <malloc.h> to
to get a declaration for alloca().
2010-01-08 Thomas Fischl <tfischl@gmx.de>
bug #28520: Programming with USBasp with low clock speed fails
* usbasp.c: Change blocksize depending on sck frequency to
avoid usb transmition timeouts.
2010-01-08 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
bug #27505: serbb_posix does not cope with inverted pins
* serbb_posix (serbb_highpulsepin): apply PIN_MASK when
checking pin numbers.
* serbb_win32 (serbb_highpulsepin): (Dito.)
2010-01-08 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
bug #28516: Linux/Dragon: Error message on exit
* stk500v2.c: Fix the "bad response to GO command:
RSP_ILLEGAL_EMULATOR_MODE" message. jtagmkII_close()
has been called with the wrong pgm->cookie. Wrap it
inside stk500v2_jtagmkII_close(), adjusting the cookie
data appropriately.
2010-01-08 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
Submitted by Doug:
patch #7010: Win32 enhanced bitbang_delay
* bitbang.c (bitbang_calibrate_delay, bitbang_delay): On Win32,
use the high-resolution performance counter rather than the
uneducated delay loop guess if it is available on the target
hardware.
2010-01-08 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
Submitted by Gerard:
patch #6828: Using arbitrary BAUD rates
* ser_posix.c (serial_baud_lookup): Allow non-standard baud
rates.

Submitted by Gyorgy Szekely:
bug #28458: Buffer line is incorrectly released for PP programmers
* par.c (par_close): use par_setmany() rather than par_setpin()
for PPI_AVR_BUFF.
2010-01-07 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
Submitted by Lukasz Goralczyk:
bug #27507: SIGSEGV when using avrdragon (avrdude 5.8)
* stk500v2.c (stk500v2_dragon_isp_initpgm): Use
stk500v2_jtagmkII_setup/stk500v2_jtagmkII_rather than their
jtagII counterparts, to get the private data properly
initialized.
2010-01-07 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
* buspirate.c: Cosmetics: remove UTF-8 dashes, adjust for 8-column
hard tabs.
2010-01-07 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
* buspirate.c: add $ Id $ line.
* buspirate.h: add $ Id $ line.
2010-01-07 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
Fix a few warnings that came up recently (some of them only triggered
by recent GCC versions).
* config_gram.y (parse_cmdbits): "brkt possibly used uninitialized"
(GCC errs here)
* jtagmkII.c (jtagmkII_reset32): "status possibly used uninitialized"
(I think GCC errs, too)
* buspirate.c: "pointers differ in signedness" (mismatch between
string processing and the use of "unsigned char" throughought the
AVRDUDE API)
2010-01-01 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
* jtagmkII.c (jtagmkII_smc_init32): replace sleep() by usleep() for
win32 compatibility.

Make the BUFF pin a mask like VCC to allow multiple pins to be
asserted at the same time (STK200 has two buffer enable lines).
Add the STK200 programmer.
Fix EEPROM address line selection for several parts.
2001-12-15 Brian S. Dean <bsd@bsdhome.com>

2001-11-24 Brian S. Dean <bsd@bsdhome.com>
* Makefile:
Change "WARNING" to "NOTE" when overwriting the avrprog.conf file.
* avrdude.1: Add my e-mail address.
* avrdude.conf.sample:
Add comments about instruction formats. Correct an instruction
specification (cut&paste error).
2001-11-21 Brian S. Dean <bsd@bsdhome.com>
* avr.c, config_gram.y, lexer.l, term.c:
In interactive mode, reset the address and length if we start dumping
a memory type different than the previous one.
* avr.c, avrdude.conf.sample, config_gram.y:
Allow instruction data to be specified more flexibly, which can be
used to make the instruction input more readable in the config file.
* main.c: Bump version number.
* Makefile, avr.c, avr.h, avrdude.conf.sample, config.c, config.h:
* config_gram.y, fileio.c, fileio.h, lexer.l, main.c, term.c:
This is a major re-write of the programming algorithms. The Atmel
serial programming instructions are not very orthoganal, i.e., the
"read fuse bits" instruction on an ATMega103 is an entirely different
opcode and data format from the _same_ instruction for an ATMega163!
Thus, it becomes impossible to have a single instruction encoding
(varying the data) across the chip lines.
This set of changes allows and requires instruction encodings to be
defined on a per-part basis within the configuration file. Hopefully
I've defined the encoding scheme in a general enough way so it is
useful in describing the instruction formats for yet-to-be invented
Atmel chips. I've tried hard to make it match very closely with the
specification in Atmel's data sheets for their parts. It's a little
more verbose than what I initially hoped for, but I've tried to keep
it as concise as I could, while still remaining reasonably flexible.
2001-11-19 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avr.h, avrdude.conf.sample, main.c, ppi.c, term.c:
Add support for ATMega163.
Add support for reading/writing ATMega163 lock and fuse bits.
Unfortunately, in looking at the specs for other ATMega parts, they
use entirely different instruction formats for these commands. Thus,
these routines won't work for the ATMega103, for example.
Add support for sending raw command bytes via the interactive terminal
interface. This allows one to execute any programming instruction on
the target device, whether or not avrprog supports it explicitly or
not. Thus, one can use this feature to program fuse / lock bits, or
access any other feature of a current or future device that avrprog
does not know how to do.
Add in comments, an experimental instruction format in the
configuration file. If this works out, it would allow supporting new
parts and non-orthoganal instructions across existing parts without
making avrprog code changes.
2001-11-17 Brian S. Dean <bsd@bsdhome.com>
* avrdude.conf.sample: Add ATMEGA163 part.
2001-11-11 Brian S. Dean <bsd@bsdhome.com>
* main.c: output formatting
2001-11-05 Brian S. Dean <bsd@bsdhome.com>

2001-10-31 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avrdude.conf.sample, main.c: Correct version string.
Update read/write status more frequently.
Prefix ATMega parts with an 'm'.
2001-10-16 Brian S. Dean <bsd@bsdhome.com>
* avr.c: Change ording for memory display.
* config_gram.y: comment
* avr.c, avr.h, avrdude.conf.sample, config_gram.y, lexer.l, term.c:
Fix (again, hopefully) page addressing for the ATMega parts.
Rename the poorly chosen name "bank" to "page" for page addressing.
Atmel calls it "page" in their documentation.
* config_gram.y, main.c: Fix an (non)exit.
Silence a couple of compiler warnings.
* avr.c, avr.h, avrdude.conf.sample, config_gram.y, main.c:
Fix ATMega flash addressing. Add an ATMEGA16 part. Perform sanity
checking on the memory parameters for parts that do bank addressing.
2001-10-15 Brian S. Dean <bsd@bsdhome.com>
* config.c, config.h, lists.h: Add copyright.
* config_gram.y, lexer.l, lists.c: Add copyrights.
* Makefile: Attempt to install avrprog.conf.
* avrdude.conf.sample: Correct dt006 pinout.
* Makefile, lexer.l:
Try and detect an old-style config file and print an appropriate error
message and a suggestion for correcting it.
* Makefile, avr.c, avrdude.1, avrdude.conf.sample: Update the man page.
Miscellaneous minor cleanups.
2001-10-14 Brian S. Dean <bsd@bsdhome.com>
* Makefile, Makefile.inc, avr.c, avr.h, avrdude.conf.sample:
* config.c, config.h, config_gram.y, lexer.l, lists.c, lists.h:
* main.c, pindefs.h, term.c:
Use lex/yacc for parsing the config file. Re-work the config file
format using a more human-readable format.
Read part descriptions from the config file now instead of hard-coding
them.
Update usage().
Cleanup unused code.
* Makefile, avr.c, avr.h, fileio.c, term.c:
First cut at supporting the ATmega 103 which uses bank addressing and
has a 128K flash.
Due to the bank addressing required, interactive update of the flash
is not supported, though the eeprom can be updated interactively.
Both memories can be programmed via non-interactive mode.
Intel Hex Record type '04' is now generated as required for outputing
memory contents that go beyond 64K.
2001-10-13 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avr.h, fileio.c, fileio.h, main.c, ppi.c, ppi.h, term.c:
* term.h:
Style fixes.
* avr.c, avr.h, fileio.c, fileio.h, main.c, term.c:
Commit changes in preparation for support the ATMega line.
2001-10-01 Brian S. Dean <bsd@bsdhome.com>
* Makefile: Don't override CFLAGS.
* avrdude.1: Correct default pin assignment.
* avr.c, fileio.c, main.c, ppi.c, term.c:
Remove debugging code - it served its purpose.
Update copyrights.
2001-09-21 Brian S. Dean <bsd@bsdhome.com>
* main.c:
Be sure to read the exit specs after the pin configuration has been
assigned, otherwise, we may apply the exit specs to the wrong pins.
* main.c: debugging
2001-09-20 Brian S. Dean <bsd@bsdhome.com>
* avrdude.1, avrdude.conf.sample, main.c:
Prefix pin config entries in the config file with a "c:". Later, I
might make part descriptions read in this way and we can use a
different letter for those (p). This will make the parsing easier to
distinguish between the entry types.
* main.c: Initialize pin configuration description.
2001-09-19 Brian S. Dean <bsd@bsdhome.com>
* AVRprog.pdf, Makefile, avr.c, avrdude.1, avrdude.conf.sample:
* avrdude.pdf, fileio.c, fileio.h, main.c, pindefs.h, term.c:
Make the pin definitions configurable based on entries in a config
file. This makes supporting other programmers much easier.
Rename AVRprog.pdf to avrprog.pdf.
2001-04-29 Brian S. Dean <bsd@bsdhome.com>
* avrprog-programmer.jpg: Remove this image file from the repository.
2001-04-26 Brian S. Dean <bsd@bsdhome.com>
* avrprog-schematic.jpg:
Remove this image, use AVRprog.pdf as the preferred schematic for the
programmer.
2001-04-25 Brian S. Dean <bsd@bsdhome.com>
* AVRprog.pdf, Makefile, avrdude.1:
Add a schematic provided by Joerg Wunch and also update the manual
page (also updated by Joerg) to reference the schematic.
2001-02-25 Brian S. Dean <bsd@bsdhome.com>
* Makefile, Makefile.inc: Automate dependency generation.
2001-02-08 Brian S. Dean <bsd@bsdhome.com>
* main.c: Turn off ready led when finished programming.
* main.c: update version
* avr.c, main.c: Correct a few comments.
* Makefile, avr.c, term.c: Makefile : update dependencies
avr.c : correct status led updates
term.c : update status leds on write, make the address and length
arguments for dump optional.
2001-01-26 Brian S. Dean <bsd@bsdhome.com>
* main.c: Version 1.1
* main.c:
Hmmm ... cvs co -D <timestamp> does not work. Change the revision
timestamp to a full date/time value.
* avr.c, fileio.c, main.c, ppi.c, term.c:
Add a -V option to display the version information about each
component module. This is intended for support purposes, so that I
can tell unambiguously what version a binary out in the field is.
Additionally, display a revision timestamp along with the version
number. This also is intended for aiding in support and is the Unix
time of the latest component module. Having this, should allow me to
do a "cvs co -D timestamp avrprog" and get exactly the source of the
version that is being reported.
* fileio.c:
Return the maximum address (+1) written as opposed to the actual
number of bytes written. The presence of an Intel Hex address
record can cause these two number to be different; but the callers
of this routine need the former.
* main.c:
Fix a place where we were exiting without applying the exit-specs.
Wrap a long line.
* avr.c, fileio.c: avr.c: Update a comment.
fileio.c: Properly handle all the Intel Hex record types that I can
find information about.
2001-01-25 Brian S. Dean <bsd@bsdhome.com>
* Usage, avr.h: Get rid of the Usage file.
2001-01-24 Brian S. Dean <bsd@bsdhome.com>
* Makefile, avr.c, avr.h, main.c, pindefs.h, ppi.c:
Move pin definitions to their own file.
First pass at providing feedback via the optionally connected leds. I
don't actually have any of these attached to my programmer, so I can
only guess as whether this is toggling them on and off correctly.
Also, enable and disable the optional 74367 buffer.
* avr.h, main.c, ppi.c, ppi.h, avr.c:
Rearrange the pinout for the programmer to be a little more logical.
Provide hooks to support a buffered programmer, pin 6 is now used to
enable a buffer that can be used to isolate the target system from the
parallel port pins. This is important when programming the target
in-system.
Totally change the way the pin definitions are defined. Actually
set/clear pins based on the way more intuitive pin number, instead of
PPI data register, bit number combination. A table of pin data is
used so that any hardware inversion done by the parallel port is
accounted for, what you set is actually what appears at the pin.
Retain the old method for handling Vcc, however, because the hold
method is much easier to use when setting / retrieving multiple pins
simultaneously.
2001-01-22 Brian S. Dean <bsd@bsdhome.com>
* Makefile: Don't gzip the man page.
* avrdude.1: .Nm macro fix. Submitted by Joerg.
* main.c: Cosmetic, don't output a preceding linefeed for usage().
* Makefile, avr.c, avr.h, fileio.c, term.c:
Makefile : use gzip -f for man page installation so that we don't get
prompted.
avr.c avr.h fileio.c term.c :
Change the avrpart data structure so that the typedef AVRMEM is
used as an index into an array for the sizes of the memory types
and also for pointers to buffers that represent the chip data for
that memory type. This removes a lot of conditional code of the
form:
switch (memtype) {
case AVR_FLASH :
...
}
Also, re-code avr_read_byte() and avr_write_byte() to properly
handle the flash memory type without having to tell them whether
they should program the high byte or the low byte - figure that
out from the address itself. For flash memory type, these
routines now take the actual byte address instead of the word
address. This _greatly_ simplifies many otherwise simple
operations, such a reading or writing a range of memory, by not
having to worry about whether the address starts on an odd byte
or an even byte.
2001-01-20 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avr.h, fileio.c, fileio.h, main.c:
Return error codes instead of exiting, thus making sure that we exit
only via main() so that the exitspecs are properly applied.
When reading input data from a file, remember how many bytes were read
and write and verify only that many bytes.
Don't complain when an input file size is smaller than the memory size
we are programming. This is normal.
* fileio.c:
Correct checksum calculation; failure to account for the value of the
record type was causing non-zero record types to be calculated
incorrectly.
* Makefile, main.c: Makefile : install the man page
main.c : drop the giant usage text now that we have a man page.
* avrdude.1:
Add initial man page graciously contributed by Joerg Wunsch. Thanks
Joerg!
2001-01-19 Brian S. Dean <bsd@bsdhome.com>
* term.c:
Accept abbreviations for eeprom and flash for the dump and write
commands.
Fix small bug keeping 1 character command lines from being added to
the history.
* term.c:
Implement enough state in cmd_dump so that if it is called with no
arguments, it successively dumps the next chunk of data of the same
previously specified length.
* term.c, term.h, fileio.c, fileio.h, main.c, ppi.c, ppi.h:
* Makefile, avr.c, avr.h, avrprog.c:
The program was getting too large for a single file. Split it up into
more modular pieces.
Also, accept command abbreviations as long as they are not ambiguous.
* avrprog.c:
Add ability to specify the state of the power and reset pins on
program exit. Default to leaving the pins in the state they were when
we found them.
Contributed by: Joerg Wunsch
2001-01-18 Brian S. Dean <bsd@bsdhome.com>
* Makefile, avrprog.c:
Switch to using readline() for getting terminal input. I can't seem
to get the history capabilities working yet, but even so, it does
better handling of the prompt and strips newlines for us, so it's
still a win.
Add a few new commands for terminal mode: help, sig, part, erase.
Display rudimentory help using the help command.
Add some function prototypes.
* Usage, avrprog.c:
Change -c (interactive command mode) to the more intuitive -t
(terminal mode).
Make binary format the default for output.
Update the parts table with corrections for old values and add some
new values.

Prepare the Makefile for integration into the FreeBSD ports tree.
Fix a few "may be used uninitialized" bugs found by -Wall.
2001-01-14 Brian S. Dean <bsd@bsdhome.com>
* avrprog.c: Free a buffer.
* avrprog.c:
Use a smarter programming algorithm - read the existing data byte
first and only write the new one if it is different.
Add -n option which is a test mode in which the chip is not actually
updated. This option does not affect writes in interactive mode.
* avrprog.c: Add the "dump" and "write" interactive commands.
* avrprog.c:
Correctly produce and handle "end of record" for intel hex files.
2001-01-13 Brian S. Dean <bsd@bsdhome.com>
* avrprog.c:
Re-enable writing to the chip. I should probably should make this a
command-line selectable option so that I don't keep forgetting and
committing it with it disabled.
* avrprog.c:
Add a newline before exiting due to command line errors. Perform a
bit more option compatibility testing between -c, -i, and -o.
* avrprog.c: Add input file format auto-detection support.
* Usage, avrprog.c: Say what the defaults are.
* avrprog-programmer.jpg, Usage, avrprog-schematic.jpg: New files.
* avrprog.c: Correct usage text.
* avrprog.c:
Parameterize a few additional items per chip. Print out all per-chip
parameters on startup. Use the per-chip parameters in the code
instead of hard-coded values for the 2313.
* avrprog.c: Fix filename assignment error.
Clean up debugging code a little, utilize fileio() instead of making
direct calls to b2ihex().
* avrprog.c: A lot of general code cleanup.
Re-work command line options to be more intuitive.
Support Intel Hex input and output file formats. Provide hooks to
support Motorola S-Record as well.
Add a few more part-specific parameters to the avrpart structure.
Only write the flash or eeprom if the data to be written is not 0xff.
2000-12-31 Brian S. Dean <bsd@bsdhome.com>
* avrprog.c: Update a comment.
* avrprog.c:
Provide the ability to tie additionally tie pins 6-9 of the parallel
port to Vcc in order to supply more current.
Fix a typo on the size of the S1200's Flash.
Bring RESET low when programming is completed.
* avrprog.c:
Correct pin connection comments. Elaborate a bit on Vcc connection.
* avrprog.c:
Update after receiving some good feedback from Joerg Wunsch. We
should now be able to program AT90S1200's.
2000-12-30 Brian S. Dean <bsd@bsdhome.com>
* avrprog.c: Don't limit eeprom addresses.
2000-12-20 Brian S. Dean <bsd@bsdhome.com>
* Makefile, avrprog.c:
Add support for the 8515. Make the addition for other devices easier.
2000-08-27 Brian S. Dean <bsd@bsdhome.com>
* avrprog.c:
Clear all bits except AVR_RESET when finished reading or programming
the Atmel device.
2000-08-07 Brian S. Dean <bsd@bsdhome.com>
* avrprog.c: update announcement message
* avrprog.c: Update announcement message.
* avrprog.c: Return the correct return code from 'main()'.
* avrprog.c:
Add ppi_pulse() function and fix ppi_toggle() to actully toggle
instead of pulse.
Make all abnormal returns after the parallel port has been opened go
through a single exit point at the bottom of 'main()'.
2000-08-06 Brian S. Dean <bsd@bsdhome.com>
* Makefile, avrprog.c: Makefile: add --pedantic compiler option
avrprog.c:
Add lots of comments, move getop() variable declarations to
the top of the program.
Add a typedef name to the AVR memory type and use it for
function declarations.
Add a usleep() delay in the sense loop to avoid becoming a cpu
hog.
Print out a version string so that folks know what version of
the software they are running.
Be sure and close the parallel device and the i/o file when
terminating abnormally.
* avrprog.c: Print out version information when invoked.

avrprog.c:
Add license.
Document the header a bit better.
Add capability to read out and display the device signature bytes.
Add capability to power the device from the parallel port.
Eliminate debug print facility.
Provide 'avr_cmd()' function.
When memory locations don't program, generate a newline so that the
information is not overwritten and lost.
Don't print out the message about needing to specify a file if the
user is not requesting an operation that requires the file.
2000-08-05 Brian S. Dean <bsd@bsdhome.com>

2002-12-07 Brian S. Dean <bsd@bsdhome.com>
* avrdude.1, main.c:
If the stk500 is being used, default to using the first serial port.
2002-12-03 Brian S. Dean <bsd@bsdhome.com>
* avrdude.1: Mention STK500 support.
2002-12-01 Brian S. Dean <bsd@bsdhome.com>
* stk500.c: Remove unused code.
* CHANGELOG, stk500.c:
Document changes since the previous version in the CHANGELOG.
Cleanup stk500.c a bit.
* stk500.c: Fix cut and paste braino.
* avr.c, avrdude.conf.sample, main.c, pgm.h, stk500.c:
The STK500 can perform paged read/write operations even on standard
"non-paged" parts. Take advantage of that and use the faster internal
routines of the STK500 for those parts as well.
* avr.c, avr.h, avrpart.h, main.c, pgm.c, pgm.h, stk500.c:
Optimize reading and writing for the STK500 programmer if the part
supports paged reads and writes. This greatly decreases the
program/verify time from about 4.5 minutes down to about 10 seconds in
a 12K program size test case.
Print out the hardware and firmware version for the STK500 if verbose
is enabled.
* avrdude.conf.sample, avrpart.h, config_gram.y, lexer.l, pgm.h:
* ppi.c, ppi.h, stk500.c, stk500.h, stk500_private.h:

* avr.c, avr.h:
Seperate programmer operations out into a driver-like interface so
that programmers other than the direct parallel port connection can be
supported.
2002-11-23 Brian S. Dean <bsd@bsdhome.com>
* CHANGELOG, main.c, term.c:
term.c - 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.
CHANGELOG - describe changes
main.c - update version number
* main.c:
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.
2002-11-06 Brian S. Dean <bsd@bsdhome.com>
* CHANGELOG: Update changelog.
* avr.c, avr.h, main.c: Fix -Y option. Reported by Joerg Wunsch.

* CHANGELOG, main.c: Version update and CHANGELOG entry.
* avr.c:
Be backward compatible with the 2-byte rewrite cycle counter which
appeared in version 2.1.0, but was changed to a 4 byte counter in
version 2.1.1. Reminded by Joerg Wunsch.
2002-10-29 Brian S. Dean <bsd@bsdhome.com>

* Makefile: Remove --pedantic and -g from the compiler options.
2002-10-11 Brian S. Dean <bsd@bsdhome.com>
* avr.c, term.c:
Use a four byte value instead of a two byte value for the programming
cycle count stored at the end of EEPROM. It seems as though Atmel was
greatly conservative in claiming a 1000 count reliability for the
FLASH. I current have a part that has been reprogrammed 173330 times,
and counting.
Fix a compiler warning.
* avrdude.conf.sample:
Fix ATMega128 instruction encoding for reading the low and high fuse
bits. Thanks to Joerg Wunsch for tripping over this.
2002-08-01 Brian S. Dean <bsd@bsdhome.com>
* avr.c, avrdude.1, main.c:
Move erase-rewrite cycle increment to within the chip erase routine so
that it is tracked no matter where the erase was initiated: command
line mode or interactive mode, without code duplicaiton.
* CHANGELOG: Recent updates.
* avr.c: Eliminate unused variables.
* avr.c, avr.h, avrdude.1, fileio.c, main.c:
Implement a way of tracking how many erase-rewrite cycles a part has
undergone. This utilizes the last two bytes of EEPROM to maintain a
counter that is incremented each time the part is erased.
2002-07-27 Brian S. Dean <bsd@bsdhome.com>
* avr.c, main.c:
Fix a typo in a comment. Display the size of memory being written.

* main.c, term.c:
Fix error reporting by avr_write_byte().
Fix setting of status LEDs under various write-fail conditions.
Add a flag to indicate that a memory type requires the device to
possibly be powered off and back on after a write to it. This is due

and turn stderr into unbuffered output while producing the
progress report.
2007-11-07 Joerg Wunsch <j@uriah.heep.sax.de>

2007-05-16 Joerg Wunsch <j@uriah.heep.sax.de>
* avrdude.conf.in: Fix AVR910 devcodes. It seems that the AVR109
listing refers to "BOOT"-type code, while the standard codes are
different (usually one below).
2007-05-16 Joerg Wunsch <j@uriah.heep.sax.de>
* avr.c (avr_read, avr_write): only use the paged_load and
paged_write backend functions iff the memory area in question has
a page_size != 0.

programmer
2007-05-15 Colin O'Flynn <coflynn@newae.com>
* avrdude.conf.in: Rename the ATmega164 and ATmega324 into
ATmega164P and ATmega324P, resp. Add an entry for the ATmega644P.
Fixes bug #19769: ATmega164p not recognized
2007-05-15 Joerg Wunsch <j@uriah.heep.sax.de>
* ser_posix.c (ser_send): Don't select() on the output fd before
trying to write something to the serial line. That kind of
polling isn't very useful anyway, and it seems it breaks for the
Linux CP210x USB<->RS-232 bridge driver which is certainly a bug
in the driver, but we can just avoid that bug alltogether.
2007-05-15 Joerg Wunsch <j@uriah.heep.sax.de>
* avrdude.conf.in: Fix the STK500v2 ISP delay parameter for
ATmega640/1280/1281/2560/2561. Atmel has changed the XML
files after the initial release.
2007-05-01 Colin O'Flynn <coflynn@newae.com>
* safemode.c: -Oops - bug in verbose output. Fixed.
-Fixed handling of cases where programmer cannot read fuses (AVR910)
* main.c: -Also fixing handling of cases where programmer cannot
read fuses
This should close one or more bugs (18803, 19570)
2007-05-01 Colin O'Flynn <coflynn@newae.com>
* safemode.c: Added verbose output from safemode routines.
2007-03-25 Colin O'Flynn <coflynn@newae.com>
* stk500generic.c: Forgot to close the serial port before trying to
open it again, caused problems on Windows machines.
Closes bug #19411
2007-02-26 Joerg Wunsch <j@uriah.heep.sax.de>

distcheck" will include the documentation into the tarball even if
the configure had been run without the --enable-doc.
2007-01-30 Joerg Wunsch <j@uriah.heep.sax.de>

* usbasp.c: (Ditto.)
2007-01-29 Joerg Wunsch <j@uriah.heep.sax.de>
* avrpart.c: More backend/library abstraction and generalization:
turn the list_parts() and list_programmers() functions into
general list iteration functions that call a caller-supplied
callback for each element. Implement list_parts() and
list_programmers() as private functions in main.c based on that
approach.
* avrpart.h: (Ditto.)
* main.c: (Ditto.)
* pgm.c: (Ditto.)
* pgm.h: (Ditto.)
2007-01-25 Joerg Wunsch <j@uriah.heep.sax.de>

now.
2007-01-24 Joerg Wunsch <j@uriah.heep.sax.de>
Major code cleanup.

and EEPROM, based on the current Atmel XML file.
2007-01-12 Joerg Wunsch <j@uriah.heep.sax.de>

and the presence of the header ddk/hidsdi.h. It now works
correctly under Cygwin and several flavours of MinGW.
* Makefile.am: Add new LIBHID pattern.
2007-01-11 Joerg Wunsch <j@uriah.heep.sax.de>
* butterfly.c (butterfly_initialize): when sending the 'T'
command (which is ignored by current AVR109 bootloaders),
send the first reply from the list of supported device
codes back rather than using avrdude.conf's idea about
an AVR910 device code. Apparently, this solves disagreements
between different versions of at least the ATmega8 AVR910
device code.
Closes bug #18727: Writing flash failed
2007-01-07 Joerg Wunsch <j@uriah.heep.sax.de>
Reported by Till Harbaum:
* avrdude.conf.in (ATtiny25/45/85): Change HVSP reset from
500 microseconds to 1 ms, matching the most recent Atmel XML
specs.

Submitted by limor <limor@ladyada.net>
* usbtiny.c (usbtiny_cmd): Replace sizeof() by a fixed constant
4 for the result array, because otherwise it would take the size
of a pointer which miserably fails on 64-bit machines.
2008-11-05 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
patch #6609: Using PCI parallel port cards on Windows

-p option is neither lpt1/2/3, try interpreting it directly as
a base address.

the expected 0 for success rather than a protocol-dependant
number.
2008-11-04 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
bug #22883: Chip Erase performed even with no-write flag (-n)
* main.c: Do not erase the chip if both, -e and -n options have

signature for AT90USB646/647. Alas, the datasheet has never been
corrected for years.

* jtagmkII.c: Fix a serious memory corruption that happened when
using the JTAG ICE mkII (or AVR Dragon) in ISP mode. The wrong
set of per-programmer private data had been allocated (stk500v2
vs. jtagmkII) which was too small to hold the actual data.

allow to continue with -F if it failed yet do not attempt to
perform anything on the device itself. That way, -tF could be
specified for programmers like the STK500/STK600 even without a
device connected, just in order to allow changing parameters on
the programmer itself.

corruption.
2008-07-27 Joerg Wunsch <j.gnu@uriah.heep.sax.de>
First implementation of ATxmega support. By now, only the
PDI mode of the STK600 is supported. Single-byte EEPROM
(and flash) updates do not work yet.

operations, besides "flash" and "eeprom".
* avrdude.conf.in: add ATxmega128A1 and ATxmega128A1revD
* avrpart.h: add the AVRPART_HAS_PDI flag (used to distinguish
ATxmega parts from classic AVRs), the nvm_base part field, and
the offset field for a memory region.
* config_gram.y: add "has_pdi", "nvm_base", and "offset"
* lexer.l: (Ditto.)
* main.c: disable auto_erase for ATxmega parts
* stk500v2.c: implement the XPROG functionality, and divert to

- 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 <matthias@matwei.de>
* Add ATmega64 support.
Contributed by: Erik Christiansen <erik@dd.nec.com.au>
* Improved polling algorithm to speed up
programming of byte oriented parallel programmers.
Contributed by: Jan-Hinnerk Reichert <jan-hinnerk_reichert@hamburg.de>
* 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 <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. 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 <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. Submitted by
Larry Barello <larryba@barrello.net>.
Version 4.1.0
* Add support for the Bascom SAMPLE programmer. Submitted by
Larry Barello <larryba@barrello.net>.
* 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" <troth@openavr.org>.
* Now support Windows - added by "Eric B. 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.

- Man page needs updated for avr910 info.
- Website needs to link to docs:
http://savannah.nongnu.org/download/avrdude/doc/avrdude-html/
- Add "skip empty pages" optimization on avr910 paged write. The stk500 has
this optimization already.
- Fix "overfull \hbox" issues in building documentation.
- FIXME: term.c: terminal_get_input(): strip newlines in non-readline input
code.
- FIXME: avr910.c: avr910_cmd(): Insert version check here.
- FIXME: ser_posix.c: serial_close(): Should really restore the terminal to
original state here.
- FIXME: main.c, par.c: exitspecs don't work if RESET-pin is controlled over
PPICTRL.
- transfer ppi-speedtuning to the windows version (CAVEAT: This will make
programming too fast for chips with 500kHz clock)
- make SCK-period configurable for PPI-programmers
