# $Id$
Summary of changes since AVaRICE 2.14
==================================
. patch #39 Compilation error in jtag3io.cc: (avarice 2.14)
. patch #40 Remove old style exception throw specifier
(bug #34 AVaRICE 2.14 won't compile on Arch Linux)
Summary of changes in AVaRICE 2.14
==================================
. Replace the USB daemon by Posix threads (bug #15).
. Implement JTAGICE3 handling
. Implement Atmel-ICE handling, including JTAGICE3 with firmware
version 3.x, EDBG and mEDBG integrated debuggers
. Implement the GDB 7+ flash write protocol (for the "load" command)
. Implement a backend command for the GDB "monitor" command; by
now, this is mostly a stub, but "monitor help" and "monitor
version" are already around.
. New devices: ATmega256RFR2, ATmega2564RFR2, ATmega128RFR2,
ATmega1284RFR2, ATmega64RFR2, ATmega644RFR2, ATxmega64A3
. Bugfix: support software breakpoints on ATmega48P, ATmega88P,
ATmega168P, ATmega328P, ATtiny24, ATtiny44, ATtiny84
Summary of changes in AVaRICE 2.13
==================================
. Rearrange the entire error handling to use exceptions, rather than a
mix between error code returns, and prematurely exiting the program
from deep inside, without any attempt to cleanup the JTAG ICE
connection status. This is a lot cleaner now, with a much reduced
chance to leave the ICE in an unworkable state when exiting the
program.
. New devices: ATxmega128B1, ATxmega128B3, ATxmega64B1, ATxmega64B3,
ATmega16M1, ATmega64M1, ATmega64C1, ATxmega128A3, ATxmega32A4
. Deprecate target programming (downloading) from the ELF file. It
must be explicitly enabled now by the --enable-target-programming
configure option. If not enabled, AVaRICE no longer depends on
libbfd and its prerequisites. Use AVRDUDE for device programming.
. Added IO register definitions (for GDB's "info io_registers"
command) for the following devices: ATmega323, ATmega64, AT90CAN128,
ATmega164p, ATmega324p, ATmega644, ATmega325, ATmega3250, ATmega645,
ATmega6450, ATmega329, ATmega3290, ATmega649, ATmega6490, ATmega640,
ATmega1280, ATmega1281, ATmega2560, ATmega2561, ATmega48, ATmega88,
ATmega168, ATtiny13, ATtiny2313, AT90PWM2, AT90PWM3, AT90PWM2B,
AT90PWM3B, ATmega32M1, ATmega32C1, ATtiny24, ATtiny44, ATtiny84,
ATtiny25, ATtiny45, ATtiny85, ATtiny261, ATtiny461, ATtiny861,
AT90CAN32, AT90CAN64, AT90PWM216, AT90PWM316, AT90USB1287,
AT90USB162, AT90USB646, AT90USB647, ATmega1284P, ATmega165,
ATmega165P, ATmega168P, ATmega16HVA, ATmega3250P, ATmega325P,
ATmega328P, ATmega3290P, ATmega329P, ATmega32HVB, ATmega32U4,
ATmega406, ATmega48P, ATmega644P, ATmega88P, ATtiny167, ATtiny43U,
ATtiny48, ATtiny88, ATmega128RFA1
=====================================================================
Summary of changes in AVaRICE 2.12
==================================
. Many Xmega fixes for firmware versions 7 and above (as shipping by
AVR Studio 5); code breakpoints and accessing the various Xmega
memories appear to almost work now. Many thanks to Detlev Kraft for
his in-depth analysis of the AVR Studio 5 communiction with the ICE.
. Cache the PC returned by BREAK events, to speedup the communication.
. New devices: ATxmega256A3, ATxmega16D4, ATtiny4313
. Moved source code repository from CVS to SVN.
. Implement PDI debugging (JTAGICEmkII / Xmega).
=====================================================================
Summary of changes in AVaRICE 2.11
==================================
. Fixed an annoying error that prevented it from compiling on recent
versions of GCC.
. Fixed *all* warnings, making the code -Wall -Wextra safe, so they
can be enabled by default now. GCC 3.x users might want to run
configure with --disable-warnings though, as some of the warnings
are suppressed by GCC 4.x pragmas.
=====================================================================
Summary of changes in AVaRICE 2.10
==================================
Important bug fixes:
--------------------
. Add a check for the requirement to link against libz in order
to successfully work with libbfd. That appears to be necessary
for GNU binutils >= 2.19.
=====================================================================
Summary of changes in AVaRICE 2.9
=================================
New CPU support added:
----------------------
. ATmega128RFA1
=====================================================================
Summary of changes in AVaRICE 2.8
=================================
New CPU support added:
----------------------
. ATtiny84 and ATtiny85 (debugWIRE devices)
. ATmega32C1, ATmega32M1
. AT90PWM316, AT90USB162, AT90USB646, AT90USB647, ATmega1284P,

ATmega325P, ATmega328P, ATmega3290P, ATmega329P, ATmega32HVB,
ATmega32U4, ATmega406, ATmega48P, ATmega644P, ATmega88P, ATtiny167,
ATtiny43U, ATtiny48, ATtiny88, ATXmega128A1
New features added:
-------------------
. External reset through nSRST (option -R/--reset-srst)
. Handle ICE events (intelligently) beyond just BREAK events
. Option -k/--known-devices to print all known devices
. Default bitrate decreased to 250 kHz to comply with most AVRs
shipping with a CPU frequency of 1 MHz
Summary of important bug fixes:
-------------------------------
. Fix a bug with single-stepping on the JTAG ICE mkII or AVR Dragon.
The bug could eventually result in a "Cannot read program counter"
message.
. Fix a sign-extension bug in the length calculation of received JTAG
ICE mkII packets that could result in a C++ allocation error.
. [ 1869060 ] jtag daisy chain bits limitations
. [ 1833342 ] useless warning message about jtag bitrate using dragon
. [ 1831392 ] --jtag option does not default to usb using dragon
. [ patch 1750202 ] set parameter command failed
. [ 1865183 ] bfd.h not used for checking of libbfd
. [ 1880464 ] AVR-Dragon needs libusb-dev
. [ 1833340 ] cannot read program counter/Watchdog has expired

New features added:
-------------------
. Software breakpoints are now also supported when using JTAG.
Summary of important bug fixes:

robust, and less resource-consuming.
. DebugWire bug fix submittted by Shaun Jackman.
=====================================================================
Summary of changes in AVaRICE 2.6
=================================
New CPU support added:
----------------------
. ATmega164P/324P (removed non-existing ATmega164/324)
New features added:
-------------------
. Support of the AVR Dragon (both, JTAG and debugWire)
Summary of important bug fixes:
-------------------------------
. Don't fork the USB daemon with the libusb handle open;
instead, re-open the connection in the child. Fixes issues
with MacOS X and Cygwin.
=====================================================================
