WestfW	a57d315e4b	http://code.google.com/p/arduino/issues/detail?id=368 ... Optiboot does not support ArduinoasISP programmer. When avrdude runs and talks to an arduino running ArduinoISP, it needs the optiboot (entered due to auto-reset) to abort and start the ArduinoISP "application" when it sees communications at the wrong serial speed. Unfortunately, optiboot treats all unrecognized command characters as "no-ops" and responds/loops for more commands, leading to a nice loop that never gets to the sketch. This patch causes characters received with Framing errors (the most likely error for speed mis-matches) to NOT reset the watchdog timer (normally done in getch()), which will cause the application to start if it continues for "a while." (tested. Works! Running ArduinoISP at speeds as high as 57600 still causes the bootloader to start the sketch (although it fails later on for other reasons.))

WestfW	92e746d0a5	This is a relatively significant edit that brings the Arduino copy of ... optiboot up-to-date with the optiboot source repository as of Jun-2011 (the last changes made in the optiboot repository were in Oct-2010) This adds support for several plaforms, fixes the "30k bug", and refactors the source to have separate stk500.h, boot.h, and pin_defs.h These are the arduino opticode issues fixed: http://code.google.com/p/arduino/issues/detail?id=380 optiboot has problems upload sketches bigger than 30 KB http://code.google.com/p/arduino/issues/detail?id=556 update optiboot to the point of the latest optiboot project sources. These are issues that had been solved in the optiboot source aready: http://code.google.com/p/arduino/issues/detail?id=364 optiboot leaves timer1 configured when starting app, breaks PWM on pin 9 and 10. (fixed with a workaround in arduino core.) aka http://code.google.com/p/optiboot/source/detail?r=c778fbe72df6ac13ef730c25283358c3c970f73e Support for ATmega8 and mega88. Fix fuse settings for mega168 _ISP targets Additional new platforms (mega, sanguino) http://code.google.com/p/optiboot/issues/detail?id=26 Set R1 to 0 (already in arduino code) http://code.google.com/p/optiboot/issues/detail?id=36&can=1 Fails to build correctly for mega88 After this commit, the only differences between the Arduino optiboot.c and the optiboot repository optiboot.c are cosmetic.
