From 67f1e949e184491161c91e44bf0393b8b90ab627 Mon Sep 17 00:00:00 2001 From: WestfW Date: Fri, 10 Jun 2011 16:17:13 -0700 Subject: 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.
