2011-10-10Shrink code by using registers for variables "length" and "address"WestfW
http://code.google.com/p/optiboot/issues/detail?id=33 Fix high-value watchdog timeouts on ATmega8 http://code.google.com/p/optiboot/issues/detail?id=38 Change "start app on bad commands" code to start the app via the watchdog timer, so that the app is always started with the chip in fully reset state. http://code.google.com/p/optiboot/issues/detail?id=37 (cherry picked from commit 6f7687b0f925cb07447cbbcc692766c51c02f700)
2011-10-10Add a version number to the optiboot source and binary.WestfW
http://code.google.com/p/arduino/issues/detail?id=554 end of flash memory where they can be read (at least in theory) by device programmers, hex-file examination, or application programs. This is done by putting the version number in a separate section (".version"), and using linker/objcopy magic to locate that section as appropriate for the target chip. (See http://lists.gnu.org/archive/html/avr-gcc-list/2011-02/msg00016.html for some discussion on the details.) Start the version at 4.1 (the last "packaged" version of optiboot was called version 3, so the "top of source" would be 4.0, and adding the version number makes 4.1) Refactor LDSECTION in the Makefile to LDSECTIONS so that multiple section start addresses can be defined. Change the _isp makefile definitions to make the bootloader section readable (but not writable) by the application section. (This would need to be done elsewhere as well to handle all bootloader programming techniques. Notably Arduino's boards.txt Note that this change does not change the "code" portion of optiboot at all. The only diffs in the .hex files are the added version word at the end of flash memory.

2011-10-10This is a relatively significant edit that brings the Arduino copy ofWestfW
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. (cherry picked from commit e2812ef91cc1489527827dcd14c843f3b3244f36)
2011-10-10http://code.google.com/p/arduino/issues/detail?id=517WestfW
Remove the trailing comments when setting fuse values for the various *_isp targets, so that they won't cause avrdude errors. This was done the same way as in the optiboot source tree: http://code.google.com/p/optiboot/issues/detail?id=17 http://code.google.com/p/optiboot/source/detail?r=005fb033fc08c551b2f86f7c90c5db21549b3f20 (cherry picked from commit 6840b77643a75b850d48bed80c578da484e6559f)
2011-10-10Makefile modification to allow building optiboot in more environments.WestfW
Allows building within the Arduino Source tree, and within the Arduino IDE tree, as well as using CrossPack on Mac. Adds README.TXT to track arduino-specific changes (and documents the new build options.) This addresses Arduino issue: http://code.google.com/p/arduino/issues/detail?id=487 And optiboot issue http://code.google.com/p/optiboot/issues/detail?id=1 (which can be thought of as a subset of the Arduno issue.) Note that the binaries produced after these Makefile changes (using any of the compile environments) are identical to those produced by the crosspack-20100115 environment on a Mac. (cherry picked from commit 2d2ed324b48e709f59a002cb274ed60bb0ebc911)

* Updating ATmega168 bootloader to work with standard distributions of avrdude (responding to signature requests made with the universal SPI command) and correctly store EEPROM data. Thanks to ladyada. * Changing compilation process to generate .eep file and allow for use of EEMEM directive (although not yet uploading EEPROM data).
