  • Setup bootloader to initialize pins to a known safe state
  • Pulled pindefs for the toolbox out of the toolbox into common/toolbox_pindefs.h
  • Shared toolbox pindefs with the bootloader
  • Replaced all raw pin names with the #defined names
  • Optimizied out some bytes out of the bootloader by sharing variables

Bootloader only emits a boot message when the buttons are depressed or it was reset by a watchdog
199 02/24/2010 10:16 PM Kevin Woo

Bootloader is setup to read the address from the EEPROM now
198 02/24/2010 06:24 PM Kevin Woo

Fixed a magic number initialization
197 02/24/2010 06:21 PM Kevin Woo

Removed fuse writing since it seems to be placing the fuses out of memory and causing the programmer to fail
196 02/24/2010 05:57 PM Kevin Woo
  • Fixed bug where the naked attribute did not work with main
  • Used a noreturn attribute to main_start which saved us some room. That works
  • Tested removal of interrupt tables, this works
195 02/24/2010 03:54 PM Kevin Woo

Using a modified linker script to strip out the unused interrupt vector table in the bootloader. Not tested
194 02/24/2010 02:47 PM Kevin Woo

Added default fuses to the bootloader
193 02/24/2010 02:34 AM Kevin Woo

Made the main function in the bootloader naked, saved about 50 bytes
190 02/24/2010 01:37 AM Kevin Woo

Added the assembly jump table. It is placed 1 page from the end of flash memory
