AVR gdb Notes

  1. Check the version number on avr-gdb as of December 2021, it is 11.1. On Ubuntu, the latest version is 8.1 from 2018 which had quite a few bugs. Attempted to build it manually (which failed), so I spun up a Manjaro (Arch Linux) instance to get the latest. Crazy, I know.
  2. Start avarice in a separate window using, then launch gdb in another window:
    avarice -g -w -d -P atmega328p :3333 	# window 1
    avr-gdb -tui							# window 2
  3. If avarice crashes on startup, cycle power on both the debugger (Dragon) and the target (Uno)
