Atmel ATmega128. Very brief instructions: - Configure your programmer etc. in Makefile.stk501 - Use 'make upload' to flash your STK501. - Setup a SLIP connection to your board (on the first serial port) and make sure you can ping it. - Use 'make loadable_prg.ko' to build a demo module. - gcc -ocodeprop ../../tools/codeprop.c - ./codeprop <IP of STK> loadable_prg.ko - Watch the module print "Tick, Tack, Tick, ..." on the second serial port.
