# Makefile for ATmegaBOOT
# E.Lins, 18.7.2005
# $Id$
#
# Instructions
#
# To build the bootloader for the Diecimila:
# make diecimila
#
# To build the bootloader for the NG/Mini:
# make ng
#
# To build the bootloader for the LilyPad:
# make lilypad
#
# To burn the bootloader:
# make TARGET=diecimila isp
# make TARGET=ng isp
# make TARGET=lilypad isp
# make TARGET=pro8 isp
# program name should not be changed...

# the efuse should really be 0xf8; since, however, only the lower
# three bits of that byte are used on the atmega168, avrdude gets
# confused if you specify 1's for the higher bits, see:
# http://tinker.it/now/2007/02/24/the-tale-of-avrdude-atmega168-and-extended-bits-fuses/
#
# similarly, the lock bits should be 0xff instead of 0x3f (to
# unlock the bootloader section) and 0xcf instead of 0x0f (to
# lock it), but since the high two bits of the lock byte are
# unused, avrdude would get confused.
