# 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

# 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.
