* Updating ATmega168 bootloader to work with standard distributions of avrdude (responding to signature requests made with the universal SPI command) and correctly store EEPROM data. Thanks to ladyada. * Changing compilation process to generate .eep file and allow for use of EEMEM directive (although not yet uploading EEPROM data).

# To build the bootloader for the LilyPad:

# make lilypad

# To burn the bootloader:

# make TARGET=diecimila isp

# make TARGET=ng isp

# 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.
