[Noisebridge-discuss] arduino fuses: how to modify easily?

[Josh Myer]

You can dump them to get absolutely known values; the below is taken from
one of ladyada's Makefiles:

read-fuse:
        $(AVRDUDE) $(AVRDUDE_FLAGS) -u -U lfuse:r:l.txt:r
        $(AVRDUDE) $(AVRDUDE_FLAGS) -u -U hfuse:r:h.txt:r
        $(AVRDUDE) $(AVRDUDE_FLAGS) -u -U efuse:r:e.txt:r

It's also specified in the boards.txt file.  The three that matter:

./arduino/boards.txt:uno.bootloader.low_fuses=0xff
./arduino/boards.txt:uno.bootloader.high_fuses=0xde
./arduino/boards.txt:uno.bootloader.extended_fuses=0x05

./arduino/boards.txt:atmega328.bootloader.low_fuses=0xFF
./arduino/boards.txt:atmega328.bootloader.high_fuses=0xDA
./arduino/boards.txt:atmega328.bootloader.extended_fuses=0x05

./arduino/boards.txt:atmega168.bootloader.high_fuses=0xdd
./arduino/boards.txt:atmega168.bootloader.extended_fuses=0x00
./arduino/boards.txt:atmega8.bootloader.low_fuses=0xdf
