Read low fuse bits into file low:
sudo avrdude -p m2560 -c usbtiny -U lfuse:r:low:r
Write low fuse bits from file low. It should contain single FF byte:
sudo avrdude -p m2560 -c usbtiny -U lfuse:w:low:r
Write high fuse bits from file high. It should contain single D8 byte:
sudo avrdude -p m2560 -c usbtiny -U hfuse:w:high:r
Write the firmware image:
sudo avrdude -p m2560 -c usbtiny -U flash:w:calc.ino.hex:i
