Bootloader

Building the bootloader requires an avr-gcc toolchain, in the bootloader/ directory, to build run:

make

Flashing the firmware on the device requires avrdude and a compatible hardware programmer. Default configuration is stored at the beginning of the Makefile. To program with the default configuration, run:

make load

Fuses can be programmed running:

make fuse

Firmware

Building the firmwware requires an avr-gcc toolchain, in the firmware/ directory, to build run:

make

Flashing the firmware on the device requires avrdude and a compatible hardware programmer. Default configuration is stored at the beginning of the Makefile. To program with the default configuration, run:

make load

or using the bootloader (this will reset the device if possible):

make boot

Hardware

All hardware files (schematic, layout and libraries) are in CadSoft Eagle format.
