The GoodFET41 is the thirteenth hardware revision of the GoodFET, owing its heritage to the GoodFET40. It retains most of that model's design while being manufactured on a thicker board for stability and adding a Spy-Bi-Wire connector for compatibility with eZ430 target boards.

Build and flash firmware with the following commands. This board self-flashes over USB through a masked-ROM bootloader, so there is no need for an external programmer.

export board=goodfet41
make clean install
