This Atmel firmware manages the upload of an Atari OS Image (e.g. EmuTOS or Atari OS) through the Suska FPGA into the Flash PROMS of Suska. Before this works, it is necessary to have the FPGA configware programmed into the FPGA boot device. On the PC side there is a Linux program (suska-flasher) that sends the OS Image to the Atmel. The program connects the PC via a serial USB interface to the Atmel.
