To send the generated bitstream to the usb-connected FPGA use: dfu-util -D beagle-spi.dfu.

Master initializes the comm. First byte is a command:

COMMANDS:

• NOOP: Receive back the number of free slots we have in fifo.
• STATUS: return as next 4 bytes the status
• FILL_FIFO: The next transaction put all the data in fifo (until channel select is up again)

To run symbiosis, use sby -f fifo.sby
