For the icebreaker, the hardware connections are :

To run :

Build and flash the bitstream
- This will build fw/boot.hex and include it as the BRAM initial data
Flash the main application code in SPI at offset 1M
- make -C fw prog
Connect to the iCEBreaker uart console (ttyUSB1) with a 1M baudrate
- and then at the Command> prompt, press c for 'connect'. This will start the USB detection and device should enumerate
