Install OpenOCD:
`sudo apt-get install openocd`
Run the FPGA update with:
`./nprog.sh` if you are using an EPM570 PiStorm board or `./nprog_240.sh` if you are using an EPM240 PiStorm board.
Run the FPGA update with `./flash.sh`, this will automatically detect your CPLD version and flash appropriately.
If successful "Flashing successful!" will appear, if not it will fail with "Flashing failed" and `nprog_log.txt` will be created with more details.
