Required utilities:

  • make
  • lwtools
  • A reasonably modern Nitros9 with the 'ccbkrn' module and Gary's SD drivers installed on /dd (default in modern Nitros9 builds). "cat" or "dd" this rbf image to your SD card.

Optional utilities:

  • toolshead
  • de1flash (for flashing de1 board from linux w/ the quartus gui)

To Install:

  • build the ROM image via "make rom.img".
  • burn the resultant file, rom.img to rom slot 2 of your CoCoFPGA. - this means burning rom.img to flash address 3fc000 in your cocofpga's flash ram.

I use something like this:

quartus_pgm -m jtag -o 'p;de1flash.sof' quartus_stp -t de1flash.tcl write rom.img@0x3fc000

To use:

Set your cocofpga's switch to mpi slot 2 and turn it on. It boots fast, so don't blink.
