Version of Ice40Beeb for Ulx3s ECP5 board
Thanks to David Banks for the Ice40 version
To build and upload the bit file do:
cd ulx3s
make progThe rom is read from flash memory at address 0x80000.
To create the rom do;
cd roms
./build.shThe rom you need is then in roms/boot_c000_f17fff/beeb_roms.bin.
You should then copy that to flash memory, e.g by ftp to the esp32:
put beeb_roms.bin flash@0x80000You can download the BEEB.MMC software archive.
It needs to be unzipped to the root directory of a Fat32 SD card.
Using a PS/2 keyboard connected to us2, do Shift+Print Screen to start the software archive on the SD card.
VGA output is via a Digilent VGA Pmod. HDMI output is not yet supported.
The default build is for the 85f. For other boards use the DEVICE parameter to the make ile, e.g. make DEVICE=12k.
