Troubleshooting

There's no video output

Check the following,

  • Have you flashed the correct firmware for your board with Bouffalo Dev Cube? There's one .ini file for each board.
  • Make sure USB drive contains /cores/<your_board>/monitor.bin. This is the bitstream that displays the menu.
  • For Primer/Console, use USB-OTG dongle with power pass-through to connect USB and power.
  • For Mega, either use OTG or the USB-A Host port on the board to connect USB drive. If USB-A is used, make sure the switch below is set to "DBG" instead of "FPGA".
  • Do NOT connect the board to PC for power when you intend to run TangCore. Use a separate power supply. The Sipeed firmware enters JTAG/debug mode when PC is detected.
  • For Tang Mega, don't forget to turn on power (long press POWER button on top)

I cannot navigate the menu

Check controller connection. The current version supports dualshock2 controller only.

  • For Mega, insert the DS2 pmod into the left pmod socket (pmod0).
  • For Console, use the top pmod socket (pmod1).
  • For Primer, use the middle pmod socket for DS2.
