Setting up a Tiny Tapeout FPGA demo board¶

  • Tiny Tapeout FPGA demo board wiring to a Raspberry Pi: which board signal goes to which Raspberry Pi pin or port.

  • How to install the Tiny Tapeout FPGA packages: the fpgas.online packages for the board, and the check.

  • How to stop the fpgas-tt daemon and start it again: hold the serial port for a tool of your own, then give it back.
