Suggestion for how to test the minimig:
Sequence: Jumper 2-3 (MCU TxD) MCU(PIC18) verify it's own operation and sends result too TxD (builtin?) Checks: 20 MHz clock, Flash interface, Rs232(rxd,rts,cts), FPGA jtag Upload test config-1 to FPGA. Check FPGA selftest is ok. Upload test config-2 to FPGA. FPGA Check RAM with patterns. Check CPU with opcode run. Send picture pattern to VGA Check Keyboard with challenge-response. Check Mouse with challenge-response. Send 1 kHz to Left => Silence => 2 kHz Right => Silence => Repeat.. Display joystick1 + joystick2 + keyboard + mouse Testing FPGA: Latch -> ALU+1 -> Latch -> ALU+1 -> Latch -> Repeat..
A test would be useful for building or when a malfunction is suspected.
