Minimig Selftest

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 to test the board when building or when a malfunction is suspected.
