We developed a small breakout board to simplify bench test of the new mezzanine board. This board provides a convenient way to power the board, program the microcontroller and access the configuration interface.

The board requires 5V power. Connect the AVdd_in and DVdd_in together to +5V and AGND and DGND (jumpered already) to the supply GND terminal.

Use a Sparkfun FTDI serial breakout (like ​this one or ​this other one) to connect to a computer. Use a terminal emulator (minicom works well in Linux) set to 9600 baud, 8 bits, no parity, no handshaking.

Connect the mezz card to the board using a ribbon cable.

Power up the board, and you should see the microcontroller announce itself:

  MezzNg V1.0

See MezzNgMicrocontroller for details on the protocol.
