MMCTester

MMCTester provides a way to test a MMC using an Arduino UNO compatible board.

Quickstart

• Program the sketch in mmctester-board to an Arduino UNO compatible board

• Connect IPMB to pins D14 (SDA) and D15 (SCL)

• Connect GND if the power circuit is not shared

• [Optional] Use digital pin D13 (for example) to indicate when the payload power is activated

• [Optional] Use digital pin D3 (for example) to control the hotswap switch

• Install mmctester package making sure you have the latest python-ipmi

• Run: mmctester --port /dev/ttyACM0 --pin-pg 13 --pin-hs 3 (replace serial port path and pins accordingly)

This will show a tui interface with FRU and SDR info, when a HotSwap event is detected, the power-good pin (pin-pg) will be set acordingly to emulate that power has been given. Additionally, the number keys can be used to manually control some of the digital outputs, pin-hs can be used to programatically control the HotSwap switch if the board has been wired accordingly.

Demo:

$ mmctester --port /dev/ttyACM0
