Automated remote testing setup

[neuschaefer]

Purpose

I want to test things without carrying server boards around. Some boards fit into my backpack, others simply don't. In any case, setup and teardown takes time and space, which is a bit annoying.

Design

• A control server always runs, and it can be reached via SSH.
• The switchbox is a enclosure with relays that supply power (5V, 12V, 230V, etc.) to different devices
• Switches (relays) are controlled via the switchbox microcontroller, which accepts commands via UART or USB
• A device under test (DUT) has some of the following connections:
  • power supply: via a switch
  • UART for debug control
  • Ethernet
  • perhaps a flash programmer

TODO

• Build/document switchbox
• Write switchbox firmware
• hook up some boards
• evaluate Lava
• write automated test suite
