Here is some information about board farms.

Community

At the Embedded Linux Conference Europe 2017 Andrew Murray held a BoF session titled Farming Together. The purpose of this BoF was to bring together people that are actively working on board farms to create a community, to knowledge share and to start a collaborative effort.

Mailing list

Discussions on this topic have started at on the "Automated Testing" mailing list of the Yocto Project

Next meeting

To be determined.

Maybe at Plumbers 2018, Connect, or ELCE 2018

See Automated Testing Summit

Best Practices

Issues/Requirements

Misc / Tools

Hardware

SD muxers

  • USB-SD-Mux by Pengutronix
  • SD-MUX by Tizen (deprecated - see MuxPi)
  • MuxPi by Tizen (MuxPi is the successor to SD-MUX)

Kevin Hilman mentioned (at ELCE 2017) wifi SDCards as a way to handle the SD mux problem. Was he referring to something like these? http://techpp.com/2015/04/28/wifi-sd-cards-camera/

power control

relays/buttons

multi-function

  • BayLibre ACME cape - power and temperature measurement with different probes (USB, Jack power cable, HE10)
  • Sony_Debug_Assist_board - Open Hardware design by Sony for multi-function DUT controller (USB, serial, power, buttons)
    • connection to host = USB
  • MuxPi by Tizen Open Hardware design by Samsung for multi-function DUT controller (serial, power, buttons, network?)
    • connection to host = network

USB mega-ports

A few people are using these:

Software

Notes

  • spend money on USB serial adapter cables - cheap adapters sometimes drop connections and are a pain to debug
    • FTDI cables seem to work well.

Farm Survey

Tim Bird is conducting a survey of Farm hardware (DUT controllers). See this page: Board Farm Survey
