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

Presentations

If you know of a presentation on this topic, please add it below:

  • "Test Standards - Can Fuego, Lava and others agree?" by Tim Bird at Linaro Connect SFO 2017
    • description: Tim proposes several areas of standardization collaboration between different Linux test initiatives
    • Slides and Video
  • "Herd Your Boards, Become a Farmer" by Geert Uytterhoeven at ELCE2016
  • "Automation beyond Testing and Embedded System Validation" by Jan Luebbe (Pengutronix) at ELCE2017
  • Introduction to kernelCI.org
  • Piece of cake - testing remote embedded devices made easy with MuxPi by Paweł Wieczorek at FOSDEM 2018

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
  • LAVA-LMP suite of boards:
    • LAVA-LMP LSGPIO - tests GPIO audio hot-plug, SPI bug - can do boot source selection, switch actuation simulation LED state confirmation, scanned keypress simulation
    • LAVA-LMP ETH+SATA - for testing 10/100 Ethernet and SATA connect and disconnect testing
    • LAVA-LMP HDMI - for testing HDMI hot-plug test, EDID: monitor emulation and activity recording, and more
    • LAVA-LMP SD MUX - for SD-related testing (bootloader, SD card hot-plug testing)

USB mega-ports

A few people are using these:

USB switchers

gpio controllers

unsorted LAVA hardware helpers

See https://lava.coreboot.org/static/docs/v1/lmp_test_guide.html

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
