Here is some information about board farms.
Contents
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
- See https://lists.yoctoproject.org/g/automated-testing
- (was https://lists.yoctoproject.org/listinfo/automated-testing)
Next meeting
To be determined.
Maybe at Plumbers 2018, Connect, or ELCE 2018
Actions
- define API between test framework and DUT controller layer?
- pduclient?
- labgrid?
- ebfarm?
- ttypersist: provides an application a fake socket for misbehaving ttys
- ttc
- libvirt
- r4d
- survey of existing tools, hardware, practices
- create a definition for an "automated testing" stack - see Automated Testing Stack
- start with definitions from SLAV?
- identify different areas of test automation operation
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
- "Herd Your Boards, Become a Farmer" by Geert Uytterhoeven at ELCE2016
- "Automation beyond Testing and Embedded System Validation" by Jan Luebbe (Pengutronix) at ELCE2017

Best Practices
Issues/Requirements
Misc / Tools
- New horizontally scalable CI system built with Containers and container orchestration technologies in mind - https://github.com/OpenSourceFoundries/jobserv / http://connect.linaro.org/resource/sfo17/sfo17-217/
Hardware
SD muxers
- USB-SD-Mux by Pengutronix, now available
- SD-MUX by Tizen (deprecated - see MuxPi)
- MuxPi by Tizen (MuxPi is the successor to SD-MUX)
- IO-CX by Timesys
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
- usb board with switchable power
- ykush - 3 port USB power switcher - https://www.yepkit.com/products/ykush
- Web Power Switch by Digital Loggers
- control program by Tim Bird: File:Powerswitch-set.sh
- Energenie Power Management System (USB controlled 4-way power switch +2 always on) (UK)
- uhubctl USB hub per-port power control
relays/buttons
- 8-Channel Opto-Isolator Board for Board Farm Control
- DIN Relay IV by Digital Loggers
- This uses the same control protocol as the Web Power Switch mentioned above
- KMTronic 8-channel IP relay controller
- Raspberry Pi relay board
- Relays over ethernet
multi-function
- BayLibre ACME cape - power and temperature measurement with different probes (USB, Jack power cable, HE10)

- Extron USB Switcher
- 2101 USB Connection Exerciser
gpio controllers
HDMI testing
unsorted LAVA hardware helpers
See https://lava.coreboot.org/static/docs/v1/lmp_test_guide.html
Possibly https://github.com/GlasgowEmbedded/glasgow to control various buses (via FPGA).

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
