Board Farm

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.

Add your name and contact information if you would like to be notified when an e-mail list is created, or are generally interested in this topic:
 * Andrew Murray - 
 * Tim Bird - 
 * Robert Schwebel 
 * Arnout Vandecappelle - -- doesn't have a board farm but is interested
 * Mirza Krak - 
 * Alan Bennett - 
 * Geert Uytterhoeven - 
 * Andrea Scian - 
 * Kieran Bingham - 
 * Jan Lübbe - 
 * Marco Cavallini - 
 * Kevin Hilman - 
 * Bill Mills - 
 * Tom Gall - 
 * Stephano Cetola - 
 * Mike Holmes - 
 * Matteo Vit - 

At present the expectation is to hijack this mailing list - https://lists.yoctoproject.org/listinfo/automated-testing

= Actions =
 * create a mailing list?
 * define API between test framework and DUT controller layer?
 * pduclient?
 * labgrid?
 * ebfarm?
 * ttypersist: provides an application a fake socket for misbehaving ttys
 * ttc|
 * survey of existing tools, hardware, practices
 * collection of presentations?
 * that is, add a list of presentations on this topic from previous conferences
 * "Herd Your Boards, Become a Farmer" by Geert Uytterhoeven at ELCE2016
 * [[Media:Herd_Your_Boards.pdf | Slides]] and Video
 * "Automation beyond Testing and Embedded System Validation" by Jan Luebbe (Pengutronix) at ELCE2017
 * [[Media:PRE-trunk-ELCE-Automation-beyond-Testing.pdf | Slides ]] and Video
 * Introduction to kernelCI.org
 * Blog Article and Video

= 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.
