Farming Together
summary
An engineering run-down of a working board farm ecosystem: builds use Jenkins and kernelCI on top of LAVA, tests run with expect/tcl and containers, and labs report sizes like 80‑board and 120‑board farms. Hardware includes USB relays, custom SD MUX hardware (built but unreliable), HDMI capture, BeagleBone Black power controllers and a PCB shared via KiCad, while Wi‑Fi SD cards prove more reliable than SD MUX and FTDI serial adapters are recommended. The biggest gap is a middle‑layer hardware abstraction so diverse power and USB devices plug into common APIs; a wiki and mailing list are begun.
