From Code to Board: Grinn Hardware Automation Whitepaper

This whitepaper walks you through how to bring real hardware into a CI pipeline using LAVA (Linaro Automated Validation Architecture), breaking down the full architecture behind it - the LAVA server acting as control plane, the dispatcher doing the physical work in the lab, and a dedicated runner bridging GitLab jobs to real boards.


Along the way, you'll see how device templates abstract away the messy, board-specific details of flashing and booting, how a dispatcher can operate a remote lab from another city without the central server ever needing to know the difference, and what actually happens between a job being submitted and a board reporting pass or fail.


It's worth a read if you want to see what hardware testing looks like once it's automated end to end.
