Firmware Release Cycle overview

Governed release process for producing, validating, and distributing firmware images to embedded hardware devices. The embedded engineer freezes the release branch, runs the full hardware-in-the-loop regression suite, and generates a signed firmware image with a cryptographic hash. QA validates the image on representative device samples across temperature and voltage corners. Release notes document fixed defects and changed register maps. The image is published to the firmware distribution server and a staged OTA rollout deploys it to the device fleet with automated health monitoring.
