BoF: Mender, Current and Future Status of the Open Source Project
summary
Mender is an open-source OTA system (released a year ago) that combines a small client (~8 MB) and a management server, uses A/B dual-partition rollback so interrupted updates recover, and integrates with Yocto via a meta-layer producing .mender artifacts that include checksums and signatures. Devices poll over HTTP, send detailed failure logs, and run configurable state scripts for timing; current uploads compress images (~50% typical) with delta updates planned (80–90% savings target) and CI/board-integration tooling under development.
