Upstream LTS Component for Product Delivery
summary
Company migrates embedded products from vendor BSPs to upstream Linux, U-Boot and Buildroot over a seven-year migration, consolidating ~60 product variants across three OS lines and ~50,000 devices. Outcome: standard LTS kernels (6.6 → targeting 6.12), unified update format, and automation via Jenkins + labgrid automation that cuts manual maintenance to ~100 hours/month. Engineers upstream hundreds of fixes—touch controller, clock/NAND, U-Boot—and run upstreamed 100+ patches and continuous CV scanning, proving the approach reduces update cost and improves security.
