Using Yocto to Build an IoT OS Targetting a Crossover SoC
summary
Builds a multi-architecture IoT OS for crossover SoCs using Yocto and demonstrates three concrete methods: recipe-level overrides, custom classes, multi-config. Shows a real system with a dedicated M4 security core running Pluton, a TrustZone monitor on an A7, Linux on an A7 and real-time apps on other M4s, all produced from one Yocto-driven pipeline. Uses custom GCC (finds four compiler bugs quickly), integrates firmware artifacts into images, and reports the approach works in production after three years while urging strict isolation and strong debug output.
