Build Heterogenous System Using Yocto Project
summary
Pipeline converts an SoC XSA into a single Yocto multiconfig build by running the system DeviceTree through lopper (or the Python gen-machine-conf tool) to emit machine .conf, per-core DTS, driver lists and bare‑metal headers; the generated multiconfig files then build and package Linux, FreeRTOS/Zephyr, baremetal, Xen/OpenAMP firmware and PL overlays. Workflow requires AMD hardware tools and embedded‑software repos, produces identical artifacts for QEMU or silicon, and is already used in the scarp GAP/gen‑machine workflow.
