Build Heterogenous System Using Yocto Project
summary
Yocto Project builds a single heterogeneous image by converting a vendor XSA into a System DeviceTree, running the lopper tool to prune and produce per-CPU DTS and driver lists, then auto-generating multiconfig machine files, YAML driver manifests, Xparameters headers and package metadata. The workflow produces Linux, FreeRTOS, baremetal and microblaze artifacts, supports PL overlays and OpenAMP firmware packaging, and now prefers the Python gen-machine-con flow (replacing DT processor) to emit ready-to-build Yocto multiconfigs and SDKs.
