Build Zephyr for MicroBlaze-V FPGA Using Yocto Project
summary
Yocto uses multiconfig plus meta-zephyr and vendor layers to produce a packaged Zephyr kernel, drivers and apps for MicroBlaze‑V RISC‑V FPGA; workflow converts Vivado XSA → System DeviceTree (SDT) via SDT‑gen, prunes and emits Zephyr DTS/Kconfig using looper, then generates machine and multiconfig files for BitBake. Requires Vivado, meta‑virtualization/meta‑arm/meta‑xylinx, and a patched meta‑zephyr (backported Zephyr 3.7 LTS); automated gen‑machine‑conf is coming this fall, current limitations include incomplete QEMU/bitstream deploy and missing upstream LTS support.
