Yocto on Risc V
summary
How to build a Yocto Linux distribution for RISC‑V using Yocto/BitBake and devtool to fetch, patch, and package sources, produce a rootfs and run it under QEMU emulation. The workflow covers targeting the HiFive Unmatched (Freedom U740), adding a custom hello application as a recipe and running the patched binary in QEMU, noting that initial builds are slow while rebuilds use a cache and are much faster, and describing an attempted flash to the real board with some issues.
