Installing OpenWrt on the HiFive Unmatched
Installation on this device is rated moderate. Expect to use a recovery mode, TFTP or a vendor tool rather than a plain web upload. Documented methods: see git-commit.
Flashing third-party firmware can brick a router and usually voids the warranty. Always check that the firmware image matches your exact hardware version.
