Architectures/RISC-V/Installing

Download the latest disk image

Go to this link for the nightly builds and select the most recent (top) build. Look for the -sda.raw.xz file and download it. It will usually be quite large, around 200-300 MB.

unxz Fedora-Developer-Rawhide-xxxx.n.0-sda.raw.xz

The disk image is partitioned, but usually we need a "naked" filesystem. There are several ways to get this, but the easiest is:

guestfish -a Fedora-Developer-Rawhide-xxxx.n.0-sda.raw \
    run : download /dev/sda1 Fedora-Developer-Rawhide-xxxx.n.0-sda1.raw

This creates a naked ext4 filesystem called *-sda1.raw which can be used in qemu or booted on the HiFive Unleashed board.

Boot under qemu

You will need a very recent version of qemu. If in doubt, compile from upstream qemu sources.

Get bbl from here or compile it from source.

    -machine virt \
    -smp 4 \
