Architectures/RISC-V/Build Bootable Image

Build Fedora Image for RISC-V development board

Setup Environment

We use latest Fedora Qemu image for RISC-V64 from riscv.rocks or a mirror in China to boot a RISC-V Qemu for building a Fedora Remix image.

Making Image by Appliance-tools

Appliance-tools is used to build Fedora images, which has already installed in the image.

Download Pre-build image and Uncompress

$ wget http://fedora.riscv.rocks/kojifiles/work/tasks/8517/1128517/Fedora-Developer-Rawhide-20210421.n.0-sda.raw.xz
$ xz -d Fedora-Developer-Rawhide-20210421.n.0-sda.raw.xz

Download Firmware

$ wget http://openkoji.iscas.ac.cn/pub/dl/fw_payload-uboot-qemu-virt-smode.bin

Resize Image

The original image size is not enough for image building, we need enlarge it first.

$ qemu-img resize Fedora-Developer-Rawhide-20210421.n.0-sda.raw +40G

Boot RISC-V Qemu

qemu-system-riscv64    -nographic \
                       -machine virt \
                       -smp 4 \
                       -m 2G \
                       -kernel fw_payload-uboot-qemu-virt-smode.bin \
                       -bios none \
                       -object rng-random,filename=/dev/urandom,id=rng0 \
                       -device virtio-rng-device,rng=rng0 \
                       -device virtio-blk-device,drive=hd0 \
                       -drive file=Fedora-Developer-Rawhide-20210421.n.0-sda.raw,format=raw,id=hd0 \
                       -device virtio-net-device,netdev=usernet \
                       -netdev user,id=usernet,hostfwd=tcp::10000-:22

Resize rootfs on Qemu

# growpart /dev/vda 2
# resize2fs /dev/vda2
# reboot

Prepare kick start file

The original Kickstart files is from riscv.rocks: fedora-riscv-kickstarts.

The kick start file for a specific board can be modified from these files.

For Allwinner D1, the example kickstart file REPO is here .

For StarFive Starlight Board, the example kickstart file REPO is here .

Run appliance tool to build new image on QEMU

appliance-creator -c kickstartfile.ks \
                  --cache ${CACHE_DIR} \
                  --format raw \
                  --name ${IMAGE_NAME} \
