Installing Fedora on SpacemiT hardware

This page explains how to install and update Fedora on SpacemiT hardware such as the Milk-V K1 and M1 Jupiter and the Banana Pi F3. Only very minimal support for this hardware is upstream at the time of writing, but patches have started to land, so the situation should improve.

Prepare Fedora

Recommended Steps

  • Move / (partition 6) to an NVME disk and resize it. If you do this mount /boot and update root=/dev/mmcblk0p6 to root=/dev/nvme0n1p1 in extlinux/extlinux.conf
  • Resize /boot. (partition 5) The image only has a 256MB /boot partition, which is too small for installing multiple kernels. ~1GB should be fine.
  • Add a /boot/efi partition (partition 6 on mmc if you moved / to nvme). It does not need to be large. 1GB would be beyond adequate. This should be a fat16/fat32/vfat partition with the boot and esp flags set / EFI System partition type.

Boot and Complete

  • Install your storage device(s) and boot
  • Replace /etc/yum.repos.d/fedora-riscv-koji.repo with
[fedora-riscv-koji]
name=Fedora RISC-V Koji
baseurl=http://fedora.riscv.rocks/repos/f41-build/latest/riscv64/
enabled=1
gpgcheck=0

[fedora-riscv-openkoji]
name=Fedora RISC-V Koji
baseurl=http://openkoji.iscas.ac.cn/kojifiles/repos/f41-build/latest/riscv64/
enabled=0
gpgcheck=0
  • dnf remove python3-unbound-1.20.0-2.fc41.riscv64 && dnf -y update # It should not be necessary to uninstall python3-unbound, but dnf has a problem resolving a conflict. It can be reinstalled afterward if needed or wanted.

Optional: Install updated SpacemiT kernel repo and switch to EFI boot

Rust projects have been observed failing to build with 6.1.15 kernel that comes on the image. It also does not have selinux enabled, modules necessary for firewalld to run, etc.

I am attempting to maintain and keep up to date an mainline/stable and LTS 6.6 kernels that more closely resemble a Fedora config with patches from https://github.com/spacemit-com/linux-k1x / https://gitee.com/bianbu-linux/linux-6.6/ until we have proper mainline kernel support. Starting with 6.13.0-rc6 and 6.6.70 it should be possible to efi boot either.

Note: The bpi-f3 will probably get a load access fault error if u-boot is not updated. You can update it by downloading the latest Bianbu 2.0 OS image and dd'ing partitions 1-4 over the existing 1-4 partitions on the sd card.

  • Add /boot/efi to /etc/fstab

/dev/mmcblk0p6 /boot/efi vfat umask=0077,shortname=winnt 0 2

  • Mount it with sudo mount /boot/efi
  • Edit /etc/kernel/cmdline and add suitable commandline arguments:

console=ttyS0,115200 root=/dev/nvme0n1p1 rootfstype=ext4 rootwait rw earlycon clk_ignore_unused quiet loglevel=2

  • Ensure grub2-efi, shim-riscv64-unsigned are installed:

sudo dnf -y install http://fedora.riscv.rocks/kojifiles/packages/shim-unsigned-riscv64/15.8/3.1.riscv64/riscv64/shim-unsigned-riscv64-15.8-3.1.riscv64.riscv64.rpm grub2-common- grub2-tools-minimal grub2-tools grub2-efi-riscv64

  • Edit /boot/env_k1-x.txt and change the bootcmd line to efi boot:

load mmc 0:5 ${fdt_addr_r} dtb/spacemit/${product_name}.dtb; load mmc 0:6 ${kernel_addr_r} EFI/fedora/shimriscv64.efi; bootefi ${kernel_addr_r} ${fdt_addr_r}

=== mainline/stable

  • Add /etc/yum.repos.d/spacemit-mainline.repo
[spacemit-mainline]
name=spacemit-mainline
enabled=1
gpgcheck=0
baseurl=https://people.redhat.com/jmontleo/fedora/linux/releases/41/spacemit-mainline/riscv64/
priority=98

[spacemit-mainline-source]
name=spacemit-mainline-source
enabled=0
gpgcheck=0
baseurl=https://people.redhat.com/jmontleo/fedora/linux/releases/41/spacemit-mainline/source/tree
  • sudo dnf -y update
  • Change SELINUX=enforcing to SELINUX=permissive in /etc/selinux/config
  • touch /.autorelabel
  • reboot, let relabel complete
  • Change SELINUX=permissive back to SELINUX=enforcing in /etc/selinux/config
  • reboot (or just setenforce 1)

=== 6.6 LTS

  • Add /etc/yum.repos.d/spacemit.repo
[spacemit]
name=spacemit
enabled=1
gpgcheck=0
baseurl=https://people.redhat.com/jmontleo/fedora/linux/releases/41/spacemit/riscv64/
priority=98

[spacemit-source]
name=spacemit-source
enabled=0
gpgcheck=0
baseurl=https://people.redhat.com/jmontleo/fedora/linux/releases/41/spacemit/source/tree
  • dnf -y downgrade kernel*
  • dnf -y update
  • dnf -y remove kernel-6.1[01]* kernel-core-6.1[01]* kernel-modules-6.1[01]* kernel-modules-core-6.1[01]*
  • Change SELINUX=enforcing to SELINUX=permissive in /etc/selinux/config
  • touch /.autorelabel
  • reboot, let relabel complete
  • Change SELINUX=permissive back to SELINUX=enforcing in /etc/selinux/config
  • reboot (or just setenforce 1)

=== Old extlinux boot

  • This is not preferred, but you can boot 6.6 kernels using extlinux if for some reason you want to.
  • This script is not required, but will automatically update /boot/extlinux/extlinux.conf when a new kernel is installed. To use it save it as /etc/kernel/install.d/99-update-extlinux.install, ensuring the cmdline root= settings matches your root device.
