DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owners would know how get the best out of that hardware.

The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware.

If you need help to get Debian running on your hardware, please have a look at our user support channels where you may find specific channels (mailing list, IRC channel) dedicated to certain types of hardware.

Important Note

Debian on the ?HiFive Unmatched is very new. There are no official images available yet.

You could find some experimental images in (signed with ?Deiv's key):

This images are built with the same instructions in the next section. You just need to decompress them and burn to sd-card.

Installing Debian on HiFive

The easiest way at present to run Debian binaries on a ?HiFive is to generate an sdcard image with all the Debian stock parts.

Preparing disk image

# create image file
dd if=/dev/zero of=debian-sid-risc-v-sifive-unmatched.img bs=1M count=4096

# Partition image with correct disk IDs
sudo sgdisk -g --clear --set-alignment=1 \
       --new=1:34:+1M:    --change-name=1:'u-boot-spl'    --typecode=1:5b193300-fc78-40cd-8002-e86c45580b47 \
       --new=2:2082:+4M:  --change-name=2:'opensbi-uboot' --typecode=2:2e54b353-1271-4842-806f-e436d6af6985 \
       --new=3:16384:+130M:   --change-name=3:'boot'      --typecode=3:0x0700  --attributes=3:set:2  \
       --new=4:286720:-0   --change-name=4:'rootfs'       --typecode=4:0x8300 \

# Mount image in loop device
sudo losetup --partscan --find --show debian-sid-risc-v-sifive-unmatched.img

# format partitions
sudo mkfs.vfat /dev/loop0p3
sudo mkfs.ext4 /dev/loop0p4
sudo e2label /dev/loop0p3 boot
sudo e2label /dev/loop0p4 rootfs

Installing debian sid+riscv-port on image

# mount root partition
sudo mount /dev/loop0p4 /mnt

# install base files
sudo apt-get install debootstrap qemu-user-static binfmt-support debian-ports-archive-keyring
sudo debootstrap --arch=riscv64 --keyring /usr/share/keyrings/debian-ports-archive-keyring.gpg --include=debian-ports-archive-keyring unstable /mnt http://deb.debian.org/debian-ports

# mount boot partition
sudo mount /dev/loop0p3 /mnt/boot

# chroot into base filesystem and made basic configuration
sudo chroot /mnt

Inside created chroot:

# Update package information
apt-get update

# Set up basic networking
cat >>/etc/network/interfaces <<EOF
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
EOF

# Set root password 'sifive'

# Change hostname

# Set up fstab
cat > /etc/fstab <<EOF

# Install kernel and bootloader infrastructure
apt-get install linux-image-riscv64 u-boot-menu u-boot-sifive
apt-get clean

# add needed modules in initrd
echo mmc_spi >>/etc/initramfs-tools/modules 
#update-initramfs -u (TODO: add more space in boot)
rm /boot/initrd*
update-initramfs -c -k all

# Set up u-boot (TODO: better integration for kernel updates)
cp /usr/lib/linux-image-5.14.0-3-riscv64/sifive/hifive-unmatched-a00.dtb /boot/
echo U_BOOT_FDT=\"hifive-unmatched-a00.dtb\" >> /etc/default/u-boot

# Install ssh server and ntp
apt-get install openssh-server openntpd ntpdate
apt-get clean

# set the time immediately at startup
sed -i 's/^DAEMON_OPTS="/DAEMON_OPTS="-s /' /etc/default/openntpd

# exit chroot
exit

Once out of chroot:

sudo rm /mnt/root/.bash_history

Setup bootloaders

sudo dd if=/mnt/usr/lib/u-boot/sifive_unmatched/u-boot-spl.bin of=/dev/loop0p1 bs=4k iflag=fullblock oflag=direct conv=fsync status=progress
sudo dd if=/mnt/usr/lib/u-boot/sifive_unmatched/u-boot.itb of=/dev/loop0p2 bs=4k iflag=fullblock oflag=direct conv=fsync status=progress

Finish and write image to sdcard

sudo umount /mnt/boot
sudo umount /mnt

sudo losetup -d /dev/loop0

# take care of writing to the correct sdcard-device
sudo dd if=debian-sid-risc-v-sifive-unmatched.img of=/dev/sdcard-device bs=64k iflag=fullblock oflag=direct conv=fsync status=progress
