Arch Linux Milk-V Duo S Test Report

Test Environment

Operating System Information

  • System Version: archriscv-2025-06-12

You need to build this image on your own.

Note: This image is provided by community developers and is not an official image.

Hardware Information

  • Milk-V Duo S
  • A USB Power Adapter
  • A USB-A to C or USB C to C Cable
  • A microSD Card
  • A USB to UART Debugger (e.g., CH340, CH341, FT2232, etc.)
  • Three Dupont Wires

Build Steps

Build Buildroot

See milkv-duo/duo-buildroot-sdk.

After the first build of target milkv-duos-sd is completed, modify build/boards/cv181x/cv1813h_milkv_duos_sd/linux/cvitek_cv1813h_milkv_duos_sd_defconfig and add the following lines.

CONFIG_CGROUPS=y
CONFIG_CGROUP_FREEZER=y
CONFIG_CGROUP_PIDS=y
CONFIG_CGROUP_DEVICE=y
CONFIG_CPUSETS=y
CONFIG_PROC_PID_CPUSET=y
CONFIG_CGROUP_CPUACCT=y
CONFIG_PAGE_COUNTER=y
CONFIG_MEMCG=y
CONFIG_CGROUP_SCHED=y
CONFIG_NAMESPACES=y
CONFIG_OVERLAY_FS=y
CONFIG_AUTOFS4_FS=y
CONFIG_SIGNALFD=y
CONFIG_TIMERFD=y
CONFIG_EPOLL=y
CONFIG_IPV6=y
CONFIG_FANOTIFY=y

Then start build again and get image out/milkv-duos-sd-<your-build-timex>.img.

Update rootfs

Consider use root to avoid permission issues.

Download rootfs

Get rootfs from Arch Linux RISC-V.

wget https://archriscv.felixc.at/images/archriscv-2025-06-12.tar.zst

Modify rootfs

sudo losetup -f

Output is /dev/loop0.

Mount the image on the loop device.

losetup -P loop0 out/milkv-duos-sd_2025-0831-0547.img

Mount disk to /mnt/duo-rootfs.

mkdir /mnt/duo-rootfs
cd /mnt/duo-rootfs
mount /dev/loop0p3 /mnt/duo-rootfs

Remove everything.

rm -rf ./*

Unzip new rootfs.

tar -xvf archriscv-2025-06-12.tar.zst -C .

Download Package for Network.

To use the network, download some packages to the directory for installation.

cd /mnt/duo-rootfs/root
wget https://mirror.iscas.ac.cn/archriscv/repo/core/nano-8.2-1-riscv64.pkg.tar.zst
wget https://mirror.iscas.ac.cn/archriscv/repo/extra/dhcpcd-10.0.10-1-riscv64.pkg.tar.zst

Unmount Image

umount /dev/loop0p3
losetup -d /dev/loop0

Installation Steps

Using dd to Flash the Image to the microSD Card

dd if=milkv-duos-sd_2025-0831-0547.img of=/dev/sdc bs=1M status=progress

Logging into the System

Logging into the system via the serial port.

Username: root Password: archriscv

Configure the network

Install these downloaded package.

pacman -U ./dhcpcd-10.0.10-1-riscv64.pkg.tar.zst
pacman -U ./nano-8.2-1-riscv64.pkg.tar.zst

Then start dhcp service.

ip link set end0 up
systemctl start dhcpcd.service
systemctl enable dhcpcd.service

If static network needs configuring, use following commands.

ip link set end0 up
ip addr add 172.16.0.188/12 broadcast 172.31.255.255 dev end0 #172.16.0.188/12 is your local IP，172.31.255.255 is broadcast IP.
ip route add default via 172.16.0.1 # default gateway
echo -e "nameserver 172.16.0.1" >> /etc/resolv.conf # DNS server

A reboot might be needed.

Expected Results

The system boots up normally and allows login through the serial port.

Actual Results

The system boots up normally and login through the serial port is successful.
