openEuler Milk-V Duo 256M Test Report

Test Environment

Operating System Information

• System Version: openEuler-23.09-V1

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 256M
• 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_duo256m_sd is completed, modify build/boards/cv181x/cv1812cp_milkv_duo256m_sd/linux/cvitek_cv1812cp_milkv_duo256m_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-duo256m-sd-20240924-2106.img.

Update rootfs

Consider use root to avoid permission issues.

Download rootfs

Get rootfs from ISCAS Mirror.

wget https://mirror.iscas.ac.cn/openeuler-sig-riscv/openEuler-RISC-V/preview/openEuler-23.09-V1-riscv64/openeuler-rootfs.tar.gz

Modify rootfs

sudo losetup -f

Output is /dev/loop0.

Add extra space to your image.

qemu-img resize out/milkv-duo256m-sd-20240924-2106.img +10G

Mount the image on the loop device.

losetup -P loop0 out/milkv-duo256m-sd-20240924-2106.img

Expand your image.

sudo fdisk /dev/loop0

# 以下在 fdisk 中
d
2
n
p
2
# keep default for start sector.
# keep default for end sector.
w

# 以下应回到bash
sudo mkfs.ext4 /dev/loop0p2

Mount disk to /mnt/duo-rootfs.

mkdir /mnt/duo-rootfs
cd /mnt/duo-rootfs
mount /dev/loop0p2 /mnt/duo-rootfs

Remove everything.

rm -rf ./*

Unzip new rootfs.

tar -xvf openeuler-rootfs.tar.gz -C .

Unmount Image

umount /dev/loop0p2
losetup -d /dev/loop0

Installation Steps

Using dd to Flash the Image to the microSD Card

dd if=milkv-duo256m-sd-20240924-2106.img of=/dev/sdc bs=1M status=progress

Logging into the System

Logging into the system via the serial port.

Username: root Password: openEuler12#$

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.
