Hardware Information

Milk-V Duo 256M
A USB-A to C or USB-C to C cable
A microSD card
A microSD card reader
A USB to UART debugger (e.g., CH340, CH341, FT2232, etc.)
Optional: Milk-V Duo IOB (Baseboard)

Installation Steps

Method A: Flash community image

Download the prebuilt community image: https://drive.google.com/file/d/1zhhB6AdgvjjuzBWjY6TchdX5b0uNWzP-/view Then flash it with

unzip milkv-duo-256m-alpinelinux-cwt-2023-10-28.img.zip
sudo dd if=milkv-duo-256m-alpinelinux-cwt-2023-10-28.img of=/dev/your/device bs=1M status=progress

Method B: Build and flash your own rootfs

Alternatively, you can also build your own image by replacing relevant content in existing images for the Duo 256M with Alpine’s official rootfs.

Download Alpine minirootfs and Debian image

We will use the kernel and kernel modules from Fishwaldo’s Duo 256M Debian image.

wget https://dl-cdn.alpinelinux.org/alpine/v3.20/releases/riscv64/alpine-minirootfs-3.20.3-riscv64.tar.gz
tar -xvf alpine-minirootfs-3.20.3-riscv64.tar.gz --one-top-level
wget https://github.com/Fishwaldo/sophgo-sg200x-debian/releases/download/v1.4.0/duo256_sd.img.lz4
lz4 -d duo256_sd.img.lz4

Prepare rootfs

Note that the obtained Alpine system is only a “minirootfs” without system packages such as OpenRC. We need to install Alpine’s base packages using apk inside the rootfs in order to make it bootable.

Install Alpine’s package manager `apk`

Skip this step if using Alpine-based distributions on host. Otherwise install apk-tools on your distribution (e.g. on Arch Linux: sudo pacman -S apk-tools).

run apk --help to verify installation.

Install Alpine’s base package `alpine-base` inside minirootfs

(chroot is NOT required)

cd alpine-minirootfs-3.20.3-riscv64
sudo apk add -p . --initdb -U --arch riscv64 --allow-untrusted alpine-base

Extra setups

Edit ./etc/inittab and add the following line (or uncomment) to enable serial access on /dev/ttyS0:
```
ttyS0::respawn:/sbin/getty -L 115200 ttyS0 vt100
```
Edit ./etc/passwd:

Remove the x in root:x:0:0:root:/root:/bin/sh.

(Alternatively, edit /etc/shadow and remove the * in root:*::0:::::).

Flash Debian image (to install the kernel and its modules)

cd ..
sudo dd if=duo256_sd.img of=/dev/your/device bs=4M status=progress

Your device should now be able to detect the root and boot partitions on the SD card.

Mount only the root partition. Inside the partition, backup /lib/modules to somewhere on host:

cd /path/to/your/mnt/root
mv lib/modules /path/to/your/backup

Replace root on SD card with Alpine rootfs

rm -rf /path/to/your/mnt/root/*
cp -r /path/to/your/alpine-minirootfs-3.20.3-riscv64/* /path/to/your/mnt/root/
mv /path/to/your/backup/lib/modules /path/to/your/mnt/root/lib/

Booting and Logging into the System

Insert SD card onto the board and boot. Login into the system via serial port at /dev/ttyUSB0, baudrate 115200.

Default username: root Default password: none

Optional post-installation setups

Setup the password and hostname with passwd and hostname after login.

Setup the system time with date -s, then install cronyd:

apk add cronyd
rc-update add chronyd default

It is recommended to enable the following system OpenRC services (though test results show that the system will still be able to boot nevertheless):

rc-update add hostname boot # required or hostname will not be set properly
rc-update add bootmisc boot
rc-update add networking boot # make sure /etc/network/interfaces is present
rc-update add devfs sysinit
rc-update add mdev sysinit
rc-update add acpid default
rc-update add killprocs shutdown
rc-update add mount-ro shutdown
rc-update add savecache shutdown

Expected Results

The system should boot normally and allow login through the onboard serial port.

Actual Results

The system booted successfully, and login through the onboard serial port was also successful.

Welcome to Alpine!

The Alpine Wiki contains a large amount of how-to guides and general
information about administrating Alpine systems.
