RT-Thread Milk-V Duo 256M Test Report

Test Environment

Operating System Information

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.)

Installation Steps

The following steps are tested on Arch Linux, but should be applicable to all major Linux distributions.

Fetch Source Code and Compile Firmware

Obtain the toolchain and configure it:

wget https://github.com/RT-Thread/toolchains-ci/releases/download/v1.7/riscv64-linux-musleabi_for_x86_64-pc-linux-gnu_latest.tar.bz2

tar -xjvf riscv64-linux-musleabi_for_x86_64-pc-linux-gnu_latest.tar.bz2

Update the following paths as needed:

export RTT_CC_PREFIX=riscv64-unknown-linux-musl-
export RTT_EXEC_PATH=/opt/riscv64-linux-musleabi_for_x86_64-pc-linux-gnu/bin

Fetch dependencies:

sudo apt install -y scons libncurses5-dev device-tree-compiler
# or on Arch Linux: sudo pacman -S scons dtc ncurses 
git clone --depth=1 https://github.com/RT-Thread/rt-thread
cd rt-thread/bsp/cvitek/cv18xx_risc-v
# Generate configuration
scons --menuconfig

In menuconfig, please select milkv-duo256m under the Board Type option. Enter RT-Thread Kernel submenu ---> Select Enable RT-Thread Smart (microkernel on kernel/userland) to enable the RT-Smart kernel.

source ~/.env/env.sh
pkgs --update
scons -j$(nproc) --verbose
cd ../
./combine-fip.sh $(pwd)/cv18xx_risc-v Image

boot.sd and fip.bin files will be generated in the cvitek/output/milkv-duo256m directory upon completion.

Fetch Source Code and Compile RT-Smart userapps

Fetch dependencies:

sudo apt install -y unzip xmake

Compile:

git clone https://github.com/RT-Thread/userapps.git
cd userapps
source env.sh
cd apps
xmake f -a riscv64gc
xmake -j$(nproc)

Build Image:

xmake smart-rootfs
xmake smart-image -f ext4

The userapp image would be generated at userapps/apps/build/ext4.img.

Prepare microSD Card

Clear the microSD card and create a FAT32 partition:

wipefs -af /path/to/your-card
mkfs.fat /path/to/your-card

Copy the generated boot.sd and fip.bin files onto the microSD card. The storage card is now ready to boot RT-Thread on the Duo 256M.

Logging into the System

Log into the system via the serial port.

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.
