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://occ-oss-prod.oss-cn-hangzhou.aliyuncs.com/resource//1705395512373/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1-20240115.tar.gz

tar -xzvf Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1-20240115.tar.gz

Update the following paths as needed:

export RTT_CC_PREFIX=riscv64-unknown-elf-
export RTT_EXEC_PATH=/opt/Xuantie-900-gcc-elf-newlib-x86_64-V2.8.1/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
source ~/.env/env.sh
pkgs --update
scons -j$(nproc) --verbose
cd ../
./combine-fip.sh $(pwd)/cv18xx_risc-v Image

Please select milkv-duo256m under the Board Type option in menuconfig.

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

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.
