Installation Steps

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

Preparing the System Environment

Install the required packages:

sudo apt install -y scons libncurses5-dev device-tree-compiler
# or on Arch Linux: sudo pacman -S scons dtc ncurses 

Get the toolchain:

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

Fetching the Source Code and Compiling the Firmware

git clone --depth=1 https://github.com/RT-Thread/rt-thread
cd rt-thread/bsp/bouffalo_lab/bl70x
scons --menuconfig
source ~/.env/env.sh
pkgs --update
scons -j$(nproc) --verbose

The generated firmware file is at ./rtthread.bin

Flash firmware

Short the BOOT pin and the 3V pin on the board with a Dupont cable, then power it on to enter flashing mode.

Flash the firmware to board (the board has built-in serial device):

cd ../
sudo ./bouffalo_flash_cube.sh bl702 /dev/ttyACM0

(The script will automatically detect and download bouffalo_flash_cube to the compilation directory.)

Logging into the System

Logging into the system via the serial port.

Expected Results

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