Download the RISC-V toolchain https://github.com/xpack-dev-tools/riscv-none-embed-gcc-xpack/releases to the local, then modify ~/.bashrc and import it into environment variables, for example as follows
export PATH=${PATH}:/home/pi/tool/xpack-riscv-none-embed-gcc-10.2.0-1.2/bin
$git clone https://github.com/wuxx/CH32V003-makefile-example
$cd CH32V003-makefile-example
$make
$git clone https://github.com/karlp/openocd-hacks
$cd openocd-hacks
$./bootstrap
$./configure --disable-werror
$make
$make install (can skip this step if other version of openocd is already installed)
use a simple script wlink_write.sh to program, you may need to edit the path of openocd in script
$cd tools
$./wlink_write.sh ../demo/blink_1000.bin
