wch32_macos

Compile & Flash RISC-V WCH32 MCUs on Apple Silicon.

Examples

• CH32V003
• CH32V307

Preparing Toolchains

• Download MRS toolchain from MacOS tab at http://www.mounriver.com/download

• Download Compiler from https://github.com/xpack-dev-tools/riscv-none-embed-gcc-xpack/releases/

• Download Wlink for arm64 from https://github.com/ch32-rs/wlink/releases/tag/nightly

• Install required tools with homebrew by

  brew install libusb
  

• Extract MRS toolchain and Wlink into same directory.

First example on CH32V003 board

• Clone this repository to your computer

  git clone https://github.com/ozturkhuseyin/wch32_macos.git
  

• Change toolchain path for yourself in CH32V003F4P6_template project

  vim CH32V003F4P6_template/Makefile
  

• Then change the first line of Makefile for your toolchain path

  WCH_RV_TOOLCHAIN_DIR ?= /path/to/toolchain/directory
  

• Build CH32V003F4P6_template project

  cd CH32V003F4P6_template
  make all
  

• Connet WCH-Link to your board then your computer

  make flash_erase
  make flash_program
  make reset
  

  or just

  make upload_program
  

  this builds project, erases flash, programs flash then resets MCU.

TODO

• Add template projects for other development boards
• Add OpenOCD flashing
• Add GDB debug
• Make a VS Code extension
