CH32V307_Template/README.md

Template for WCH CH32V30x series MCU

How to use

• Write your own CMake toolchain file (see riscv64-elf.cmake for example)
• Configure project and build as usual. (see below for a simple test)

Sample usage

mkdir build && cd build
cmake -DCMAKE_TOOLCHAIN_FILE=riscv64-elf.cmake ..
make -j${nprocs}

Notes

Startup files

There are two versions of startup assembly files, located at

• BSP/Startup/startup_ch32v30x_D8.S
• BSP/Startup/startup_ch32v30x_D8C.S

The first file is used for CH32V303 devices, which lacks of the following peripherals:

• Ethernet
• CAN2
• USBHS
• DVP

** Change the startup file to the correct version for the hardware in use. **
