RISC-V Embedded GCC
Standard RISC-V gcc, you can replace it with a newer version from https://github.com/xpack-dev-tools/riscv-none-embed-gcc-xpack/releases. Extract it to /opt/gcc-riscv
OpenOCD
A customized OpenOCD for WCH-Link, Extract it to /opt/openocd
Run start.sh under beforeinstall, or manually setup the udev rules and the dynamic lib files. You can run the following command with EVB and WCH-Link connected
./openocd -f wch-riscv.cfg -c init -c haltif everything goes correctly
