This example demonstrates how to use the semihosting feature of the RISCV using a customized openocd port from WCH's openocd sources.
- See my blog for more information.
- Clone my patched openocd repository
git clone --recursive [email protected]:treideme/openocd-hacks.git
cd openocd-hacks
./bootstrap
./configure --enable-wlinke \
--disable-ch347 \
--prefix=/opt/wch-riscv-openocd/ \
--program-prefix=wch-riscv- \
--disable-werror
make
sudo make install
# test installation
/opt/wch-riscv-openocd/bin/wch-riscv-openocd --version- Install WCH's toolchain
- Make sure it is in path
- Install meson and ninja
# Configure the build
meson setup --cross-file cross.ini -Dbuildtype=debug build
# Build
ninja -C build
# Try semihosting IO with target
/opt/wch-riscv-openocd/bin/wch-riscv-openocd -f flash.cfg
