Programming and Debugging
Applications for the ch32v303vct6_evt board target can be built and flashed
in the usual way (see Building an Application and Run an Application
for more details); however, an external programmer (like the WCH LinkE [3]) is required since the board
does not have any built-in debug support.
Flashing
You can use minichlink to flash the board. Once minichlink has been set
up, build and flash applications as usual (see Building an Application and
Run an Application for more details).
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b ch32v303vct6_evt samples/hello_world
west flash
Debugging
This board can be debugged via OpenOCD using the WCH openOCD liberated fork, available at https://github.com/jnk0le/openocd-wch.
