Overview

The WCH_ CH32V006EVT is an evaluation board for the RISC-V based CH32V006K8U6 SOC.

The board is equipped with a power LED, reset button, USB port for power, and two user LEDs. The WCH webpage on CH32V006_ contains the processor's information and the datasheet.

Hardware

The QingKe V2C 32-bit RISC-V processor of the WCH CH32V006EVT is clocked by an external crystal and runs at 48 MHz.

Supported Features

Connections and IOs

LED

LED1 = Unconnected. Connect to an I/O pin (PD0).
LED2 = Unconnected. Connect to an I/O pin (PC0).

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the ch32v006evt board can be built and flashed in the usual way (see :ref:build_an_application and :ref:application_run for more details); however, an external programmer is required since the board does not have any built-in debug support.

Connect the programmer to the following pins on the PCB:

VCC = VCC (do not power the board from the USB port at the same time)
GND = GND
SWIO = PD1

Flashing

You can use minichlink_ to flash the board. Once minichlink has been set up, build and flash applications as usual (see :ref:build_an_application and :ref:application_run for more details).

Here is an example for the :zephyr:code-sample:blinky application.

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: ch32v006evt :goals: build flash

Debugging

This board can be debugged via OpenOCD or minichlink.

Testing the LED on the WCH CH32V006EVT

The blinky sample can be used to test that the LEDs on the board are working properly with Zephyr:

:zephyr:code-sample:blinky

You can build and flash the examples to make sure Zephyr is running correctly on your board. The LED definitions can be found in :zephyr_file:boards/wch/ch32v006evt/ch32v006evt.dts.
