.. zephyr:board:: ch32v307v_evt_r1

Overview

The WCH_ CH32V307V-EVT-R1 is an evaluation board for the RISC-V based CH32V307VCT6 SOC.

The board is equipped with a power LED, reset button, USB port for power, and two user LEDs. It also features Ethernet port and built-in programmer.

Hardware

The QingKe V4F 32-bit RISC-V processor of the WCH CH32V307V-EVT-R1 is clocked by an external crystal and runs at 144 MHz.

The WCH webpage on CH32V30x_ contains the processor's information and the datasheet. WCH CH32V307V-EVT-R1 board schematics can be found on CH32V307 openwch git repository_.

Connections and IOs

LED

Board LEDs are not connected to SoC in layout. For blinky and threads sample applications you have to use jumper wires to connect them to I/O pins. You also need to change leds status to "okay" in :zephyr_file:boards/wch/ch32v307v_evt_r1/ch32v307v_evt_r1.dts.

Programming and Debugging

.. zephyr:board-supported-runners::

Applications for the ch32v307v_evt_r1 board can be built and flashed in the usual way (see :ref:build_an_application and :ref:application_run for more details). The board includes WCH LinkE_ programmer accessible on USB-C port P9.

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: ch32v307v-evt-r1 :goals: build flash

Or you can use :zephyr:code-sample:multi-thread-blinky sample to test both LEDs.

Debugging

This board can be debugged via minichlink.
