LED2 = Unconnected. Connect to an I/O pin (PC0).
Programming and Debugging
The ch32v006evt board supports the runners and associated west commands listed below.
| flash | debug | rtt | debugserver | attach | |
|---|---|---|---|---|---|
| minichlink | ✅ (default) | ||||
| openocd | ✅ | ✅ (default) | ✅ | ✅ | ✅ |
Applications for the ch32v006evt board can be built and flashed
in the usual way (see Building an Application and Run an Application
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 [3] 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 Blinky application.
# From the root of the zephyr repository
west build -b ch32v006evt samples/basic/blinky
west 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:
You can build and flash the examples to make sure Zephyr is running correctly on your board. The LED definitions can be found in boards/wch/ch32v006evt/ch32v006evt.dts.
