Serial Port

The GD32VF103C-STARTER board has one serial communications port. TX connected at PA9 and RX at PA10.

Programming and Debugging

The gd32vf103c_starter board supports the runners and associated west commands listed below.

	flash	debug	rtt	debugserver	attach
jlink	✅	✅	✅	✅	✅
openocd	✅ (default)	✅ (default)	✅	✅	✅

Before programming your board make sure to configure boot and serial jumpers as follows:

• JP2/3: Select 2-3 for both (boot from user memory)

• JP5/6: Select 1-2 positions (labeled as USART0)

Using GD-Link

The GD32VF103C-STARTER includes an onboard programmer/debugger (GD-Link) which allows flash programming and debugging over USB. There is also a JTAG header (JP1) which can be used with tools like Segger J-Link.

1. Build the Zephyr kernel and the Hello World sample application:

   west build -b gd32vf103c_starter samples/hello_world
   

2. Run your favorite terminal program to listen for output. On Linux the terminal should be something like /dev/ttyUSB0. For example:

   minicom -D /dev/ttyUSB0 -o
   

   The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:

   • Speed: 115200

   • Data: 8 bits

   • Parity: None

   • Stop bits: 1

3. To flash an image:

   west build -b gd32vf103c_starter samples/hello_world
   west flash
   

   You should see “Hello World! gd32vf103c_starter” in your terminal.

4. To debug an image:

   west build -b gd32vf103c_starter samples/hello_world
   west debug
