Supported Features

The board configuration supports the following hardware features:

Peripheral	Kconfig option	Devicetree compatible
NVIC	N/A	arm,v7m-nvic
SYSTICK	N/A	N/A
USART	CONFIG_SERIAL	gd,gd32-usart
PINMUX	CONFIG_PINCTRL	gd,gd32-pinctrl-af

Serial Port

The GD32F350R-EVAL board has one serial communication port. The default port is USART0 with TX connected at PA9 and RX at PA10.

Programming and Debugging

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

• J4: Select 2-3 for both (labeled as L)

• J13: Select 1-2 position (labeled as USART)

Using GD-Link

The GD32F350R-EVAL includes an onboard programmer/debugger (GD-Link) which allows flash programming and debugging over USB. There is also a SWD header (J3) which can be used with tools like Segger J-Link.

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

   west build -b gd32f350r_eval 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 gd32f350r_eval samples/hello_world
   west flash
   

   You should see “Hello World! gd32f350r_eval” in your terminal.

4. To debug an image:

   west build -b gd32f350r_eval samples/hello_world
   west debug
