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.

Build the Zephyr kernel and the Hello World sample application:
```
west build -b gd32f350r_eval samples/hello_world
```
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
To flash an image:
```
west build -b gd32f350r_eval samples/hello_world
west flash
```
You should see “Hello World! gd32f350r_eval” in your terminal.

To debug an image:

west build -b gd32f350r_eval samples/hello_world
west debug
