Serial Port
The GD32F450V-START board has no exposed serial communication port. The board provides default configuration for USART0 with TX connected at PB6 and RX at PB7. PB6/PB7 are exposed in JP6, so you can solder a connector and use a UART-USB adapter.
Programming and Debugging
Before programming your board make sure to configure boot jumpers as follows:
JP2/3: Select 2-3 for both (boot from user memory)
Using GD-Link
The GD32F450V-START includes an onboard programmer/debugger (GD-Link) which allows flash programming and debugging over USB. There is also a SWD header (JP100) which can be used with tools like Segger J-Link.
Build the Zephyr kernel and the Hello World sample application:
west build -b gd32f450v_start 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 gd32f450v_start samples/hello_world west flash
You should see “Hello World! gd32f450v_start” in your terminal.
To debug an image:
west build -b gd32f450v_start samples/hello_world west debug
