Supported Features

The board configuration supports the following hardware features:

Peripheral	Kconfig option	Devicetree compatible
EXTI	CONFIG_GD32_EXTI	gd,gd32-exti
GPIO	CONFIG_GPIO	gd,gd32-gpio
NVIC	N/A	arm,v7m-nvic

Other peripherals may be used if shields are connected to the board.

Serial Port

The GD32F407V-START board has one serial communication port. The default port is USART0 with TX connected at PB6 and RX at PB7.

Programming and Debugging

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

• JP3/4: Select 2-3 for both (boot from user memory)

Using GD-Link or J-Link

The board comes with an embedded GD-Link programmer. You need to install CMSIS-Pack which is required by pyOCD when programming or debugging by the GD-Link programmer. Execute the following command to install CMSIS-Pack for GD32F407VK if not installed yet.

pyocd pack install gd32f407vk

Also, J-Link can be used to program the board via the SWD interface (PA13/SWDIO and PA14/SWCLK in the JP6 header).

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

   west build -b gd32f407v_start samples/hello_world
   

2. Connect Serial-USB adapter to PB6, PB7, and GND.

3. 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

4. To flash an image:

   west build -b gd32f407v_start samples/hello_world
   west flash
   

   When using J-Link, append --runner jlink option after west flash.

   You should see “Hello World! gd32f407v_start” in your terminal.

5. To debug an image:

   west build -b gd32f407v_start samples/hello_world
   west debug
   

   When using J-Link, append --runner jlink option after west debug.
