Overview

The GD32F450V-START board is a hardware platform that enables prototyping on GD32F450VK Cortex-M4F Stretch Performance MCU.

The GD32F450VK features a single-core ARM Cortex-M4F MCU which can run up to 200 MHz with flash accesses zero wait states, 3072kiB of Flash, 256kiB of SRAM and 82 GPIOs.

Hardware

• GD32F450VKT6 MCU

• 1 x User LEDs

• 1 x User Push buttons

• USB FS/HS connectors

• GD-Link on board programmer

• J-Link/SWD connector

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,v8m-nvic
PWM	CONFIG_PWM	gd,gd32-pwm
SYSTICK	N/A	N/A
USART	CONFIG_SERIAL	gd,gd32-usart

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

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.

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

   west build -b gd32f450v_start 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 gd32f450v_start samples/hello_world
   west flash
   

   You should see “Hello World! gd32f450v_start” in your terminal.

4. To debug an image:

   west build -b gd32f450v_start samples/hello_world
   west debug
