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

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

.. zephyr:board-supported-runners::

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 :zephyr:code-sample:hello_world sample application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32f450v_start :goals: build :compact:

#. Run your favorite terminal program to listen for output. On Linux the terminal should be something like /dev/ttyUSB0. For example:

.. code-block:: console

  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:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32f450v_start :goals: flash :compact:

You should see "Hello World! gd32f450v_start" in your terminal.

#. To debug an image:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32f450v_start :goals: debug :compact:
