Supported Features

.. zephyr:board-supported-hw::

Serial Port

The GD32F450I-EVAL board has one serial communication port. The default port is USART0 with TX connected at PA9 and RX at PA10.

Programming and Debugging

.. zephyr:board-supported-runners::

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

• J2/3: Select 2-3 for both (boot from user memory)
• J5: Select 1-2 position (labeled as USART0)

Using GD-Link

The GD32F450I-EVAL includes an onboard programmer/debugger (GD-Link) which allows flash programming and debugging over USB. There is also a JTAG header (J1) 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: gd32f450i_eval :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: gd32f450i_eval :goals: flash :compact:

You should see "Hello World! gd32f450i_eval" in your terminal.
