.. zephyr:board:: gd32vf103v_eval

Overview

The GD32V103V-EVAL board is a hardware platform that enables prototyping on GD32VF103VB RISC-V MCU.

The GD32VF103VB features a single-core RISC-V 32-bit MCU which can run up to 108 MHz with flash accesses zero wait states, 128 KiB of Flash, 32 KiB of SRAM and 80 GPIOs.

Supported Features

.. zephyr:board-supported-hw::

Serial Port

The GD32VF103V-EVAL board has two serial communications 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:

• JP2/3: Select 2-3 for both (boot from user memory)
• JP5/6: Select 1-2 positions (labeled as USART0)

Using GD-Link

The GD32VF103V-EVAL includes an onboard programmer/debugger (GD-Link) which allows flash programming and debugging over USB. There is also a JTAG header (JP1) 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: gd32vf103v_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: gd32vf103v_eval :goals: flash :compact:

You should see "Hello World! gd32vf103v_eval" in your terminal.
