Overview

The GD32E103V-EVAL board is a hardware platform that enables design and debug of the GigaDevice E103 Cortex-M4F High Performance MCU.

The GD32E103VB features a single-core ARM Cortex-M4F MCU which can run up to 120-MHz with flash accesses zero wait states, 128kiB of Flash, 32kiB of SRAM and 80 GPIOs.

Hardware

  • USB interface with mini-USB connector

  • 4 user LEDs

  • 4 user push buttons

  • Reset Button

  • ADC connected to a potentiometer

  • 2 DAC channels

  • GD25Q16 2Mib SPI Flash

  • AT24C02C 2KiB EEPROM

  • 3.2 TFT LCD (320x240)

Supported Features

.. zephyr:board-supported-hw::

Serial Port

The GD32E103V-EVAL board has 5 serial communication ports. The default port is UART0 at PIN-9 and PIN-10.

Programming and Debugging

.. zephyr:board-supported-runners::

Before program your board make sure to configure boot setting and serial port. The default serial port is USART0. This port uses header JP-5/6 to route signals between USB VBUS/ID and USART J2.

+--------+--------+------------+ | Boot-0 | Boot-1 | Function | +========+========+============+ | 1-2 | 1-2 | SRAM | +--------+--------+------------+ | 1-2 | 2-3 | Bootloader | +--------+--------+------------+ | 2-3 | Any | Flash | +--------+--------+------------+

Using GD-Link

The GD32E103V-EVAL includes an onboard programmer/debugger (GD-Link) which allow flash programming and debug over USB. There are also program and debug headers J1 and J100 that can be used with any ARM compatible tools.

#. Build the Zephyr kernel and the :zephyr:code-sample:hello_world sample application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32e103v_eval :goals: build :compact:

#. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:/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: gd32e103v_eval :goals: flash :compact:

You should see "Hello World! gd32e103v_eval" in your terminal.

#. To debug an image:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32e103v_eval :goals: debug :compact:

Using ROM bootloader

The GD32E103 MCU have a ROM bootloader which allow flash programming. User should install GD32 ISP Console_ software at some Linux path. The recommended is :code:$HOME/.local/bin.

#. Build the Zephyr kernel and the :zephyr:code-sample:hello_world sample application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32e103v_eval :goals: build :compact:

#. Enable board bootloader:

  • Remove boot-0 jumper
  • press reset button

#. To flash an image:

.. code-block:: console

  west build -b gd32e103v_eval samples/hello_world
  west flash -r gd32isp [--port=/dev/ttyUSB0]

#. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:/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

Press reset button

You should see "Hello World! gd32e103v_eval" in your terminal.
