Overview

The GD32E507V-START board is a hardware platform that enables prototyping on GD32E507VE Cortex-M33 High Performance MCU.

The GD32E507VE features a single-core ARM Cortex-M33 MCU which can run up to 180 MHz with flash accesses zero wait states, 512kiB of Flash, 128kiB of SRAM and 80 GPIOs.

Hardware

  • GD32E507VET6 MCU
  • 1 x User LEDs
  • 1 x User Push buttons
  • 1 x USART (RS-232 at J1 connector)
  • GD-Link on board programmer
  • J-Link/SWD connector

Serial Port

The GD32E507V-START board has one serial communication port. The default port is USART0 with TX connected at PB6 and RX at PB7. USART0 is exposed as a virtual COM port via the CN3 USB connector.

Programming and Debugging

.. zephyr:board-supported-runners::

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

  • JP3/4: Select 2-3 for both (boot from user memory)

Using GD-Link or J-Link

The board comes with an embedded GD-Link programmer. It can be used with pyOCD provided you install the necessary CMSIS-Pack:

.. code-block:: console

pyocd pack install gd32e507ve

J-Link can also be used to program the board using the SWD interface exposed in the JP1 header.

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

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32e507v_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: gd32e507v_start :goals: flash :compact:

You should see "Hello World! gd32e507v_start" in your terminal.
