GigaDevice GD32E507V-START

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

Supported Features

The board configuration supports the following hardware features:

Peripheral	Kconfig option	Devicetree compatible
EXTI	CONFIG_GD32_EXTI	gd,gd32-exti
GPIO	CONFIG_GPIO	gd,gd32-gpio
NVIC	N/A	arm,v8m-nvic
PWM	CONFIG_PWM	gd,gd32-pwm
SYSTICK	N/A	N/A
USART	CONFIG_SERIAL	gd,gd32-usart

Other peripherals may be used if shields are connected to the board.

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

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:

pyocd pack install gd32e507ve

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

1. Build the Zephyr kernel and the Hello World sample application:

   west build -b gd32e507v_start samples/hello_world
   

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

   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

3. To flash an image:

   west build -b gd32e507v_start samples/hello_world
   west flash
   

   You should see “Hello World! gd32e507v_start” in your terminal.

4. To debug an image:

   west build -b gd32e507v_start samples/hello_world
   west debug
