GigaDevice GD32L233R-EVA

Overview

The GD32L233R-EVAL board is a hardware platform that enables design and debug of the GigaDevice GD32L233 Cortex-M23 Low Power MCU.

The GD32RCT6 features a single-core ARM Cortex-M4F MCU which can run up to 64-MHz with flash accesses zero wait states, 256kB of Flash, 32kB of SRAM and 59 GPIOs.

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
SYSTICK	N/A	N/A
USART	CONFIG_SERIAL	gd,gd32-usart
PINMUX	CONFIG_PINCTRL	gd,gd32-pinctrl-af
ADC	CONFIG_ADC	gd,gd32-adc

Serial Port

The GD32L233R-EVAL board has one serial communication port. The default port is USART1 with TX connected at PA2 and RX at PA3. USART1 have connect to a CH04E serial connector with Mini-USB.

Programming and Debugging

Using J-Link

The GD32L233R-EVAL includes an onboard programmer/debugger (GD-Link) which allows flash programming and debugging over USB. There is also a SWD header which can be used with tools like Segger J-Link(latest version required).

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

   west build -b gd32l233r_eval 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 gd32l233r_eval samples/hello_world
   west flash
   

   You should see “Hello World! gd32l233r_eval” in your terminal.

4. To debug an image:

   west build -b gd32l233r_eval samples/hello_world
   west debug
