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.

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).
Build the Zephyr kernel and the Hello World sample application:
west build -b gd32l233r_eval samples/hello_world
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
To flash an image:
west build -b gd32l233r_eval samples/hello_world west flash
You should see “Hello World! gd32l233r_eval” in your terminal.
To debug an image:
west build -b gd32l233r_eval samples/hello_world west debug
