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 :zephyr:code-sample:`hello_world` sample application:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: gd32l233r_eval
|
|
: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: gd32l233r_eval
|
|
:goals: flash
|
|
:compact:
|
|
|
|
You should see "Hello World! gd32l233r_eval" in your terminal.
|
|
|
|
#. To debug an image:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: gd32l233r_eval
|
|
:goals: debug
