GigaDevice GD32F350R-EVAL
#########################
Overview
********
The GD32F350R-EVAL board is a hardware platform that enables design and debug
of the GigaDevice F350 Cortex-M4F High Performance MCU.
The GD32F350RBT6 features a single-core ARM Cortex-M4F MCU which can run up
to 108-MHz with flash accesses zero wait states, 128kB of Flash, 16kB of
SRAM and 55 GPIOs.

Serial Port
===========
The GD32F350R-EVAL board has one serial communication port. The default port
is USART0 with TX connected at PA9 and RX at PA10.
Programming and Debugging
*************************
Before programming your board make sure to configure boot and serial jumpers as follows:
- J4: Select 2-3 for both (labeled as ``L``)
- J13: Select 1-2 position (labeled as ``USART``)
Using GD-Link
=============
The GD32F350R-EVAL includes an onboard programmer/debugger (GD-Link) which
allows flash programming and debugging over USB. There is also a SWD header
(J3) which can be used with tools like Segger J-Link.
#. Build the Zephyr kernel and the :ref:`hello_world` sample application:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: gd32f350r_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: gd32f350r_eval
:goals: flash
:compact:
You should see "Hello World! gd32f350r_eval" in your terminal.
#. To debug an image:
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: gd32f350r_eval
:goals: debug
