Overview
|
|
********
|
|
|
|
The GD32VF103C-STARTER board is a hardware platform that enables prototyping
|
|
on GD32VF103CB RISC-V MCU.
|
|
|
|
The GD32VF103CB features a single-core RISC-V 32-bit MCU which can run up
|
|
to 108 MHz with flash accesses zero wait states, 128 KiB of Flash, 32 KiB of
|
|
SRAM and 37 GPIOs.

Serial Port
|
|
===========
|
|
|
|
The GD32VF103C-STARTER board has one serial communications port.
|
|
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:
|
|
|
|
- JP2/3: Select 2-3 for both (boot from user memory)
|
|
- JP5/6: Select 1-2 positions (labeled as ``USART0``)
|
|
|
|
Using GD-Link
|
|
=============
|
|
|
|
The GD32VF103C-STARTER includes an onboard programmer/debugger (GD-Link) which
|
|
allows flash programming and debugging over USB. There is also a JTAG header
|
|
(JP1) 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: gd32vf103c_starter
|
|
: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: gd32vf103c_starter
|
|
:goals: flash
|
|
:compact:
|
|
|
|
You should see "Hello World! gd32vf103c_starter" in your terminal.
|
|
|
|
#. To debug an image:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: gd32vf103c_starter
|
|
:goals: debug
