The default port is UART0 at PIN-9 and PIN-10. Programming and Debugging ************************* Before program your board make sure to configure boot setting and serial port. The default serial port is USART0. This port uses header JP-5/6 to route signals between USB VBUS/ID and USART J2. +--------+--------+------------+ | Boot-0 | Boot-1 | Function | +========+========+============+ | 1-2 | 1-2 | SRAM | +--------+--------+------------+ | 1-2 | 2-3 | Bootloader | +--------+--------+------------+ | 2-3 | Any | Flash | +--------+--------+------------+ +------+------+-------------+ | JP-5 | JP-6 | Function | +======+======+=============+ | 1-2 | 1-2 | USART0 / J2 | +------+------+-------------+ | 2-3 | 2-3 | USB VBUS/ID | +------+------+-------------+ | open | open | Free | +------+------+-------------+ Using GD-Link ============= The GD32E103V-EVAL includes an onboard programmer/debugger (GD-Link) which allow flash programming and debug over USB. There are also program and debug headers J1 and J100 that can be used with any ARM compatible tools. #. Build the Zephyr kernel and the :ref:`hello_world` sample application: .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32e103v_eval :goals: build :compact: #. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:`/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: gd32e103v_eval :goals: flash :compact: You should see "Hello World! gd32e103v_eval" in your terminal. #. To debug an image: .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32e103v_eval :goals: debug :compact: Using ROM bootloader ==================== The GD32E103 MCU have a ROM bootloader which allow flash programming. User should install `GD32 ISP Console`_ software at some Linux path. The recommended is :code:`$HOME/.local/bin`. #. Build the Zephyr kernel and the :ref:`hello_world` sample application: .. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: gd32e103v_eval :goals: build :compact: #. Enable board bootloader: - Remove boot-0 jumper - press reset button #. To flash an image: .. code-block:: console west build -b gd32e103v_eval samples/hello_world west flash -r gd32isp [--port=/dev/ttyUSB0] #. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:`/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 Press reset button You should see "Hello World! gd32e103v_eval" in your terminal. .. _GigaDevice Cortex-M4F High Performance SoC Website: https://www.gigadevice.com/products/microcontrollers/gd32/arm-cortex-m4/value-line/gd32e103-series/ .. _GD32E103 Datasheet: http://www.gd32mcu.com/download/down/document_id/235/path_type/1 .. _GD32E103 Reference Manual: http://www.gd32mcu.com/download/down/document_id/163/path_type/1 .. _GD32E103V Eval Schematics: http://www.gd32mcu.com/download/down/document_id/178/path_type/1 .. _GD32 ISP Console: http://www.gd32mcu.com/download/down/document_id/175/path_type/1
