Serial Port

The GD32E103V-EVAL board has 5 serial communication ports. 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.

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 $HOME/.local/bin.

  1. Build the Zephyr kernel and the Hello World sample application:

    west build -b gd32e103v_eval samples/hello_world

  2. Enable board bootloader:

    • Remove boot-0 jumper

    • press reset button

  3. To flash an image:

    west build -b gd32e103v_eval samples/hello_world
west flash -r gd32isp [--port=/dev/ttyUSB0]

  4. Run your favorite terminal program to listen for output. Under Linux the terminal should be /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

    Press reset button

    You should see “Hello World! gd32e103v_eval” in your terminal.
