Supported Features

The board configuration supports the following hardware features:

Peripheral	Kconfig option	Devicetree compatible
NVIC	N/A	arm,v7m-nvic
SYSTICK	N/A	N/A
USART	CONFIG_SERIAL	gd,gd32-usart

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.

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.

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

   west build -b gd32e103v_eval samples/hello_world
   

2. 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

3. To flash an image:

   west build -b gd32e103v_eval samples/hello_world
   west flash
   

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

4. To debug an image:

   west build -b gd32e103v_eval samples/hello_world
   west debug
   

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.
