Supported Features
The board configuration supports the following hardware features:
| Peripheral | Kconfig option | Devicetree compatible | 
|---|---|---|
| EXTI | ||
| GPIO | ||
| NVIC | N/A | |
| PWM | ||
| SYSTICK | N/A | N/A |

Serial Port
The GD32E507V-START board has one serial communication port. The default port is USART0 with TX connected at PB6 and RX at PB7. USART0 is exposed as a virtual COM port via the CN3 USB connector.
Programming and Debugging
Before programming your board make sure to configure boot jumpers as follows:
- JP3/4: Select 2-3 for both (boot from user memory) 
Using GD-Link or J-Link
The board comes with an embedded GD-Link programmer. It can be used with pyOCD provided you install the necessary CMSIS-Pack:
pyocd pack install gd32e507ve
J-Link can also be used to program the board using the SWD interface exposed in the JP1 header.
- Build the Zephyr kernel and the Hello World sample application: - west build -b gd32e507v_start samples/hello_world 
- Run your favorite terminal program to listen for output. On Linux the terminal should be something like - /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 
 
- To flash an image: - west build -b gd32e507v_start samples/hello_world west flash - You should see “Hello World! gd32e507v_start” in your terminal. 
- To debug an image: - west build -b gd32e507v_start samples/hello_world west debug
