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
