Using J-Link

You need to use J-Link to program and debug the board via the SWD interface. (PA13/DIO and PA14/CLK). You need to install CMSIS-Pack which is required by pyOCD when programming or debugging by the GD-Link programmer. Execute the following command to install CMSIS-Pack for GD32F407VE if not installed yet.

pyocd pack install gd32f407ve

Build the Zephyr kernel and the Hello World sample application:
```
west build -b skystar_gd32f407vet6 samples/hello_world
```
Connect Serial-USB adapter to PA9, PA10, and GND.
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 skystar_gd32f407vet6 samples/hello_world
west flash
```
When using J-Link, append --runner jlink option after west flash.

You should see “Hello World! skystar_gd32f407vet6” in your terminal.
To debug an image:
```
west build -b skystar_gd32f407vet6 samples/hello_world
west debug
```
When using J-Link, append --runner jlink option after west debug.
