Flash Using J-Link

To flash the board using the J-Link debugger, follow the steps below:

Install J-Link Software
- Download and install the J-Link software tools from Segger.
- Make sure the installed J-Link executables (e.g., JLink, JLinkGDBServer) are available in your system’s PATH.
Connect the Board
- Connect the J32 Debug Probe to the board’s CORTEX DEBUG (J400) header.
- Connect the other end of the J32 Debug Probe to your host machine (PC) via USB.
- Connect the DEBUG USB port on the board to your host machine to power up the board.
Build the Application

You can build a sample Zephyr application, such as Blinky, using the west tool. Run the following commands from your Zephyr workspace:
```
west build -b pic32cx_sg41_cult -p -s samples/basic/blinky
```
This will build the Blinky application for the pic32cx_sg41_cult board.
Flash the Device

Once the build completes, flash the firmware using:
```
west flash
```
This uses the default jlink runner to flash the application to the board.
Observe the Result

After flashing, LED1 on the board should start blinking, indicating that the application is running successfully.
