Programming & Debugging

The pic32ck_sg01_cult board supports the runners and associated west commands listed below.

	flash	debug	attach	debugserver	rtt	reset
jlink	✅	✅ (default)	✅	✅	✅	✅
mplab_ipe	✅ (default)

Flash Using MPLAB IPE

For instructions on flashing using MPLAB IPE see Flashing with Microchip MPLAB IPE.

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 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 pic32ck_sg01_cult -p samples/basic/blinky
```
This will build the Blinky application for the pic32ck_sg01_cult board.
Flash the Device

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

After flashing, LED0 on the board should start blinking, indicating that the application is running successfully.

Debug Using J-Link: GDB Command-Line

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

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 pic32ck_sg01_cult -p samples/basic/blinky
```
This will build the Blinky application for the pic32ck_sg01_cult board.

Debug the Application

To debug the application, run the following command from your Zephyr workspace:

west debug

Note

Debugging with J-Link GDB Server: Halting at `main` and Setting Breakpoints

(gdb) break main
(gdb) break main.c:42         # Optional: set breakpoint at line 42 in main.c
(gdb) continue                # Start execution, halts at first breakpoint
(gdb) info breakpoints        # List all breakpoints
(gdb) delete 1                # Delete breakpoint number 1
(gdb) delete                  # Delete all breakpoints
(gdb) clear main.c:42         # Clear breakpoint at specific location
(gdb) continue                # Resume execution

Debug Using J-Link: VSCode

To debug using VSCode, create or edit the .vscode/launch.json file in your project directory with the following configuration:
