+Overview
+********
+
+The PIC32CM JH01 Curiosity Pro evaluation kit is a hardware platform
+to evaluate the Microchip PIC32CM JH01 microcontroller, and the
+evaluation kit part number is EV81X90A. The evaluation kit offers a
+set of features that enables the PIC32CM JH01 users to get started with
+the PIC32CM JH01 peripherals, and to obtain an understanding of how to
+integrate the device in their own design.
+
+Hardware

+
+Flash Using J-Link
+==================
+
+To flash the board using the J-Link debugger, follow the steps below:
+
+1. 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.
+
+2. 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**.
+
+3. 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:
+
+   .. code-block:: console
+
+      west build -b pic32cm_jh01_cpro -p -s samples/basic/blinky
+
+   This will build the Blinky application for the ``pic32cm_jh01_cpro`` board.
+
+4. Flash the Device
+
+   Once the build completes, flash the firmware using:
+
+   .. code-block:: console
+
+      west flash
+
+   This uses the default ``jlink`` runner to flash the application to the board.
+
+5. Observe the Result
+
+   After flashing, **LED0** on the board should start **blinking**, indicating that the
+   application is running successfully.
