+Overview
+********
+
+The LPCXpresso55S69 development board provides the ideal platform for evaluation
+of and development with the LPC55S6x MCU based on the Arm® Cortex®-M33
+architecture. The board includes a high performance onboard debug probe, audio
+subsystem, and accelerometer, with several options for adding off-the-shelf
+add-on boards for networking, sensors, displays, and other interfaces.

+
+The default configuration file
+``boards/arm/lpcxpresso55s69/lpcxpresso55s69_cpu0_defconfig``
+only enables the first core.
+
+Other hardware features are not currently supported by the port.
+
+Connections and IOs
+===================
+
+The LPC55S69 SoC has IOCON registers, which can be used to configure the
+functionality of a pin.
+
++---------+-----------------+----------------------------+
+| Name    | Function        | Usage                      |
++=========+=================+============================+

++---------+-----------------+----------------------------+
+
+System Clock
+============
+
+The LPC55S69 SoC is configured to use the internal FRO at 96MHz as a source for
+the system clock. Other sources for the system clock are provided in the SOC,
+depending on your system requirements.
+
+Serial Port
+===========
+
+The LPC55S69 SoC has 8 FLEXCOMM interfaces for serial communication.  One is
+configured as USART for the console and the remaining are not used.
+
+Programming and Debugging
+*************************
+
+Build and flash applications as usual (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+Configuring a Debug Probe
+=========================
+
+A debug probe is used for both flashing and debugging the board. This board is
+configured by default to use the LPC-Link2 CMSIS-DAP Onboard Debug Probe,
+however the :ref:`pyocd-debug-host-tools` does not yet support this probe so you
+must reconfigure the board for one of the following debug probes instead.
+
+:ref:`lpclink2-jlink-onboard-debug-probe`
+-----------------------------------------
+
+Install the :ref:`jlink-debug-host-tools` and make sure they are in your search
+path.
+
+Follow the instructions in :ref:`lpclink2-jlink-onboard-debug-probe` to program
+the J-Link firmware. Please make sure you have the latest firmware for this
+board.
+
+:ref:`opensda-daplink-onboard-debug-probe`
+------------------------------------------
+
+PyOCD support for this board is ongoing and not yet available.
+To use DAPLink's flash memory programming on this board, follow the instructions
+for `updating LPCXpresso firmware`_.
+
+Configuring a Console
+=====================
+
+Connect a USB cable from your PC to P6, and use the serial terminal of your choice
+(minicom, putty, etc.) with the following settings:
+
+- Speed: 115200
+- Data: 8 bits
+- Parity: None
+- Stop bits: 1
+
+Flashing
+========
+
+Here is an example for the :ref:`hello_world` application. This example uses the
+:ref:`jlink-debug-host-tools` as default.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: lpcxpresso55s69_cpu0
+   :goals: flash
+
+Open a serial terminal, reset the board (press the RESET button), and you should
+see the following message in the terminal:
+
+.. code-block:: console
+
+   ***** Booting Zephyr OS v1.14.0 *****
+   Hello World! lpcxpresso55s69_cpu0
+
+Debugging
+=========
+
+Here is an example for the :ref:`hello_world` application. This example uses the
+:ref:`jlink-debug-host-tools` as default.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: lpcxpresso55s69_cpu0
+   :goals: debug
+
+Open a serial terminal, step through the application in your debugger, and you
+should see the following message in the terminal:
+
+.. code-block:: console
+
+   ***** Booting Zephyr OS zephyr-v1.14.0 *****
