+
+MCX-N9XX-EVK is a full featured evaluation kit for prototyping of MCX N94 / N54
+MCUs. They offer industry standard headers for access to the MCU’s I/Os,
+integrated open-standard serial interfaces and an on-board MCU-Link debugger
+with power measurement capability.  MCX N Series are high-performance, low-power
+microcontrollers with intelligent peripherals and accelerators providing
+multi-tasking capabilities and performance efficiency.

+Targets available
+==================
+
+The default configuration file
+:zephyr_file:`boards/nxp/mcx_n9xx_evk/mcx_n9xx_evk_mcxn947_cpu0_defconfig`
+only enables the first core. CPU0 is the only target that can run standalone.
+
+CPU1 does not work without CPU0 enabling it.
+
+To enable CPU1, create System Build application project and enable the
+second core with config :kconfig:option:`CONFIG_SECOND_CORE_MCUX`.
+
+Please have a look at some already enabled samples:
+
+- :zephyr:code-sample:`ipc-static-vrings`
+- :zephyr:code-sample:`openamp`
+- :zephyr:code-sample:`mbox`
+- :zephyr:code-sample:`mbox_data`
+
+Connections and IOs
+===================
+
+The MCX-N947 SoC has 6 gpio controllers and has pinmux registers which
+can be used to configure the functionality of a pin.
+

+------------+-----------------+----------------------------+
+
+System Clock
+============
+
+The MCX-N947 SoC is configured to use PLL0 running at 150MHz as a source for
+the system clock.
+
+Serial Port
+===========
+
+The MCX-N9XX-EVK SoC has 10 FLEXCOMM interfaces for serial communication.
+Flexcomm 4 is configured as UART for the console.
+
+Ethernet
+========
+To use networking samples with the Ethernet jack, change jumper JP13 to pins 2-3.
+
+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 MCU-Link CMSIS-DAP Onboard Debug Probe.
+
+Using LinkServer
+----------------
+
+LinkServer is the default runner for this board, and supports the factory
+default MCU-Link firmware. Follow the instructions in
+:ref:`mcu-link-cmsis-onboard-debug-probe` to reprogram the default MCU-Link
+firmware. This only needs to be done if the default onboard debug circuit
+firmware was changed. To put the board in ``ISP mode`` to program the firmware,
+short jumper JP24.
+
+Using J-Link
+------------
+
+There are two options. The onboard debug circuit can be updated with Segger
+J-Link firmware by following the instructions in
+:ref:`mcu-link-jlink-onboard-debug-probe`.
+To be able to program the firmware, you need to put the board in ``ISP mode``
+by shortening the jumper JP24.
+The second option is to attach a :ref:`jlink-external-debug-probe` to the
+20-pin SWD connector (J11) of the board. Additionally, the jumper JP6 must
+be shorted.
+For both options use the ``-r jlink`` option with west to use the jlink runner.
+
+.. code-block:: console
+
+   west flash -r jlink
+
+Configuring a Console
+=====================
+
+Connect a USB cable from your PC to J5, 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 :zephyr:code-sample:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: mcx_n9xx_evk/mcxn947/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 build vX.X.X ***
+   Hello World! mcx_n9xx_evk/mcxn947/cpu0
+
+Building a dual-core image
+==========================
+
+The dual-core samples are run using ``mcx_n9xx_evk/mcxn947/cpu0`` target.
+
+Images built for ``mcx_n9xx_evk/mcxn947/cpu1`` will be loaded from flash
+and executed on the second core when :kconfig:option:`CONFIG_SECOND_CORE_MCUX` is selected.
+
+For an example of building for both cores with System Build, see
+:zephyr:code-sample:`ipc-static-vrings`
+
+Here is an example for the :zephyr:code-sample:`mbox_data` application.
+
+.. zephyr-app-commands::
+   :app: zephyr/samples/drivers/mbox_data
+   :board: mcx_n9xx_evk/mcxn947/cpu0
+   :goals: flash
+   :west-args: --sysbuild
+
+Flashing to QSPI
+================
+
+In order to load Zephyr application from QSPI, program a bootloader like
+MCUboot bootloader to internal flash. Here are the steps for the
+:zephyr:code-sample:`hello_world` application.
+
+.. zephyr-app-commands::
+   :app: zephyr/samples/hello_world
+   :board: mcx_n9xx_evk/mcxn947/cpu0/qspi
+   :gen-args: --sysbuild -- -DSB_CONFIG_BOOTLOADER_MCUBOOT=y
+   :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 MCUboot vX.X.X ***
+  *** Using Zephyr OS build vX.X.X ***
+  I: Starting bootloader
+  I: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3
+  I: Secondary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x3
+  I: Boot source: none
+  I: Image index: 0, Swap type: none
+  I: Bootloader chainload address offset: 0x0
+  I: Jumping to the first image slot
+  *** Booting Zephyr OS build vX.X.X ***
+  Hello World! mcx_n9xx_evk/mcxn947/cpu0/qspi
+
+Debugging
+=========
+
+Here is an example for the :zephyr:code-sample:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: mcx_n9xx_evk/mcxn947/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 build vX.X.X ***
+   Hello World! mcx_n9xx_evk/mcxn947/cpu0
+
+Debugging a dual-core image
+---------------------------
+
+For dual core builds, the secondary core should be placed into a loop,
+then a debugger can be attached.
+As a reference please see (`AN13264`_, section 4.2.3 for more information).
+The reference is for the RT1170 but similar technique can be also used here.

+SAI peripheral by shorting signals externally on the EVK.  These are the HW changes
