NXP FRDM-MCXN947
################
Overview
********
FRDM-MCXN947 are compact and scalable development boards for rapid prototyping of
MCX N94 and N54 MCUs. They offer industry standard headers for easy access to the
MCUs I/Os, integrated open-standard serial interfaces, external flash memory and
an on-board MCU-Link debugger. 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/frdm_mcxn947/frdm_mcxn947_mcxn947_cpu0_defconfig`
only enables the first core.
Other hardware features are not currently supported by the port.`
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.
+------------+-----------------+----------------------------+
| Name | Function | Usage |
+============+=================+============================+
| P0_PIO1_8 | UART | UART RX |
+------------+-----------------+----------------------------+
| P1_PIO1_9 | UART | UART TX |
+------------+-----------------+----------------------------+
System Clock
============
The MCX-N947 SoC is configured to use PLL0 running at 150MHz as a source for
the system clock.
Serial Port
===========
The FRDM-MCXN947 SoC has 10 FLEXCOMM interfaces for serial communication.
Flexcomm 4 is configured as UART for the console.
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. Follow the instructions in
:ref:`mcu-link-cmsis-onboard-debug-probe` to progtam the MCU-Link firmware.
This only needs to be done if the default onboard debug circuit firmware was changed.
To put the board in ``DFU mode`` to program the firmware, short jumper J21.
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 put the board in ``DFU mode`` to program the firmware, short jumper J21.
The second option is to attach :ref:`jlink-external-debug-probe` to the
board.
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 J17, 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.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: frdm_mcxn947/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 v3.6.0-479-g91faa20c6741 ***
Hello World! frdm_mcxn947
Debugging
=========
Here is an example for the :ref:`hello_world` application.
.. zephyr-app-commands::
:zephyr-app: samples/hello_world
:board: frdm_mcxn947/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 v3.6.0-479-g91faa20c6741 ***
