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.

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 ***
