Supported Features

.. zephyr:board-supported-hw::

Connections and IOs

The MCX E247 SoC has five pairs of pinmux/gpio controllers (PORTA/GPIOA, PORTB/GPIOB, PORTC/GPIOC, PORTD/GPIOD, and PORTE/GPIOE).

System Clock

The MCXE247 SoC is configured to use SPLL running at 80 MHz (RUN mode) as a system clock source.

Serial Port

The MCX E247 LPUART2 is used for the console.

Programming and Debugging

.. zephyr:board-supported-runners::

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 DFU mode to program the firmware, short jumper JP2.

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 DFU mode by shortening the jumper JP2. The second option is to attach a :ref:jlink-external-debug-probe to the 10-pin SWD connector (J10) of the board. 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 J13, 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: frdm_mcxe247 :goals: flash

Open a serial terminal, reset the board (press the SW1 button), and you should see the following message in the terminal:

.. code-block:: console

*** Booting Zephyr OS build v4.1.0-5194-ge7d44ce91cb3 *** Hello World! frdm_mcxe247/mcxe247

Debugging

Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: frdm_mcxe247 :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 v4.1.0-5194-ge7d44ce91cb3 *** Hello World! frdm_mcxe247/mcxe247
