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

The frdm_mcxe247 board supports the runners and associated west commands listed below.

	flash	debug	attach	debugserver	rtt
jlink	✅	✅	✅	✅	✅
linkserver	✅ (default)	✅ (default)	✅	✅

Build and flash applications as usual (see Building an Application and Run an Application 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 MCU-Link CMSIS-DAP 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.

Using J-Link

There are two options. The onboard debug circuit can be updated with Segger J-Link firmware by following the instructions in 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 J-Link 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.

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 Hello World application.

# From the root of the zephyr repository
west build -b frdm_mcxe247 samples/hello_world
west flash

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

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