Hardware requirements

  • USB-C cable

  • Loopback network cable RJ45 standard

  • FRDM-MCXE247 board

  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a USB cable between the host PC and the MCU-LINK USB port on the target board.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Insert loopback network cable to Ethernet RJ45 port.

  4. Download the program to the target board.

  5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Make loopback network cable:

      568B standard 	 Unknown standard
J1    orange+white       green+white
J2    orange             green
J3    green+white        orange+white
J4    blue               brown+white
J5    blue+white         brown
J6    green              orange
J7	  brown+white        blue
J8    brown              blue+white

Connect J1 => J3, J2 => J6, J4 => J7, J5 => J8. 10/100M transfer only requires J1, J2, J3, J6, and 1G transfer requires all 8 pins. Check your net cable color order and refer to 568B standard or the other standard. If your cable’s color order is not shown in the list, please connect J1~J8 based on your situation.
