Hardware requirements

  • Mini/micro USB cable

  • MCX-N5XX-EVK board

  • Personal Computer

  • Loopback network cable RJ45 standard

Board settings

Set JP13 2-3 on. Populate R274 to sync reference clock.

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA 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 Unknowed 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 showed in the list, please connect J1~J8 based on your situation.
