Hardware requirements

  • Micro USB cable

  • EVK-MIMXRT595 REV C1 board

  • Personal Computer

Board settings

Make sure resistors R691~R697 are removed and resistors R611~R620,R660,R661,R698 are populated.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J40) on the 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. Download the program to the target board.

  4. Launch the debugger in your IDE to begin running the demo. Please insert the SDCARD into card slot(J32)

Running the demo

When the demo runs successfully, the log would be seen on the terminal like:

MMCCARD polling example.
