Hardware requirements

  • Mini/micro USB cable

  • MIMXRT1060-EVKB board

  • Personal Computer

Board settings

The board enable QSPI flash (U33) by default. To enables hyper flash (U19), some hardware rework is needed: Mount R403,R398,R401,R407,R408,R409,R412 and DNP R402,R405,R406,R410,R411,R413.

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. Download the program to the target board.

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

Running the demo

When the example runs successfully, you can see the similar information from the terminal as below.
