Hardware requirements

  • Mini/micro USB cable

  • MIMXRT700-EVK board

  • Personal computer

Board settings

  1. Example running at 325MHz which need PMIC power supply.

  2. PMIC is required to drive 1.1V on VDD2, then JP1 and JP3 on the RT700 EVK need to be shorted for proper operation

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.

Run the Demo

The log below shows the output of the demo in the terminal window (compiled with ARM GCC):
