Prepare the Demo

  1. Connect a mini USB cable between the PC host and the OpenSDA USB port on the board.

  2. Open a serial terminal on PC for OpenSDA serial device with these settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Reset the SoC and run the project.

Running the demo

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