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.

Note: To debug in qspiflash, following steps are needed:

  1. Select the flash target and compile.

  2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.

  3. Start debugging in IDE.

    • Keil: Click “Download (F8)” to program the image to qspiflash first then clicking “Start/Stop Debug Session (Ctrl+F5)” to start debugging.
