Board settings

Remove the resistor R347,R348,R349,R351,R363,R364,R365. Weld 0Ω resistor to R346,R350,R356,R362.

SPI one board: Transfer data from one board instance to another board’s instance. SPI0 pins are connected with SPI0 pins of another board

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:
