Change Jumper J31 from 1-2 to 2-3, Jumper J35 from 1-2 to 2-3. LPI2C one board:

Transfer data from MASTER_BOARD to SLAVE_BOARD of LPI2C interface, LPI2C3 pins of MASTER_BOARD are connected with LPI2C3 pins of SLAVE_BOARD

MASTER_BOARD        CONNECTS TO         SLAVE_BOARD
Pin Name     Board Location     Pin Name     Board Location
LPI2C3_SCL   J51-12              LPI2C3_SCL    J51-12
LPI2C3_SDA   J51-10              LPI2C3_SDA    J51-10

Prepare the Demo
===============
1.  Connect a micro 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.  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.
