Prepare the Demo

Connect a mini USB cable between the PC host and the OpenSDA USB port on the board.
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
Download the program to the target board.
Reset the SoC and run the project.
