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.
