• The ROM API supports native support for callable crypto functions in the user application.

Hardware requirements

• Micro USB cable

• RD-RW61X-BGA board

• Personal Computer

Board settings

No special settings are required.

Prepare the Demo

1. Connect a micro USB cable between the PC host and the MCU-Link USB port (J7) on the board

2. Open a serial terminal with the following settings:

   • 115200 baud rate

   • 8 data bits

   • No parity

   • One stop bit

   • No flow control

3. Download the program to the target board.

4. Launch the debugger in your IDE to begin running the demo.
