Overview

The SNVS LP SRTC project is a simple demonstration program of the SDK SNVS LP driver. The test will set up secure RTC (SRTC) date and time to a predefined value and starts the counter, then the SRTC counter value is synchronized with non secure RTC (RTC). RTC then triggers an alarm after a user specified time period. The alarm will be set with reference to this predefined date and time.

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA USB port on the target 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. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

The log below shows the output of snvs example in the terminal window:
