Hi @Prerana_Diwani ,
Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.
Please tell me which SDK version and demo you are testing now, please tell me your used SDK demo path, then I can help you to check the details.
For the synchronization with RTC, maybe the demo didn't add it, but if you need it, you can add the RTC code by yourself to sync it.
Wish it helps you!
Best Regards,
Kerry
