Hi Naveen,


This is nxp community. So I think you should ask this question in raspberry community (for better support). BTW you can also get the assistance here if you will elaborate your question (like which RTC module are you using  and if it is on the I2C so you can check the i2c communication through i2c utility) in a precise way.

Thanks,

Vinod
