Hi@Akhil1

Sorry, that's all we have, you can port it to new RTD version by yourself.

Hi@Akhil1

The demo in the linker which i provided to you is working or not?

There is no big difference in RTD 2.0.0 vs RTD 3.0.0, It must a problem that something wrong with your porting.

Hi@Akhil1

test RTC is working as expected or not,

If yes, check is RTC have set as wake up source or not.

Hi@Akhil1

use debuger tool to see the RTC interrupt or other behavior is expected or not.
