STM32F746G-DISCO internal RTC not working

[Ameya M]

Hello,

I am using STM32F746G-DISCO board for internal RTC. And using Keil u5 IDE

I enabled the Internal RTC clock in CubeMX, set the time and date.

And am using HAL_RTC_GetTime - API in while loop for reading sTime and sDate.

I am monitoring sTime and sDate on STMStudio.

But none of the (seconds, minutes, etc..) update. They remain same.

Thank You,
