STM32F446RE stand by mode and wake up with RTC alarm

Hello All,

 

I am trying to put my MCU into stand by mode and then wake him up with RTC alarm. I am pretty sure that this part is working for me. My problem is that when the MCU wakes up it doesn't continue to execute the code from the line bellow  HAL_PWR_EnterSTANDBYMode() , it seems like it's starting to execute the code from the start of the main function and then it doesn't execute all the code, it's just executes few lines and seems like it's getting stuck in a loop.

 

Any ideas on what am i doing wrong ?

 

Thanks !!
