I have a problem with STM32F415RG....

 

My project has two system of wakeup from standby, first is PA0 pin and other RTC Alarm.

 

If i put a single way of wakeup, like only PA0 wakeup work, if i put only RTC ALARM wakeup work, when i put both, not work...

 

I make many test:

 

When i put a alarm 30 seconds after standby, and i move the PA0 pin before the ALARM start, wakeup from pin work 

When i put a alarm 30 seconds after standby and i wait the RTC ALARM, the system not start and not start anymore also from PA0 pin

 

Someone has same problem ?

 

Sorry for my english
