HI, 

i have a project for stm32f415rgt, i generated the code with mxcube (last version) but i have a strange behaviour.

I setted the ALARM_A + ALARM_B + Tamper + PA0PIN to exit from stnadby, but every 3300 seconds, the micro start without reasons.

I put a microsd to save the RTC registers at wakeup, but no flags are setted on registers.

Which cause can wakeup the micro from standby ?

Some register can capture the event of wakeup ?

Some idea ?

Sorry for my english
