STM32F415RG exit from standby without reasons

Question asked by marco on May 9, 2018



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
