Hello all, i am a beginner with stm32f7 and i would like to be sure than there is not other solution than the wake up from standby mode resets the mcu ? Thanks,

Let's try not putting entire question into title/summary.

S​TANDBY turns off the core, it comes out of reset when it turns on again, use a different sleep mode if you want/expect different behaviour.
