I want know if is possible to wakeup the MCU(STM32F4) from standby power mode with only the Wakeup pin, without setting the RTC allarm.

i have try this but the MCU don't wakeup.
 

HAL_EnableDBGStandbyMode();

HAL_PWR_DisableWakeUpPin( PWR_WAKEUP_PIN1 );
                          
__HAL_PWR_CLEAR_FLAG(PWR_FLAG_WU);
                    
/* Enable WKUP pin */
HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN1);
 
/* Request to enter STANDBY mode (Wake Up flag is cleared in HAL_PWR_EnterSTANDBYMode function) */
HAL_PWR_EnterSTANDBYMode();

if i use the ST example code with wakeup from Pin or RTC allarm the mcu wakeup correctly, so i don't think there are hardware problem.
