Configured WWDG timer in CM7 core of stm32h747I-disco and i have taken a window period of 10msec to 50 msec and configured according to that in cubeMX. also enabled Early Wake up interrupt and Window watchdog interrupt.
i am trying to check interrupt call back WWDG_IRQHandler() before reset as per reference manual rm0399.
issue: Core Reset is happening properly but WWDG_IRQHandler() is not getting called before reset
