WWDG RESET Due to osDelay

Behaviour of WWDG on STM32L071KZUx.We are trying to read and write 256bytes from the Slave. In a specific case the Slave needs delay of 120ms to process the data when we add 120ms of delay in the MCU, the void HAL_WWDG_EarlyWakeupCallback(WWDG_Handle...

I am using a STM32G474 and testing it in a nucleo-64 board. When I enable the hardware window watchdog and the hardware independent watchdog my software does not run. it seems to get stuck after each startUp.

The hardware watchdogs is set through an option byte modification done by software and right afterwards the WWDG and IWDG init functions are called as well as the refresh API, called periodically. If I change my code to use the SW WWDG and IWDG then ...

Timing issue when TIM10 interrupts HAL IWDG macro

I am using a STM32F746VET6 to drive time critical signals on up to 14 pins. I am bit banging these signals in the ISR. I was surprised to find after a benign change I started to have jitter in these signals. I tracked it down to the ISR firing during...

STM32U5 sometimes does not reconfigure IWDG.

At startup, I set the watchdog timer to 8 seconds.IWDG->KR = IWDG_KEY_ENABLE; IWDG->KR = IWDG_KEY_WRITE_ACCESS_ENABLE; IWDG->PR = IWDG_PRESCALER_64; // 8 s IWDG->KR = IWDG_KEY_WRITE_ACCESS_DISABLE;Further, in the interrupt, when the button is pressed...
