Hi,I am using the STM32L082 and looking for ways to have a watchdog implemented.However during long periods of low power sleeps (e.g. 12 hours) I would like to freeze the IWDG downcounter.Is this possible for the STM32L082? Thanks
STM32H745 IWDG if it reaches downcounter 0x0000, it mentions that system reset is generated.Is there any way to reset only M7 just or M4 just core.Also Errata Mentions that AXI domain is locked when watchdog reset is limited to CPU1 or CPU2 only. Is...
After enabling independent watchdog(IWDG) and write access, I am setting prescaler and reload counter and then waiting for IWDG_SR register to be 0x00000000. Waiting period is taking approx 48 milliseconds, but as per datasheet it should take five RC...
STM32L562I have the IWDG set up to fire 4 seconds if no HAL_IWDG_Refresh(&hiwdg) is executed.Very occasionally, a lockup condition occurs.But the STM32 does not reset.Moreover, grounding the nRST pin does not reset the STM32Scoping the nRST pin, i ca...
Hello.I am running STM32L412 microcontroller in low power GSM design. All works great, but I would also want to add watchdog just in case.I am in STOP2 mode most of the time, and I am waiting for interrupts from GSM module or MEMS IRQI configured IW...
Can you confirm that the formula on the RM0454 manual to calculate the wwdg timeout is wrong? Shouldn't the WDGTB[1:0] parameter be WDGTB[2:0]?Thank you
Here is my code for IWDGLL_IWDG_EnableWriteAccess(IWDG); // Set the prescaler value of 8 to the IWDG LL_IWDG_SetPrescaler(IWDG, LL_IWDG_PRESCALER_8); // Specify the IWDG down-counter reload value LL_IWDG_SetReloadCounter(IWDG, 2000); ...
