Hi,

please find the attached register values of WWDG register on Reset position

This can be a common handler for all interrupts for which you haven't written a handler, so it can be a hardfault too.

Check pending NVIC registers for candidates.

Check spelling for Handler, watch .CPP naming issues.​

Hi DeLorean,

Thanks for your reply.

Checked NVIC registers status, but there is no pending interrupt, please find the attached values for your information.

Is there any thing need's to check apart from Handler spelling and NVIC

VECTACTIVE bits will show what the currently active interrupt. Probably it isn't WWDG.

>>but there is no pending interrupt,

Non-zero ISPR/ICPR suggests otherwise..

I'd need to know the specific part to try and unpack that. Keil has an NVIC view breaking the content down by IRQ name from .SVD file
