WWDG interrupt

[Phang]

Hi, 

After configured the GPIO pins via STM32CudeMX and generated the code, when I run the firmware, the "WWDG_IRQHhandler()" problem keep appearing from no way and hinder me from the rest of the development. Please see the attached screen shoot picture. Even after I commented out the customize codes the problem didn't go away. Same problem seen on the P-NUCLEO-DONGLE too. I configured the MCU to support "USB HID + Zigbee".   

Any help?

This is probably the default IRQ handler, which means you've enabled an interrupt that you haven't implemented in the code. Perhaps it's misspelled.

Look at VECTACTIVE bits in SCB to find out which interrupt it's actually in.
