HAL_Delay hangs up in infinite loop

Hi,

I'm trying to port ble sensor demo to System workbench on nucleo F411RE.

Everything now compile fines but nothing happens when executing.

Step by step execution shows that HAL_Delay causes an unhandled exception and I

definitly don't understand why.

I don't know if it helps but a first call to HAL_Delay performs ok. The second one doesn't.

It's my first time with stm32 so any idea is welcome.

Thanks

Julien

Ok, found that an interruption routine was not implementing causing

an error then jump to the last irq of a switch case which is wwdg even.
