Question

Flash status register CFGBSY bit is always set on init

Hi.

I can see that CFGBSY bit is set and reset in some MX peripheral init functions, but the main problem is that it stays set after MX_TIM1_Init and it locks my flash for any operation.

Did anybody saw this kind of problem?

Any help will be appreciated.

Thanks.

I think I have found the problem. It doesn't happens because of any peripheral or cube initialization, it happens when CPU2 get into hard fault.
