Why there is yellow triangle before RCC

I am trying to setup stm32h745 Nucleo board.

Is the yellow triangle issue of concern or not ?

I am using internal oscillator.

A yellow triangle means some features of that cannot be enabled due to your current settings, but it doesn't mean there's an error. It is confusing.

In this case, it means you can't enable Master Clock Output 1 because that pin is being used elsewhere. That's it.

It's not a problem that you need to fix.
