STM32H7 - How to tell if debugger is attached?

[n2wx]

So I was handed code that breaks when debugging, but to fix the breakage breaks a power control on the board. Rev A only has this problem but Rev A is what I'm stuck with . Nice, right?

So I need a way to tell at run time whether the debugger is attached.

Does anyone have any idea how to accomplish this without changing the hardware?

So all this time you're practicing the Murphy Law...

Murphy had a better time than me. When it breaks I change it and usually wind up doing the wrong thing. Don't ask me about my ham rig which keeps breaking down in interesting and creative ways. That worked great until I plugged a (supported) 4 ohm speaker in and now the audio is all screwed up.
