As previously…. I’m not much of a Software/Firmware type, I lean Hardware…so I think I’m at a point short of tearing into my own tric….to do pin to pin continuity checks.
You seem to be the software/ firmware type imo. The risk of bricking is possible. You already have the Fcopy.
Why not try the engineering STM32H750VBT6 development board?
They are cheap and different ones if you search.
Here’s an example and what it features and comes with…some even with a display mounted.
