Overcurrent Issue on Nucleo-H753ZI

[aookes]

Could you please help me with my Nucleo-H753ZI board power issue? I would greatly appreciate your assistance.

Earlier, the nucleo-h753zi board worked normally when I applied external power from a power supply at 9 volts.

When I applied power using a 9-volt battery, overcurrent occurred and the U12 component overheated. Could you please advise me on how to handle this situation?

Other than the power supply, nothing else was connected - only GND and the external power supply pin were connected. Even without external power, when I connect USB, the overcurrent LED still comes on.

I would be very grateful for your guidance on resolving this issue.

I think the board has probably crossed the point of no return.

Can you be more specific about how/where specifically you are applying external power? Have you changed any jumper settings? A picture of the setup may help.
