NUCLEO-H743ZI2 documentation

Hello everyone!

I'm new to the NUCLEO-H743ZI2 board. I need help with two questions:

1) I can't find a description of the STLK backup port -CN2 anywhere. Can you tell me if I can use it to program other STM32 devices on other boards, and how?

2) Can anyone share the schematic for the H743ZI2 board?

The presence of the CN2 connector on the board also bothered me—it's supposedly there, so why is it there?

Already answered here.

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
