NUCLEO STRM32H743 - Ethernet running now - after fixing hardware problem...

This is not a question then an information for NUCLEO STM32H7 (or others...) users:

After searching so many hours inside the software today i found the reason for malfunction:

Jumpers JP6 & JP7 was well closed (optical impression), but gave no stable connection.

After replacing the header plugs by soldering, the problem is gone, i'm happy.

By the way: Have checked even before signals with the scope and signals was seen -

anyway they was not stable obviously.

So, my suggestion is closing this jumpers in a save way and then trying to understand the

complex sofware :)

Michael.
