Differences between the Nucleo-144 STM32H743ZI2 and STM32H743ZI

[J.Bepler]

I'm stuck trying to understand the differences between the two Nucleo-144 boards

STM32H743ZI (seems to be the older version but with lots of resources but outdated)

and

STM32H743ZI2 (current version but i can hardly find working examples and resources)

can someone point me in the right direction?

why do some examples designed for the ZI not work on the ZI2 ?

where exactly are the diferences, at first glance they seem identical.

Handful of pins related to LEDs, QSPI and ETHERNET, as I recall, reducing/removing some potential stubs. Solder Bridges and default usage expectations.

could you go ito detail about the ethernet pins particularly? where did you find documentation that explains that?

Please check DB3171 for more details.

You can also check the user manual UM2407 and board reference MB1364

I went through the manual and schematic whilst porting some QSPI support.

Perhaps start by looking at the MORPHO​ connector.
