Does NUCLEO-H755ZI-Q Support Ethernet?

[Deepa_599]

Hi everyone,

I'm using the NUCLEO-H755ZI-Q board and I’m a bit confused about its Ethernet support.

The user manual (MB1363 Rev C) shows that both H745ZI-Q and H755ZI-Q support Ethernet using the LAN8742A PHY. It also lists jumpers and solder bridge settings for enabling RMII.

But when I checked my H755ZI-Q board, it looks like the PHY chip and RJ45 connector are not soldered. So now I’m not sure:

1. Does the H755ZI-Q actually support Ethernet out of the box?

2. Or is Ethernet only available on the H745ZI-Q version?

Would appreciate any help or clarification. Thanks!

Hi,

This is interesting, I am using H755ZI-Q as well and Ethernet works out of the box for me.

The user manuals might be a bit confusing since they cover multiple board versions. Have you tried testing a standard Ethernet example from CubeIDE just to confirm whether it is working or not for you?

Yes, it supports ethernet.

Show a picture please. If parts aren't soldered, they would fall off of the board.

Thank you for your response!

I haven't had a chance to test it yet, but I appreciate the clarification. I’ll try it out soon and get back with any results or further questions if needed.

None of this makes sense. How do you expect the examples to work if you claim you don't have the PHY chip and connector on the board? Is this a brand new Nucleo or did you grab this board from a junk bin? Show a picture of your board.
