STM32H743 Ethernet issue

Got a problem with ethernet on my custom board with STM32H743BIT and DP83848 PHY

everything 'seems' to work, but I see no outgoing traffic from my board on wireshark.

Rx working though, screenshots attached.

I read an article

https://community.st.com/s/article/FAQ-Ethernet-not-working-on-STM32H7x3

but it didnt help.

Some clues anybody?0693W00000WJZBtQAP.png0693W00000WJZBoQAP.png

Hello @AlexSmart​,

Did you try the latest release of STM32CubeH7 (version 1.11.0)?

Please check this post: How to make Ethernet and lwIP working on STM32, it may help you as contains the most Ethernet issues that are already fixed or follow-up action is ongoing.

If just the Tx is not working, it could be this issue:

Or anything from my other topic, to which Imen gave the link already...

Well, it might be it. I switched to Oryx Cyclone stack and it works perfectly
