Hi everyone,
I have a problem with the Ethernet connection that I can't solve on the STM32H747I-DISCO board.
I followed Adam Berlinger's guide step by step (https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308) and the Ethernet works for a while, but when I send messages on udp or start the ping, after a while it stops working.
can someone help me?, I've been trying to fix this problem for two months now but without success.
thank you very much in advance.

Hi @magianf,
Apologies, but I'm currently unable to open your .ioc file as it was created using STM32CubeMX version 6.14.1, while I am using 6.14.0.
In my experience, after upgrading to 6.14.1, the Ethernet functionality stopped working in my project. I tried multiple settings but couldn’t resolve the issue. Eventually, I downgraded CubeMX back to 6.14.0, and with the same configuration, Ethernet started working again.
Based on this, I would recommend trying with version 6.14.0 to see if that resolves the issue on your end as well.

thanks for the reply, I'm trying to use NetXDuo, but I can't find a good example to map the H7 memories
