Ethernet problem on STM32H747I-DISCO board

[magianf]

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.

hii @magianf  could you share your configurations settings.

thanks for the reply @jumman_JHINGA, this is my .ioc made with IDE version 1.18.1

if you need other files just ask me.

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

Hi all,
is there anyone using NetXDuo on the STM32H747 micro that can help me with the CORTEX_M7 MPU configuration settings.

 

thanks a lot
