NUCLEO-F767ZI Ethernet can't reply ping without FreeRTOS - unreachable

[emirhan37]

Hi, I am trying to develop ethernet project on stm32f767zi. I am facing the problem when I am trying to pinging from PC to stm32. "Destination host unreachable." How can I fix this? I read similar topic but anything couldn't solve the problem. I shared the configurations and main code with you. I am waiting for the answers. They will really help me I believe. 

Have a nice day.

So is the STM32 actually on network that should be reachable from the PC?

So what debugging have you done?
Have you used Wireshark or similar to see what's going on?

This is the log when I try to ping from pc to stm32. 

I tried to ping from pc to raspberry pi with same cable and same target ip and it was successfully done. I need to see ping communication between pc and stm32f767zi over ethernet.

Hello @emirhan37 ,

Could you try this example I have shared you will need to change the IP address accordingly in lwip.c file.

Hi, You project is worked! Thank you so much. Can you describe the changes or differences with my code. What is the problem in my configurations?

Hello @emirhan37 ,

I didn't go throw you configuration enough, so I recommend you compare the two projects to see the difference with a tool like winmerge.
