Stm32F756 Nucleo Ethernet/Lwip problem

[Okaan]

Greetings , I ve tried to work with ethernet and lwip on stm32f756 nucleo board but somehow didint figure out whats wrong. 
https://community.st.com/t5/stm32-mcus-products/stm32f756-ethernet-and-lwip-lwip-ram-heap-pointer/m-p/768279#M272145
I tried this solution 
Watched https://www.youtube.com/watch?v=Wg3edgNUsTk&list=PLfIJKC1ud8ggZKVtytWAlOS63vifF5iJC&t=607s
but still cannot ping my board with direct connection on my computer or by using my internet modem.
May I get example or proper tutorial for that step by step because I didint understand whats going on , why I need to change ram locations etc.
I just cancelled everything and uploading my file here. May I get help for eth?

Hello @Okaan,

First of all, welcome to ST community!

Second, your project is missing some key configurations such as MPU and the implementation of the UDP echo server in itself Without it, the board can't process the pings you are sending from your computer. 

I suggest you try the LwIP_UDP_Echo_Server example found on STMicroelectronics' Github repository; it will help you get an in-depth look on the implementation of such application and from it you can adapt it to your project.

Best regards,
