Hi,

 I did a basic udp echo server  EWARM project using the cubeMx for NUCLEO-F767. The problem is that sometimes it is need to send a couple of udp packets to receive them and another problem is that if I enable the caches, the board don't receive packets anymore.Can someone send me a simple EWARM udp-ip example to validate my NUCLEO-F767 hardware and use it as reference to discovery what is wrong with my project?Ari.

Hi,

I suggest to you this example within 

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef7.html

:STM32Cube_FW_F7_V1.4.0\Projects\STM32756G_EVAL\Applications\LwIP\LwIP_UDP_Echo_ServerYou can get inspiration from this example and compare with your generated code to identify what is going wrong.Regards

I already used the file udp_echoserver.c from this example in my project generated by the cubeMx. Or the generated cubemx code is bug or it is my hardware.

I do not understand how the ST launches a card that has only ethernet, without any ethernet examples.

I am also suffering with this board. I spent three days trying to diagnose why the board stops receiving packets and just counts up crc reception errors at startup. Maybe ethernet on this board is just buggy and that is why no samples are distributed. I posted a topic about ethernet not starting reliably, hopefully someone has the answer.
