LWIP sends an arp request for himself

Hello,

I am trying to set up  a UPD communication with a nucleo-H755ZI-Q board.

Now I have the effect, that the lwip stack sends out an arp request for its own IP address.

I double-checked the IP address and destination address to make sure they were correct.

 

Does anyone have any idea, what could be causing this?

Thank you.

HiSt

Hello @HiSt, and welcome to ST community!

Could you please provide more details, such as a screen capture of the Wireshark-captured frame and the CubeMX configuration for LwIP? The more information you provide, the less time it will take to find a solution.

Best regards,
