STM32F746-Discovery Ethernet No frames/pings Received

Hello STM community,


I am trying to implement Ethernet communication to PC from STM32F746 discovery board. In doing so I have used STMcubeMX for the driver generation and also seeking some help from examples given by st repository version 1.7.0.


Now, When I am running example of 'LwIP_HTTP_Server_Netconn_RTOS', Everythings seems normal. It works as described.

Going further in the custom project, I have added Lwip middleware, Ethernet RMII mode and some standard peripherals such as LCD and SDRAM (as given in the board selection/initialization). Also I am using static Ip address and would use udp for data transfer.


When I try to debug the custom project that I can see that it sends the gratituous ARP on network and if I hard code it to send multiple ARP request that still it's capable to do so. However, there is no frames received. In receive part, no functions are called such as low_level_input or  ethernet_input.


Could anyone suggest me where should I start troubleshoot to solve the problem?


I appreciate your effort deeply for consideration.
