Hi Yacob,

This looks like a MAC layer configuration problem of STM32F4, and has little to do with LWIP. First step would be to check configurations and DMA operations, You could also try to use internal loopback option of MAC

Hello all,


My board contains the controller of STM32F4 and Ethernet Phy of Microchip.


The board is connected to PC by Ethernet LAN.


The receive path of MAC is connected to Scope.


I send ping from PC and see on Scope the packet to MAC of the controller but there is no interrupt.


Can somebody advise?
