Hello friends,

I was originally using STM32F207, FreeRTOS,  LWIP ,ENC28J60 , system works fine.

Because I need more RAM, I migrated to STM32F427, but unfortunately network no longer works now, ARP seems working but Ping fail (Request timeout)

    Hello

    Lang.Kevin

    ,

    You may check with a LwIPexample under STM32CubeF4 with a similar type of your projectto deduce what is going wrong in your case.

    The workingexample available at this path can help you as an implementation example: STM32Cube_FW_F4_V1.0\Projects\STM324xG_EVAL\Applications\LwIP
