On a whim I bought a Nucleo-F767ZI, which has a built-in ethernet connector (not Wifi). I found that setting up LwIP was a fairly involved process, thus I made notes which are included in the attached file. I am assuming the reader, like myself, is new to the CubeMX and Eclipse environments and will find these useful. To avoid complexities, I have not made use of RTOS.
Please feel free to share these.
