Sorry , i'm not good at English
I have made my own board DUE + W5500 , I also used the official schematic as a reference to design it,
When programming a sketch as a chatServer i can get my local ip pretty well , but when I plug a cable into the RJ45 connector , w5500's light won't be on (DUPLED,LINKLED,ACTLED), and it can't be ping on cmd,
if there's any information that u think is helpful please tell me
and my MISO signal is not clean will that cause problem either ?
thanks all
frank.
