Hi. I am working on a design that uses a W5500 for networking. I followed a reference schematic and believe all my connections are correct, however our customer is facing issues with the network connectivity. Basically, the device thinks that the link is always on. The Link LED turns to yellow about 1s after booting and stays on, even if I plug in an ethernet cable from a router.
Does anyone know why this is happening? I have followed the reference schematic. The only thing I can think of is that maybe our pinout for the RJ45 is wrong? Anyone have any idea? We are using HY931147C from HANRUN.
I would appreciate any help please.
