well I haven’t given up quite yet. after reading through the forum I found this thread: High temperature and high consumption
the state of the ACT LED isn’t mentioned but the W5500 was getting in to a funky state. I have modified teh WIZ850io to remove the ferrite bead between AGND and DGND and changed the damping resistors to 0 ohms. Now we haven’t been able to get the W5500 stuck in the funky state with the ACT LED on constantly. I am not going to call this fixed yet. We are going to stress the unit for a few days and see what happens.
If this works we will just add the W5500 to our boards instead of the WIZ850io and a way to power cycle the device from the micro. Fingers crossed.
