my ethernet hardware based on W5100 is not working. I have suspicions regarding soldering issues.
However I have one more concern which I would like to ask you…
I power all W5100 pins with 3.3 volt. ONLY reset pin is managed with 5volt source.
Can you please inform me if RESET PIN can manage 5volt or not?
Acc. to datasheet there is no information regarding reset pin voltage tolerance.
