Hi everyone,

I have working software on FRDM K64 and I tried make own hardware - I inspired from FRDM K64 schematic. Now, I have issue with connection ethernet. Schematic is on attachment. 


I tried read registers from KSZ8081RNACA - it is OK. When I connected cable, then it is not see any change. Any change on registers, any change on router. 


Please, could you help me, how can I debug it and find issue?


Thank you
