Do not working ethernet with kinetis K64 with KSZ8081RNACA

zavovi

Hi everyone,

I have working software on FRDM Kinetis 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? Any idea?

 

Thank you

Vilem
