Hi,
I have interfaced micrel ksz8081 with am335x in RMII mode with externel 50MHZ clock. Able to bring up the link but communication is failing, DHCP fails in booting. If I set static IP and ping, I can observe ARP messages on Wireshark, Probed Rx lines on oscilloscope, able to see communication on RXD0 & RXD1, MAC is failing to process the RX messages to the upper layer. Please guide me how to fix this issue.
Thanks & Regards,
Dileep
