Thanks scott. There was an issue with the file system. Now my board is up with the linux boot prompt . But ping is not working. The local loopback ping works. My phy chip BCM5221 is connected on port A I am using FCC1 as the MAC. I see that the intrrupt handler is being registered properly. And even the fs_enet_start_xmit() gets called and it returns with return NETDEV_TX_OK. When I do a ifconfig -a I see the TX packets count increases for the loop back device but not for eth0. I am using the wireshark tool to see any packets on the witr. But don't see any ARP packets coming out on the wire. Can you please suggest . Below are the logs. Attache dis the .dts file. I have commented the bcsr register part in the .dts is this required.
