Got the board partially working.It turned out that incorrect clock was supplied to GTX_CLK .

The problem i am running into right now is as follows:

- I am able to ping the board about 10-15 minutes past initialization.At that period of time,I am able to ping most of the packets correctly.The ping requests which are timed out are ICMP replies which are corrupt (failed checksum) ( I am able to see that in Wireshark).

-After that time is passed (10-15 minutes),I am receiving ping requests ,but the board does not reply (Probable cause is that the frame ,which includes ethernet,ip and icmp , that is received is corrupted,as I can see on debug that icmp_input () callback function is not entered).

What could be the problem and how can It be solved?

Thank You.
