Actual message is host <ip address> is not alive
Then please write EXACTLY this the next time you report a problem.
I have done of the obvious and non-obvious checks. e.g. ethernet
cable and stuff outside the box is fully operational. Infect I see arp packet going out on ethereal. I know that reply is sent by the pinged box.
How do you know that? Did you see the packet on the wire?
Did you see how it entered the Rx code in U-boot?
Do you also see the ICMP packet sent by U-Boot on the wire?
No
Did you trace that the Tx code was actually executed?
My hardware guy has checked all the clocks and he assures me that
they are all in order. He also made external loopback, i.e. ethernet cable with input going to output, this also works.
How did you test this that you know it works?
Well, initially, when I was getting TX timeout, I stop getting timeout message with lopback cable.
Arghh... And what exactly do you know from this test?
