I can't access any PCs within the LAN, although the eth0 seems OK
 

My cortex-a8 running kernel 2.6.37. I just compile with networking support for it. And now, the eth0 device looks like works OK, but it can't access any others with the LAN.
When I plugin the net cable, I can see the message like: "PHY: 0:00 - Link is Up - 100/Full"
here is the output of ifconfig:
eth0 Link encap:Ethernet HWaddr *****

So, where the issue should be? or how to check it?
Thanks all.

Are you running thru a router? What is the IP of your other devices?

Also, by not connect, are you trying to ssh into them or you can't even ping the other devices?

Lastly, what does your /etc/network/interfaces file look like?

Thanks for your help.
I checked the booting documents, and found some pins where shared between flash and Ethernet.
The issue resolved via bypassing the initialization of the flash.
