I have a AM3517 EVM and am following the Linux User Guide Software Documentation by Logic PD. I got stuck attempting to boot from NFS (see section 4.4)
I am new to Linux, so my problem could be on my Ubuntu 11.04 PC side of network too.
Here is the last part of the boot output:
eth0: attached PHY driver [Generic PHY] (mii_bus:phy_addr=ffffffff:00, id=7c0f1)
Sending DHCP requests .
PHY: ffffffff:00 - Link is Up - 100/Full
., OK
IP-Config: Got DHCP answer from 192.168.0.1, my address is 192.168.0.163

And this is where it hangs - I believe it has something to do with where and how the rootfs is setup on the PC, but I am not sure how to correct the problem.
The AM3517 EVM printenv is:

Can anyone see what I have wrong? Is there any other information which would be helpful to check?
Thank You
