    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
    IP-Config: Complete:
    device=eth0, addr=192.168.0.163, mask=255.255.255.0, gw=192.168.0.1,
    host=192.168.0.163, domain=internal, nis-domain=(none),
    bootserver=192.168.0.1, rootserver=192.168.0.150, rootpath=

    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
