Hi,
First post, and also a U-Boot newbie.
I'm working with a U-Boot configuration that I did not build myself. I'm having
trouble getting U-Boot to mount an NFS root file system on my target platform.
I have read the U-Boot manual regarding setting up 'bootargs' with all the
necessary NFS information, but Linux is ignoring the information and mounting
the resident file system that's on my target; which of course I'm trying to
bypass.
>From printenv:
bootargs=console=ttyS0,115200 root=/dev/nfs rw
nfsroot=10.10.1.16:/home/heyendal/buildroot/buildroot-2009.08/project_build_arm/ILS_CM/root
ip=10.10.1.8:10.10.1.16:10.10.1.1:255.255.252.0:cm_carlh::off
Below is the output that I get that clearly shows the correct NFS information
is getting passed to Linux, however the subsequent messages after the freeing
of memory is from my resident file system:
NET: Registered protocol family 17
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
IP-Config: Complete:

host=cm_carlh, domain=, nis-domain=(none),
bootserver=10.10.1.16, rootserver=10.10.1.16, rootpath=

In the U-Boot Manual section describing how to mount an NFS file system, the
example they use shows Linux mounting an NFS root file system, which is more
like what I'm expecting.

Can someone help with my problem?
