I am a newbie to u-boot and embedded linux. I am trying to build a development environment around a Freescale P4080DS board. Presently, I want the target to boot from a kernel image in flash and to mount an NFS root filesystem. This is not working.
Please restrict your line length to some 70 charatcers or so.
Also carefully check where you are posting to.
This is the U-Boot mailing list, and your problems appears not to be related to U-Boot. You should post Linux related issues on a Linux mailing list.
bootargs=console=ttyS0,115200 root=/dev/nfs rw ip=172.29.68.13 nfsroot=172.29.68.252:<my file system path>
Please read the Linux kernel documentation for correct setup of boot arguments for Linux.
Firstly, I have not installed an NFS server on the host. Well, I should be able to do that.
Off topic here.

Off topic here.
Why is the ip address shown as 192.168.1.100 but I set it as 172.29.68.13 in bootargs?
I guess your kernel determined the IP address using DHCP. You did not tell him not to do - for that, the "ip=" parameter needs more components, especially a trailing ":off" part.
