console=ttyAM0,115200 ip=dhcp noinitrd root=/dev/nfs init=/sbin/init
nfsroot=192.168.0.1:/proj/tools/buildroot-2009.08/project_build_arm/uclibc/root/
This is my argument list to the kernel.

This was my last message from the kernel

VFS: Mounted root (nfs filesystem).

Freeing init memory: 120K

Based on Francisco's private email, I made some nodes in the /dev
directory as by default, buildroot creates only files and not device
files with major/minor numbers.  I made the nodes by copying some of the
devices from the board's default disk while it was running.  Now, when I
boot, I get the following repeating sequence.

can't open /dev/~: No such file or directory

can't open /dev/tty1: No such file or directory

can't open /dev/tty2: No such file or directory


Looks like the culprit, is the improper device setup.

This is not set.

I will give this a shot later on today.

Thanks.
