Hi ynezz,
I load my kernel via TFTP. Did you replace your redboot as
well, i can't load the zImage produced by OE, i get an Unrecognized
image type: 0xe1a00000 error.
for my boot i was using this for the command
load -b 0x00218000 vmlinux
exec -c "console=ttyAM0,115200 ip=192.168.0.50
nfsroot=192.168.0.1:/rootfs"
i've attached the boot output
Thanks
Anish

how do you load your kernel via NFS? I think, that it's
not possible at all.
How I do it in redboot (for testing I load the kernel via
HTTP)
In redboot on ts72xx I've this
load -v -r -b 0x00218000 -m http -h 192.168.1.90
/~ynezz/zImage-2.6.36-r2-ts72xx.bin
exec -c "console=ttyAM0,115200 ip=192.168.1.10
root=/dev/nfs
nfsroot=192.168.1.90:/home/ynezz/data/devel/oe/ts72xx.git/tmp/deploy/glibc/images/ts72xx/rootfs"
192.168.1.90 is IP of my notebook/server. Hope it helps.
