Do i Have to add uenv.txt too ?

Please Give the suggestion.

how did you prepare you SD card? Definitely
it does not contain what u-boot expects

I have now executed ./create-sd-card.sh
and after that i have laoded new boot file from
/boardsupport/prebuild-image
and rootfs
i ghave loaded from
/target-NFS

Now I have tried to load the sd card
my beagle is working fine !!!

Thank you
