U-Boot ignores uEnv.txt

Hello All,

I took latest U-Boot and created my own uEnv.txt so that it mounts RFS from NFS.
But is seems that it ignores uEnv.txt.

When I load the uEnv.txt manually as below:

load mmc 0:1 0x80800000 uEnv.txt
env import -t 0x80800000 459

then it works.

If I let u-boot run then below is the output
