[U-Boot] Not able to boot from USB in u-boot-2011.03 version

[sadashiva reddy]

Hi Sir,

       I am able to access the USB keyboard and also it shows 1
storage device found. U-boot is able perform all USB related
operations except reading operation. In u-boot I am not able to boot
from USB. I am using u-boot-2011.03 source code.

When u-boot comes up I am seeing the version on hyper terminal is
u-boot-1.1.4 year is 2005 . In this image I am able to boot from USB
but facing problem on tftpboot. But if I use u-boot.2011.03 image I am
facing same problem booting from USB.

 If I use usbbo 400000 0:1

       I am getting unknown image format ot type.

If i use fatload usb 0:1 400000 vxWorks.img
   It shows reading and I am also getting the bytes read as the size
of image size. But later it restarts the board.

How can I get the solution for and which is the proper u-boot version
where all drivers are working properly.

Thanks in advance.

Best Regards,
Sadashiva.
