I have put down the entire sequence. I have also shown the
u-boot parameters.

Could anybody please tell me why the board stops after the command. I have
the same file system flashed on my NAND flash and if i show that path for
the boot operation every thing works fine. (i.e. i load the kernel on tftp
and boot from that.)

Regards
