    Hi Ashwini,

    Looking the output of your printenv, it looks like your boot_cmd is set to the following:

    bootcmd=run boot_rd

    This command will boot expecting a ramdisk to be loaded. Since you are using a jffs file system try to change your bootcmd as follows.

    "setenv bootcmd run boot_fs"

    "saveenv"

    "boot"

    I have not verified your enviroment variables are correct, so please let me know if this works.

    Regards,
