    Hi slsnios,

    > atleast ,now kernel is able to find which is fs is there.

    Great!

    > should be not worked when same fs is used as romfs.bin

    You should forget about romfs.bin and just populate the cramfs with the necessary files -- and

    edit the init scripts to suit your own needs. Here's what I typically use:
