sudhakar,
I am not sure I have followed your post.
Are you saying that when you power on your device it starts to show the shell screen after 40 secs?
And you also saying that the OS boot time from that is only 11 seconds, right?
Then, I assume, you've got a long BIOS POST time. Upgrade the BIOS or change the hardware so that the POST would take as less time
as possible (with some embedded BIOS implementation the POST time could be less than 1-2 seconds).
