#187560 - Missing information
Responding to: Nikunj Kubadia's previous message
Nikunj Kubadia said:
My query is, can it be Hardware issue or is it software related issue?

And answer is yes - it can be a hardware issue. And it can be a software issue.

You haven't told us what chip.
You haven't told us what the reset circuit looks like.
You haven't told us how your processor pin is connected.

But a good hardware design should keep the processor pin in a fixed "idle" state all through the reset - and all through a power up. First when the software is up and running, should there be a way to set the output signal to the "active" state.
