    RAM is a volatile memory technology so will lose its state when you remove power.

    If you want to preserve state over power / reset cycles you either need (1) a battery backed up RAM with a low power state, or (2) save to flash which you can then restore at boot time.


    Thanks for the reply.
    But that is what I am asking in my previous post that I am not able to save it in flash. Can you please provide some demo application or if you can provide me with any link, I can go through to understand that how I can save it in flash.
