Hi Victor, Thanks very much for your reply. I understand that what you have sent the code will service the timer. What I want to do is reset the processor and reboot it. My code resetting the processor, but it is not rebooting. That is, it is not jumping to archStart function. Can you please help me ..in this regard.
