I'm trying to program internal RTC of LPC1768 controller, When I run my program I get different (random) date and time on different LPC1768 boards (I'm trying on 3 different boards). i.e. on one board date is :- 1/2/1878, on 2nd board 30/11/3036 etc. I never get date and time which I have defined in my program.
What could be the issue, pls help.
