OMAPL132 RTC

Hi There,

We are using internal RTC of OMAPL132 with 20ppm external crystal.

There is a remarkable 5 or 6 second delay per day and it is varying with different cards, even if we are running from main supply (not from backup battery). 

We tried different values of crystal load capacitance, but RTC failed again.

Any help will be appreciated.

Thanks
