Hi,

       I am using Omapl138 internal RTC for one of my project, I want to know the importance and usage of  SWRESET bit of Oscillator register, i have found few issues in my internal RTC

   1. It has been observed  that seconds, minutes, hours registers were not updating, but i can see in status register The Run bit  of  RTC is set, then after forcefully enabling the SWRESET bit of oscillator register, the seconds, minutes, hours       registers started updating.

But as per spruh77a , section 28.2.10 a software reset should be performed during initial power on, but if i do software reset, all previous date and time information will be lost, then how to over come this.

I dont know where the exact problem, kindly help me in solving this issue.
