RTC Problem in Olimex AT91SAM9260

Hi all,

I have a problem in accessing RTC in AT91SAM9260. While in Boot process my controller can not read the time.

rtc-at91sam9 at91_rtt.0: rtc core: registered at91_rtt as rtc0

rtc-at91sam9 at91_rtt.0: rtc0: SET TIME!

after some boot messages i can see the message like,

rtc-at91sam9 at91_rtt.0: hctosys: unable to read the hardware clock

how can i fix this issue. Can anyone give solution for this problem?

We are stuck in this problem long time.
