RTC problem in LPC2378

The RTC of LPC2378 is corrupting its Hours field.

From the RTC of LPC 2378 we will getting Day,Month,year,Hours,Minutes,Seconds fields, in genral RTC will be updated continiously..but one odd time the hours field is geeting corrupted.

The following are the date time deatls..

15/02/11 21:01:09
15/02/11 21:01:10
15/02/11 21:01:11

15/02/11 21:58:56
15/02/11 21:58:57
15/02/11 21:58:58

15/02/11 17:58:59 -----------> corrupted here(The hours field is abruptly jumped from 21 to 17)
15/02/11 17:59:00

Can anybody may explain what might be the problem? and solution to this type of problems

  • I working for last 6 years on ARM …At one of the project GE POWER by using NXP - LPC2378 I get these type of problems. but finally I found solution ….

    Problem: when I using max number UART’s(3) handling of IRQ and QUE and SD CARD (time) writing in data in to it. Not only Hr..and also sec. and cyclic time of total task.

    Solution : I isolate the each function and checking .only RTC I never got error. then I tried to increment the delay cyclic time of total task.don't use RTC PULSE for WDT
