6.8.5 RTC Testing

The development board contains a hardware clock to save and synchronize
the system time. A test can be accomplished with the following steps:
1. Set the system time as Mar 22 20:00:00 2012
root@SBC8600: # date 032220002012
Thu Mar 22 20:00:00 UTC 2012
2.
Write the system clock into RTC
root@SBC8600: # hwclock -w
3. Read the RTC
root@SBC8600: # hwclock
Thu Mar 22 20:00:10 2012 0.000000 seconds
We can see that the RTC clock has been set as Mar 22, 2012; the system
clock will be saved in the hardware clock.
4.
Restart the system; enter the following commands to update the
system clock
root@SBC8600: # hwclock -s
root@SBC8600: # date
Thu Mar 22 20:01:30 2012 0.000000 seconds
We can see the system time is set as hardware time.
