Hi there,
I am using an MPC855T, external clocked with 16 MHz. Using the internal PLLs it
runs at 80MHz/40Mhz. An 32.768KHZ crystal is connected to clock the MPCs
internal RTC. A battery is there as well.
All seems to be fine. But I realized that the RTC runs too fast. It seems to be
releated to systems restarts.
It tested. After 25 reboots the RTC is already SIX seconds ahead!!!

hwclock: Wed Jan 29 10:04:04 2003 0.000000 seconds
Any ideas?
Thanks,
Steven
