Subject: problems with MPC8xx internal RTC !?
Date: Wed, 29 Jan 2003 10:05:46 +0100	[thread overview]
Message-ID: <3E37996A.40302@imc-berlin.de> (raw)


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!!!

rdate:   Wed Jan 29 10:03:58 2003
date:    Wed Jan 29 10:04:04 CET 2003
hwclock: Wed Jan 29 10:04:04 2003  0.000000 seconds

Any ideas?

Thanks,

Steven
