Subject: [ECOS] System clock runs slow
Date: Thu, 24 Oct 2013 20:35:00 -0000 [thread overview]
Message-ID: <F1F0A58F-038B-4CD9-80B2-8217E5122592@netic.com> (raw)
Hi all,
I'm running an LPC2212 board with eCos 2.
The board also has a dallas clock chip for wallclock.
SNTP is also configured and working.
What iI've observed is that the system clock looses about 3 seconds after 18 minutes when compared to both the wallclock and NTP.
I've checked the clock divisor settings and that's fine.
Interrupt nesting is enabled. It has a 10Mhz crystal and PLL takes that to 60Mhz.
I'm looking for ideas. How can I troubleshoot this? What could be the cause?
Thanks ...Laurie:{)
