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 1= 8 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:{) -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
