Maybe have a look at this page: http://doc.ntp.org/current-stable/drivers/driver28.htmlSearch that page for "flag1". There should be 2 hits about a constraint in the initial time offset ("Mode-independent post-processing"), and how this can be disabled by setting flag1 to 1. Maybe this helps. Regards, Martin
Thanks for that, Martin. I knew the capability had to be /somewhere/ but I couldn't find it! However, in this case the RTC was not being driven correctly, and it was losing its setting under some circumstances - I think the battery/super-capacitor was being disconnected over power-down! I was pointed to the notes about correcting the register settings so that this wasn't done, and backup power was kept. I wrote this up in a small note: https://www.satsignal.eu/raspberry-pi/Uputronics-RTC.html Cheers, David -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email: [email protected] Twitter: @gm8arv _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
