Hi, I've just sorted this out.
Although I followed the guide I linked mostly, I did read this page regarding "known issues" and used the configure flags recommended there: http://ml.linuxpps.org/wiki/index.php/LinuxPPS_NTPD_support That page has bad advice it appears. After recompiling with the originally recommended flags, I get the desired PPS output on ntpq. It does feel like a bug though. Clearly I missed the flags required for both driver 20 and 22 in my configure script. If I put 22 in my ntp.conf, I got an event telling me, and you know it's broken. With driver 20, it said "ok" and never did anything. David, I tried alternating 20 and 22, they both work now for me. I didn't do anything special afaik. -Josh ________________________________________ From: [email protected] [[email protected]] on behalf of David Taylor [[email protected]] Sent: Friday, 28 December 2012 8:26 PM To: [email protected] Subject: Re: [ntp:questions] Using PPS On 28/12/2012 06:53, Kennedy, Paul wrote: [] > I use the type 20 driver on my pi, and PPS to the GPIO boards works a > treat with an $RMC or $ZDA string. > > regards > pk That's helpful to know, Paul. Do you mean "ports" rather than "boards", or are you using an add-on board? What modifications did you make to the kernel to get the PPS detected? -- Cheers, David Web: http://www.satsignal.eu _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
