pps1 -> cuau1 should do it. I am running 6.2 where pps1 -> cuad1 works fine.
Thanks, but actually, I had all that correct. (pps0 -> elan-mmcr, oncore.pps.0 -> cuau1, oncore.serial.0 -> cuau1). Unless you get pps from elan-mmcr, I'm pretty sure you don't pick up the special qualities of the high res NET4501 timer.
My error was to fat-finger a file name, the elan-mmcr driver doesn't like it when it doesn't have an input because you saved the file as "sysctl.con" instead of "sysctl.conf". So, for the archives, "Inappropriate ioctl" can be caused by not having the gpio lines properly configured.
Something else I discovered - somewhere along the line, NTP breaks with this - with both an Oncore and an Atom (PPS) refclock, NTP always marks the Atom as a falseticker, even if "server 127.127.22.0 true..." is specified, and even if they're consistently ticking within a few microseconds of each other. That happened with NTP 4.2.7p5_1. Going back to 4.2.4p5, they work fine together, although the Oncore gets marked as a "candidate" instead of a "peer".
