I have to admit I know nothing abut Linux serial PPS. My guess is I
need to somehow set this up before I try to get it to work with NTP.
My clockstats file is filled with the the messages quoted below. Is
there something I can read. I've build ntpd with the required pps
support, have the "correct" Linux kernel and header files, made links
in /dev. Hard to know what's missing. The error messages are not
very helpful
55609 21559.296 127.127.30.0 ONCORE[0]: ONCORE: oncore_get_timestamp,
error serial pps
55609 21589.292 127.127.30.0 ONCORE[0]: ONCORE: oncore_get_timestamp,

For things like this, your best bet is to look at the source code.
Usually greping for the text in the error message won't get very
many hits.
I took a quick look. I think it's trying to tell you that it's not
getting a PPS pulse.
Do you have a scope? Is the hardware making PPS pulses? How wide are
they? ...
or even a LED + diode + resistor will be enough to show if there is
a pulse. Radioclkd2 can be used in debug mode to confirm the single
DCD pulse and width.
