i use a motorola GPS card as my server, and the driver i choose is the
oncore driver(type 30). my linux version is 2.4.20 with pps patch, and the
ntp version is 4.1.2. after ntpd configured the card, it was most likely
just stay at some position to wait for the some condition to be satisfied.
in the log file 'clockstats' it print the following sentences time and time
again. 52857 53939.486 127.127.30.0 Resetting timing to Assert.
52857 53939.486 127.127.30.0 HARDPPS Set.
52857 53966.208 127.127.30.0 Resetting timing to Assert.
52857 53966.208 127.127.30.0 HARDPPS Set.
in the ntpq, i try cl command, and it prints below where the 'noreply'
always equals to 'poll'-2.
status=0101 clk_noreply, last_clk_noreply,
device="Motorola Oncore GPS Receiver", timecode=, poll=948, noreply=946,
badformat=0, baddata=0, fudgetime1=0.000, stratum=0, refid=GPS, flags=4
anybody knows what the ntpd is waiting for? i am very sure that the pps and
the serial signal have been received by the PC.
