This question really should be asked on the linuxptp-users list instead. BTW, 18.04 is really old -- better check that your PHC kernel driver really supports time stamping of external inputs. > Steps : > compiled gpsd on target > # git clone https://gitlab.com/gpsd/gpsd.git > # cd gpsd > # scons --config=force && scons install Um, that has nothing to do with this project! The ts2phc program works (or should work) all by itself. > Command : > ts2phc -f ts2phc.cfg -m -s generic > ts2phc[503.770]: poll returns zero, no events > ts2phc[505.772]: poll returns zero, no events > ts2phc[507.774]: poll returns zero, no events > ts2phc[509.776]: poll returns zero, no events The PHC is not time stamping any edges at all.
