Hi all,
I've been trying to run phc2sys but it kept print this message on the screen
and the system clock was found not able to sync to /dev/ptp0. My command was:
./phc2sys -w -s /dev/ptp0 -m
phc2sys[273995.639]: failed to read clock: Invalid argument
phc2sys[273996.639]: failed to read clock: Invalid argument
phc2sys[273997.639]: failed to read clock: Invalid argument
phc2sys[273998.639]: failed to read clock: Invalid argument
phc2sys[273999.639]: failed to read clock: Invalid argument
I am running kernel 3.7.5., intel I350 and linuxptp-1.4. I've found that the
print messages came from the function call: clock_gettime(clkid, &tsrc) at line
106 in phc2sys.c:
if (clock_gettime(sysclk, &tdst1) ||
clock_gettime(clkid, &tsrc) ||
clock_gettime(sysclk, &tdst2)) {
pr_err("failed to read clock: %m");
return 0;
}
I forced the code to ignore the error by commenting out "return 0", phc2sys
seemed to work fine; I mean the system clock was able to sync to /dev/ptp0
fine. Does anyone know why?
Thanks!
Calvin Pham
