Hi,
when i run the OC mode for the SLAVE clock to sync the time from the
master
clock, at first, the sync works fine, the offset is also fine, but the
offset becomes a very large value, i did some debugging and printed
the ppb
in kernel code api adjfreq, the ppb value is an abnormal value when
the
offset become a very larger value in linuxptp debug information. that
is to
say, the calculated frequency value in linuxptp triggers the abnormal
offset.
It could be a HW/driver issue. Do you have a ptp4l/phc2sys log showing
the offset and frequency values increasing?
Hi Miroslav, this is Roger, thanks for the reply.
Attached is the ptp4l log I captured, please help check it. the jitter
occurs as below log.
byw, I also printed the ppb value passed from linuxptp to kernel space
as "[ 194.207329] **********kernel adjfreq get ppb: fffffffd".
