Hi,
I am trying to implement PTP server for synchronize TDD base stations and I
successfully install all the packages and services in the centos 8
But phc2sys in fail status. Do you have any suggestion for that ?
[root@localhost log]# systemctl status phc2sys
● phc2sys.service - Synchronize system clock or PTP hardware clock (PHC)
Loaded: loaded (/usr/lib/systemd/system/phc2sys.service; enabled; vendor
preset: disabled)
Active: failed (Result: exit-code) since Tue 2019-10-01 05:25:52 EDT;
59min ago
Process: 4169 ExecStart=/usr/sbin/phc2sys $OPTIONS (code=exited,
status=255)
Main PID: 4169 (code=exited, status=255)
But phc2sys -w -s eno2 -m output work properly
[root@localhost log]# phc2sys -w -s eno2 -m
