Hi,
can someone please give me a hint to find the correct settings for my problem.
I have a master and two slaves. I use Level2 and E2E mechanism for syncing.
The ptp hardware clock seems to be adjusted correct but with phc2sys i can't
set the RTC on the same value as the PHC. It is 36 seconds away like TAI-UTC.
Here are my calls and the logs:
