Oh, sorry, I gave you the wrong command line. It is the -r flag that
needs repeating.
./phc2sys -a -r -r -m
FYI, the phc2sys man page says:
OPTIONS
-a Read the clocks to synchronize from running ptp4l and follow
changes in the port states, adjusting the synchronization direc‐
tion automatically. The system clock (CLOCK_REALTIME) is not
synchronized, unless the -r option is also specified.
-r Only valid together with the -a option. Instructs phc2sys to
also synchronize the system clock (CLOCK_REALTIME). By default,
the system clock is not considered as a possible time source. If
you want the system clock to be eligible to become a time
source, specify the -r option twice.

Did you see that? .. ^^^^^^^^^^^^^^^^^^^^^^
