Are there any other error messages from ptp4l? What does ethtool -T print for the interfaces? If they share the PHC, as suggested by the timemaster output, you would need to use the new virtual clock feature of the kernel (available since 5.14, but 5.18+ is recommended) in order to get hardware timestamping working on both of them. You would need to build linuxptp from git. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
