Ok. I'm not super familiar with that device. From the output that clockcheck is seeing a jump, this indicates usually either a driver bug or that something else is setting the clock. You aren't (yet) running ptp4l in this scenario right? If you are, is it possible you've configured the client on this device to enter slave mode on accident? You might also try the -F and -S options of the phc2sys to enable step threshold offsets. (-F should be on by default but not be a good value in this case). > > > The output of ethtool -T eno1 is as follows: > > Time stamping parameters for eno1: > Capabilities: > hardware-transmit (SOF_TIMESTAMPING_TX_HARDWARE) > software-transmit (SOF_TIMESTAMPING_TX_SOFTWARE) > hardware-receive (SOF_TIMESTAMPING_RX_HARDWARE) > software-receive (SOF_TIMESTAMPING_RX_SOFTWARE) > software-system-clock (SOF_TIMESTAMPING_SOFTWARE) > hardware-raw-clock (SOF_TIMESTAMPING_RAW_HARDWARE) > PTP Hardware Clock: 0 > Hardware Transmit Timestamp Modes: > off (HWTSTAMP_TX_OFF) > on (HWTSTAMP_TX_ON) > Hardware Receive Filter Modes: > none (HWTSTAMP_FILTER_NONE) > all (HWTSTAMP_FILTER_ALL) > ptpv1-l4-sync (HWTSTAMP_FILTER_PTP_V1_L4_SYNC) > ptpv1-l4-delay-req (HWTSTAMP_FILTER_PTP_V1_L4_DELAY_REQ) > ptpv2-l4-sync (HWTSTAMP_FILTER_PTP_V2_L4_SYNC) > ptpv2-l4-delay-req (HWTSTAMP_FILTER_PTP_V2_L4_DELAY_REQ) > ptpv2-l2-sync (HWTSTAMP_FILTER_PTP_V2_L2_SYNC) > ptpv2-l2-delay-req (HWTSTAMP_FILTER_PTP_V2_L2_DELAY_REQ) > ptpv2-event (HWTSTAMP_FILTER_PTP_V2_EVENT) > ptpv2-sync (HWTSTAMP_FILTER_PTP_V2_SYNC) > ptpv2-delay-req (HWTSTAMP_FILTER_PTP_V2_DELAY_REQ) > > Regards, Jake ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
