To be useful, the HW + driver must support Sync and Delay_req at the same time. > My ethernet driver only support specific PTP EVENT ,like SYNC or DELAY_REQ. > and couldn’t support any kinds of event for PTP. > so does linuxptp support this kind of ethernet ptp ? No. And you can't get very far with only Sync, for example. > or anyone who could give a piece of advice about how to enable ptp for this > kind of driver? Talk to your HW developers, and tell them to fix their stuff.
