    Hi Wojciech, Quick update. I have your branch of PTPd working on the Altera Cyclone V SoC. This infers (implies?) that PTPd should work on the Altera Arria V SoC, too, as both of these products use the eMAC licensed from ST Microelectronics. Thanks again for all your help! -Allan

    Hi Wojciech, I really appreciate the work you've done on implementing H/W timestamping -- Very nice! A little more about this environment: The Cyclone V SoC uses the ST Microelectronics EMAC, and the O/S I'm using is a Linux 4.10 kernel -- I'm not seeing txTimestampErrors as much as I'm seeing rxTimestampErrors errors: ~~~ 2017-06-29 22:31:58.763006 ptpd[558].(info) transport: ======= transport 'Event' error counters ====== 2017-06-29 22:31:58.763155 ptpd[558].(info) transport: rxErrors: 0 2017-06-29...

    Hi! The Altera Cyclone V Soc has IEEE1588-2008 support in the MAC hardware. I have the 'wowczarek-2.3.2-libcck' branch working, mostly. The problem is, is that the sequence-numbers will occasionally get out of sync -- I'm including a snippet of the log-file that indicates this: 2017-06-29 20:58:05.189102 ptpd[558].(debug1) Received an empty PTP message (this should not happen) - ignoring 2017-06-29 20:58:05.189197 ptpd[558].(debug1) ==> DelayResp message received, sequence 36414 2017-06-29 20:58:05.189241...
