Dear ptp4l-devs,we try to sync embedded devices, which are only capable of PTP_TWO_STEP=FALSE (aka twoStepFlag=0 aka one-way-sync aka PTP_Sync=1) syncing, with our Ubuntu Linux host (System overview below). When we run the self build ptp4l via "./ptp4l -m -l7 -2 -H -i enp0s25 -E -f /etc/ptp4l.conf" (see config etc. below), the execution hangs for all ptp4l versions > 1.7 at "INITIALIZING to LISTENING on INIT_COMPLETE". If we comment the corresponding line [1] where ptp4l hangs, its start sending the SYNC_MESSAGE etc. and the log goes on with:
... ptp4l[5819.030]: config item enp9s0f0.ptp_dst_mac is '01:1B:19:00:00:00' ptp4l[5819.030]: config item enp9s0f0.p2p_dst_mac is '01:80:C2:00:00:0E' ptp4l[5819.088]: driver rejected most general HWTSTAMP filter ptp4l[5819.089]: ioctl SIOCSHWTSTAMP failed: Numerical result out of range ptp4l[5819.089]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[5819.089]: config item /var/run/ptp4l.logMinDelayReqInterval is 0 ...

When using twoStepFlag=1, the timestamps remain 0, but a FOLLOWUP_MESSAGE is sent with the correct OriginTimestampPrecise times.
We followed the instructions from [2] and [3] without success.We also tried another PTP hardware capable intel network card with e1000e driver with the exact same log messages. We also tried all versions from 1.8 to master branch, while version <= 1.7 ignores the twoStepFlag=0 option. However, software timestamping and twoStepFlag=1 works between two linux hosts
Does anyone see our fault or has similar issues? Kind regards, Timo[1] https://github.com/richardcochran/linuxptp/blob/d663a483c40939bad58301c256d86da1f3da6cc0/sk.c#L99 [2] https://doc.opensuse.org/documentation/leap/tuning/html/book.sle.tuning/cha.tuning.ptp.html [3] https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/deployment_guide/s1-synchronizing_the_clocks
