Hi, well im using the modified driver from sourceforge (see post of Jake). Therfore I only can use software timetamping, because HW-timespamps are not supported. If i dont use HW timestamping then I dont need to pick an /dev/ptp (I dont have one). After your information I changed to using a config file. Did I do it like you ment? Adding the tx_timestamp_retries? I tried several different numbers. Always the same error. The command I use is: ptp4l -i eht2 -f /etc/ptp4l.cfg the config is: [global] # logging_level 6 tx_timestamp_retries 100 use_syslog 0 verbose 1 time_stamping software And I still get the same error than before: > ptp4l[98.033]: port 1: get_ts_info not supported > ptp4l[98.035]: port 1: INITIALIZING to LISTENING on INITIALIZE > ptp4l[98.035]: port 0: INITIALIZING to LISTENING on INITIALIZE > ptp4l[104.035]: port 1: LISTENING to MASTER on > ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES > ptp4l[105.041]: recvmsg tx timestamp failed: Resource temporarily > unavailable > ptp4l[105.041]: port 1: send sync failed > ptp4l[105.041]: port 1: MASTER to FAULTY on FAULT_DETECTED > ptp4l[121.043]: port 1: FAULTY to LISTENING on FAULT_CLEARED > ptp4l[127.043]: port 1: LISTENING to MASTER on > ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES > ptp4l[128.049]: recvmsg tx timestamp failed: Resource temporarily > unavailable Thanks, Benny -----Ursprüngliche Nachricht----- Von: Keller, Jacob E [mailto:jac...@in...] Gesendet: Dienstag, 19.

Can you show me the command you use to run ptp4l? Second, you may need to modify the config file to increase the tx_retries value in the config file (and pass that config to ptp4l's command option) Basically, the part may not be returning the tx timestamp on the socket fast enough. If you increase the tx_retries count to a fair bit higher that may resolve the particular error. - Jake > -----Original Message----- > From: Tim...@de...
