[Linuxptp-users] ptp4l use case

[Drasko D. <dra...@gm...>]

Hi all,
cam somebody please clarify me some ptp4l usage.

I am using two pandaboards, one should be clock master to the other
and my need is to have a minimal clock offset between them.

I am starting on master (server) side :
root@panda_master:/linux-ptp# ./ptp4l -S -i eth0 -m -l5
ptp4l[109238.352]: port 1: get_ts_info not supported
ptp4l[109238.355]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[109238.356]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[109244.355]: port 1: LISTENING to MASTER on
ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES

and on slave (client) side :

root@speaker:/linux-ptp# ./ptp4l -S -i eth0 -s -m -l5
ptp4l[109513.813]: port 1: get_ts_info not supported
ptp4l[109513.817]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[109513.817]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[109514.583]: port 1: new foreign master 0e1851.fffe.028b34-1
ptp4l[109518.583]: selected best master clock 0e1851.fffe.028b34
ptp4l[109518.583]: foreign master not using PTP timescale
ptp4l[109518.583]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE
ptp4l[109521.607]: port 1: UNCALIBRATED to SLAVE on MASTER_CLOCK_SELECTED


Can somebody please give me information what does "UNCALIBRATED" and
"RS_SLAVE" means. Can you please clarify this line :
ptp4l[109521.607]: port 1: UNCALIBRATED to SLAVE on MASTER_CLOCK_SELECTED

Is there a way to get some more log messages, and to see timestamps
sent/received for further debugging and examination ?

Kind regards,
Drasko
