Re: [Linuxptp-users] Bug in LinuxPTP

[Aman S. <ama...@gm...>]

Hi Richard,

Thanks for your reply.
We are facing one more issue, in one of our Laptop we are not able to
run linux ptp but it got compiled correctly.
Machine details:
OS: 12.04 ubuntu
Kermel version: 3.2.0-40-generic
Ethernet controller: INTEL 82579LM with e1000e kernel driver

Following are log messages:

sudo ./ptp4l -S -i eth0 -m -2
ptp4l[327.331]: port 1: get_ts_info not supported
ptp4l[327.464]: port 1: INITIALIZING to LISTENING on INITIALIZE
ptp4l[327.464]: port 0: INITIALIZING to LISTENING on INITIALIZE
ptp4l[333.464]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
ptp4l[334.032]: port 1: new foreign master 0023ae.fffe.1c6e61-1
ptp4l[334.469]: poll tx timestamp timeout
ptp4l[334.469]: port 1: send sync failed
ptp4l[334.469]: port 1: MASTER to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED)
ptp4l[350.472]: port 1: FAULTY to LISTENING on FAULT_CLEARED

We are not able to figure out why "send sync failed" is happening
interface is UP and connected to other linux machine with linuxptp
runnning.

Thanks for your help.
