Hello, I am using linuxptp-3.1 version, I am running ptp4l slave instance in UDPv6 mode in beagle bone black using cmd" sudo ptp4l -i eth0 -6 -m -s"
And running ptp4l master in UDPv6 mode in HP Linux machine. "sudo ptp4l -i eth0 -6 -m" I am getting tx_timeout issue on beagle bone black. I increased the tx_timestamp_timeout but no success.~ $ sudo ptp4l -i eth0 -6 -m -s ptp4l[9329.908]: selected /dev/ptp0 as PTP clock ptp4l[9329.923]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[9329.925]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[9330.584]: port 1: received SYNC without timestamp ptp4l[9331.584]: port 1: received SYNC without timestamp ptp4l[9331.586]: port 1: new foreign master 10e7c6.fffe.431ac7-1 ptp4l[9332.584]: port 1: received SYNC without timestamp ptp4l[9333.584]: port 1: received SYNC without timestamp ptp4l[9334.584]: port 1: received SYNC without timestamp ptp4l[9335.584]: port 1: received SYNC without timestamp ptp4l[9335.585]: selected best master clock 10e7c6.fffe.431ac7 ptp4l[9335.585]: port 1: LISTENING to UNCALIBRATED on RS_SLAVE ptp4l[9336.585]: port 1: received SYNC without timestamp *ptp4l[9336.803]: timed out while polling for tx timestamp ptp4l[9336.804]: increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug ptp4l[9336.804]: port 1: send delay request failed ptp4l[9336.804]: port 1: UNCALIBRATED to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED) The kernel in beagle bone black is 4.14.224.
