[Linuxptp-users] ptp4l does not return delay response message

[Kevin Choo]

Hi all,   I am trying to test ptp implementation with ptp4l as the ptp master on a Linux pc and another ptp slave on evaluation board. Facing a weird issue where the ptp4l in master mode does not return delay response message when the slave is sending delay request message.   Ptp4l log: [kevin@localhost etc]$ sudo ptp4l -f /etc/ptp4l.conf -i enp3s0 -m ptp4l[3024235.167]: selected /dev/ptp0 as PTP clock ptp4l[3024235.168]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[3024235.169]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE ptp4l[3024241.381]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES ptp4l[3024241.381]: selected local clock 6805ca.fffe.1cb488 as best master ptp4l[3024241.381]: assuming the grand master role   Some preliminary testing that I have done but with no luck: Check that ptp4l is listening to port 319 and 320 with netstat -anpe Disable firewall (in case firewall is preventing the udp port listening) Look into the packets with wireshark. Detect no issue with the sync, follow-up and delay req packets.   Appreciate it if anyone can suggest any pointers for me to continue debug on this matter.   Thank you.   Best regards, Kevin
