Hi, I'm trying to use PTP on my linux machine:
*OS information:* Operating System: Ubuntu 20.04.5 LTS Kernel: Linux 5.15.0-71-generic Architecture: x86-64 This is the default official Ubuntu version that I have installed from the .iso image available from the Ubuntu website. Not a custom built OS. I have installed *linuxptp *with the following command: sudo apt install linuxptp But when I try running ptp4l with the following command: sudo ptp4l -i enox0c379 -m -2 -P -l 6 -q -f $HOME/ptp_config.cfg I get the following error message: ptp4l[890.371]: ioctl SIOCETHTOOL failed: No such device ptp4l[890.371]: PTP device not specified and automatic determination is not supported. Please specify PTP device. failed to create a clock Here is the contents of $HOME/ptp_config.cfg: [global] tx_timestamp_timeout 400 logMinPdelayReqInterval 3 logSyncInterval -4 logAnnounceInterval 0 How can I specify the PTP device, Isnt it the network interface that I have already specified? Thanks for your help Regards, Tony
