I have enabled PTP on RPi3 B+ by following the instruction given here. Now can you help me with a code to test PTP on Rpi. I am trying with one code, but with "SOF_TIMESTAMPING_TX_SOFTWARE" an input argument, but getting some error related to "ioctl" . (http://www.cs.fsu.edu/~baker/devices/lxr/source/2.6.31.13/linux/Documentation/networking/timestamping/timestamping.c) ==================================================== pi@raspberrypi:~ $ sudo ethtool -T eth0 Time stamping parameters for eth0: Capabilities: software-transmit (SOF_TIMESTAMPING_TX_SOFTWARE) software-receive (SOF_TIMESTAMPING_RX_SOFTWARE) software-system-clock (SOF_TIMESTAMPING_SOFTWARE) PTP Hardware Clock: none Hardware Transmit Timestamp Modes: none Hardware Receive Filter Modes: none ==================================
