Hello,
I could make ptp4l working on Raspberry Pi, then I'd like to write about it. - Raspberry Pi 3 Model B - write image of Raspbian Jessie with Pixel to microSD - installed linuxPTP v1.8 - installed ethtool *** Rebuilding kernel configuration *** (1) Make directory of kernel $ cd $ mkdir kernel $ cd kernel (2) Download kernel $ git clone --depth=1 https://github.com/raspberrypi/linux $ sudo apt-get update $ sudo apt-get install bc (3) Configuration of kernal $ cd linux $ KERNEL=kernel7 $ make bcm2709_defconfig (4) Configuration with menuconfig $ sudo apt-get install libncurses5-dev $ make menuconfig Activate following three configuration with "menu-config" CONFIG_PPS CONFIG_NETWORK_PHY_TIMESTAMPING PTP_1588_CLOCK Save configuration. (5) Modify ethernet driver Search "drivers/net/usb/smsc95xx.c", and edit it with vi editor. Add a sentence " .get_ts_info = ethtool_op_get_ts_info," to end of " smsc95xx_ethtool_ops = " static const struct ethtool_ops smsc95xx_ethtool_ops = { .get_link = usbnet_get_link, .nway_reset = usbnet_nway_reset, .get_drvinfo = usbnet_get_drvinfo, .get_msglevel = usbnet_get_msglevel, .set_msglevel = usbnet_set_msglevel, .get_settings = smsc95xx_get_settings, .set_settings = smsc95xx_set_settings, .get_eeprom_len = smsc95xx_ethtool_get_eeprom_len, .get_eeprom = smsc95xx_ethtool_get_eeprom, .set_eeprom = smsc95xx_ethtool_set_eeprom, .get_regs_len = smsc95xx_ethtool_getregslen, .get_regs = smsc95xx_ethtool_getregs, .get_wol = smsc95xx_ethtool_get_wol, .set_wol = smsc95xx_ethtool_set_wol, .get_ts_info = ethtool_op_get_ts_info, }; (6) Name extraversion of rebuilding kernel $ cd ~/kernel/linux $ vi Makefile edit extraversion in Makefile such as; EXTRAVERSION = ptprpi (7) Building kernel $ make -j4 zImage modules dtbs $ sudo make modules_install $ sudo cp arch/arm/boot/dts/*.dtb /boot/ $ sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/ $ sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/ $ sudo scripts/mkknlimg arch/arm/boot/zImage /boot/$KERNEL.img (8) Reboot in new kernel $ sudo shutdown -r now ---------------------------- In my case, ptp4l on rpi has become working with these procedure.
