Also when I check if my network interface supports PTP I get the following message. I think my NIC is not PTP capable? tony@tony-IdeaCenter:~$ ifconfig -s Iface MTU RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg enp3s0 1500 449521 0 0 0 1398083 0 0 0 BMRU enx0c379 1500 0 0 0 0 978 0 0 0 BMRU lo 65536 11220 0 0 0 11220 0 0 0 LRU tony@tony-IdeaCenter:~$ sudo ethtool -T enx0c379 Time stamping parameters for enx0c379: Cannot get device time stamping settings: No such device tony@tony-IdeaCenter:~$ Regards, *Tony* On Thu, Jun 8, 2023 at 10:19 PM Timothy Huang <tim.hu...@edgeq.io> wrote: > Hi, > > I'm guessing your PTP module is not loaded in the kernel you are running? > Have you tried manually loading the PTP module yet? > > To compile it as a built-in module, I think you need to enable these > configs in the kernel. > > [image: image.png] > > Regards, > Tim > > On Thu, Jun 8, 2023 at 9:43 AM Tony Josi <tonyjosi...@gmail.com> wrote: > >> Thanks Timothy for the reply, >> >> Unfortunately I can't find any PTP devices inside the /dev/ folder. >> >> Im trying the following demo: >> https://dev.ti.com/tirex/explore/content/mcu_plus_sdk_am243x_08_06_00_43/docs/api_guide_am243x/EXAMPLES_ENET_LAYER2_MULTI_CHANNEL_PTP.html >> Using the TI AM243x LP board. >> >> On the board side I'm getting the logs printed till above the line: Doing >> first adjustment >> >> The board is connected directly to the Linux PC via a USB to Ethernet >> adapter and LAN cable. >> >> I'm wondering if there is something that should be enabled in the Kernel >> to get it recognised? >> >> Regards, >> *Tony* >> >> >> >> >> On Thu, Jun 8, 2023 at 9:54 PM Timothy Huang <tim.hu...@edgeq.io> wrote: >> >>> Hi Tony, >>> >>> I can reproduce your problem by manually bringing down the ethernet >>> interface ptp4l is using.
