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?

In addition to that, you should see the PTP device name by "ls > /dev/ptp*" if your interface is up. > > Thanks, > Tim > > On Thu, Jun 8, 2023 at 9:05 AM Tony Josi <tonyjosi...@gmail.com> wrote: > >> 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.
