Fantastic. Thanks @royk! So it looks like the answer is, Yes, the Orange Pi 5 board does have PTP hardware timestamping support. I can only make one post per day, so asking additional questions if you don't mind. What OS and version are you running? I'm guessing armbian, but just want to make sure.

I'm looking for information about the Ethernet chip on the Orange Pi 5. I need an SBC that has PTP hardware timestamp support (IEEE 1588). According to OrangePi.org, the Orange Pi 5 has the Motorcomm YT8531C, but I have not been able to find documentation that provides the answer about hardware PTP support. Most likely it does not, but I'd like to confirm on an actual device before purchasing one. If you have an Orange Pi 5, you can test this with this command: ls /sys/class/net |xargs -n1 ethtool -T If there is someone that is willing to run this command and post the output, I would appreciate it very much. Note: This is a cross-post from iot.stackexchange. The only response I got there after three days was to check here on Armbian. So here goes.
