Implementing linuxPTP with software Timestamping

Good afternoon.

I am trying to use linuxPTP on two Jetson Nano. Since the Nano doesn’t support hardware timestamping, I need to use software timestamping. I tried to look up guides for it but they don’t explain clearly what I am doing wrong.

Could someone direct me to some guides or even answered questions related to using software PTP on the Nano?

Thank you.

Below link may help on it.

This was the tutorial I used but they use hardware timestamping. I need software timestamping.
