Synching PPS Output to PTP or NTP Service

Robotics & Edge Computing Jetson & Embedded Systems Jetson AGX Xavier

This is what I’m trying to achieve:
1.) AGX output PPS
2.) AGX synched with PTP from external device
3.) PPS output synched with PTP

I have got 1 and 2, but not 3. The PPS is not disciplined with PTP.

Is there a setup of the product that supports the configuration I’m looking for?

I have been through quite a few forums attempting to solve this issue. The closest we come on AGX is PPS input to drive NTP here (unresolved):
NTP with PPS Support on Xavier AGX - Jetson & Embedded Systems / Jetson AGX Xavier - NVIDIA Developer Forums

And PTP to drive PPS output here (original question unresolved, solved by modifying driver code in software, but modified code not provided)
PTP synchronization and PPS output from Nvidia NX - Jetson & Embedded Systems / Jetson Xavier NX - NVIDIA Developer Forums

Hi,
Please share which release you are using, Jetpack 4.6.3 or 5.1. And is it possible to replicate the issue on Xavier developer kit? Not sure if you have tested it on developer kit and observe the issue also.

Hi,

Not sure if this is what you want to do.
