I hope what I want to achive is simple, but looking at some posts it doesn’t look that straight-forward.
I want to synchronize a Jetson Orin Development Kit via Ethernet Precision Time Protocol (PTP) and I want to measure accuracy of that synchronized time to a time-master by comparing PPS outputs of the time master and the Jetson Orin.
So: Is there a possibility to output a PPS signal based on a system-time or synchronized PTP time on one of the pins of the I/O-rows of the Orin Development Kit?
Thanks for the reference @KevinFFF. Since I wrote that I want to output a PPS signal, the other thread doesn’t seem to help me.
There needs to be a possibility for the Orin Development Kit to trigger a pin once per second, right? If it is triggered at the start of every second and the system time is synchronized using PTP, I should be able to derive the precision of the sync to another sync’ed node on the network.
Sorry that I don’t have the experience with this use case(output a PPS signal)
Do you see any document for this use case? Or which driver is used for output a PPS signal?
Sorry, but I don’t really understand what you mean by “document for this use case”. I haven’t looked at NVIDIA provided manuals yet.
I also don’t know which driver is used to output a PPS signal. I would think that’s a system setting which can be set in preparation of the image!?
For your use case, it seems you would need a driver to control and output the signal, not just a system setting could implement.
Output the PPS seems not default supported feature and there’s no driver to handle this currently.
