Hello,

When we enabled profile writing with nvsipl sample, we noticed that the time logged into the CSV is not PTP time . This is the case of raw capture. Is there a way to get the PTP time of each incoming camera frame and not TSC SOF time in TSC ticks? The reason is I cannot relate the camera to the lidar frame which has PTP time embedded.

I did see the below ticket but I haven’t tried the changes recommended. Wanted to check first with Nvidia team.

Thanks!!

To correlate PTP time with TSC time in NVSIPL samples, you can refer to the NVPPS_GETPARAMS function as mentioned in the NvPPS document section. This function provides the necessary parameters for obtaining the correlation between PTP and TSC times.
