Hello we are trying to utilize Novatel SPAN-IGM-A1’s GPGGA and PPS signals on AGX side. PPS signal is connected to the GPIO/PPS connector’s 3rd pin and its ground is on 5th. Also from UART with baud rate we feed GPGGA messages to the AGX. With ‘cat /dev/ttyTHS1’ we can see that gpgga messages are arriving to AGX correctly.
Our problem is that we couldnt utilize this messages’ time in AGX. For ex. when running sample_timesensor with live data, timesensor sends a log which is ‘TimeSensor: failed to acquire utc sensor timestamp, DW_TIME_OUT’ repetitive.
How can this issue be solved? How can we correctly utilize the timesensor across the system?


Dear @kaltinok,
My apologies for late reply. Could you share the complete logs you notice for checking with internal teams. And also please share the connection pictures/details
