The 1588 clock on the device looks like it can capture the current time from 4 different HW signals. Unfortunately, those signals all come from timer PWM outputs.
Maybe it's possible to cause a timer output from an external trigger (the PPS)? There is also a software initiated capture. Maybe it's possible for a PRU to set that in response to the PPS? If the code can be deterministic (and supposedly, that one of reasons for the PRUs), maybe just offset the timestamp by PRU code execution time would work. Lots of "maybe"s in there... -Dale _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
