Hello,
we are currently trying to use ptp4l on a NVIDIA Orin to sync with a couple of
sensors using layer 2 ptp.
However, we get an error when starting the master instance on the Orin.
uam@hubble:~$ sudo ptp4l -i eth0 -m -2 -l 7
ptp4l[922.980]: selected /dev/ptp0 as PTP clock
ptp4l[923.053]: driver rejected most general HWTSTAMP filter
ptp4l[923.059]: ioctl SIOCSHWTSTAMP failed: Numerical result out
of range
ptp4l[923.120]: port 1 (eth0): INITIALIZING to FAULTY on
FAULT_DETECTED (FT_UNSPECIFIED)
ptp4l[923.121]: port 0 (/var/run/ptp4l): INITIALIZING to
LISTENING on INIT_COMPLETE
ptp4l[923.121]: port 0 (/var/run/ptp4lro): INITIALIZING to
LISTENING on INIT_COMPLETE
As far as I can tell it should be supported by the hardware though, as this
output of ethtool suggests:
uam@hubble:~$ ethtool -T eth0
Time stamping parameters for eth0:

We are using these versions:
ptp4l: 3.1-00224-gd4adf87
kernel: 5.10.104-tegra
Are there any mistakes on our side? What else can we try?
Kind regards,
Andreas
