Hello,
as I did not receive an answer since a while, I try to further clarify our problem:
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 the following 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
Our current understanding is that the Orin should support ptp via L2, due to the following output of the ethtool:
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?
