This is likely a bug in the vendor kernel.  You should ask them to fix
it for you.

Thanks,

[Linuxptp-users] Layer 2 ptp on Nvidia Orin

2023-04-10 Thread Greiner, Andreas 
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:
   Capabilities:

  ptpv2-l2-delay-req
(HWTSTAMP_FILTER_PTP_V2_L2_DELAY_REQ)
  ptpv2-event   
(HWTSTAMP_FILTER_PTP_V2_EVENT)

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
