No PTP with Intel i210 on standard Ubuntu 22.04.1

[LaumiH]

Hi,

I cannot get ptp4l to work with an Intel i210 network adapter and the HAT/Pi.

The Pi is set up according to the standard config described in the WiKi, image version 1.0. The i210 is installed on a standard Ubuntu 22.04.1 Linux PC (kernel 5.15).

The Pi has linuxptp version 1.9, the PC 3.1.

I now run sudo ptp4l -q -i RT0 -f /usr/share/InnoRoute/ptp.conf -m -l 6 on the Pi, and the same on the PC.

Both assume the grand master role, while the i210 constantly outputs "bad message" errors. I ran the exact same configuration with a SOCe TSN switch in the middle, where both are able to synchronize, with the switch as grand master.

I already updated the Pi's linuxptp version, which had no effect.

I wonder why the Pi is not able to talk to the i210, but they are both able to synchronize with the TSN switch? The PTP packets look exactly the same, but the Pi sends them out padded to 70 bytes payload.

Hello,

I was able to get the HAT/Pi working as slave and I210 as master. LinuxPTP version: 3.1.1
