Issue Description

We are deploying PTP synchronization on DRIVE AGX Orin with 6 radars connected to the 6 Ethernet ports of the MATE-NET J11 on switch 1.

  • PTP is correctly propagated to 5 out of 6 radars.
  • The only radar that never receives PTP is always the one connected to port 4 of the MATE-NET J11 on switch 1.
  • This behavior is consistent across two different AGX Orin boards with different radar : in both cases, the radar connected to port 4 does not receive PTP.

Based on NVIDIA’s documentation:

It seems that port 4 is configured with a different role (secondary), which might explain why PTP is not delivered to devices connected on this port.

Question

  • Is this limitation expected (port 4 configured as secondary, not propagating PTP)?

  • If so, is it possible to reconfigure port 4 to act as primary (like the other ports) so that PTP can be distributed to the radar connected on it?

5

Yes. For reconfiguration of port, you need to consult marvell to customize for your use case .

Thanks for your response.

To proceed with the reconfiguration of port 4 on the Marvell switch, could you please let me know if NVIDIA has a contact at Marvell that we can reach out to for support on this customization?

Alternatively, if there’s a recommended procedure or channel to initiate this request with Marvell.
