Hi,

For PCIE, I have the following two questions about time synchronization:

1. Does PCIE support hardware time synchronization? Or does it only support software time synchronization?

2. How can I turn on its time synchronization function?

Regards,

Yang

Hi Yang,

No gPTP for PCIe. For PCIe there is PTM for time synchronization between EP and RC, although this feature was deferred and not in our SDK.

But from the logs, I assume you want PTP for the network card that is connected via PCIe, instead of time synchronization between the SoC and PCIe network card.

Does the MVL Switch support PTP?

Hi，

You are right. I have asked about MVL FAE.
