Hello,

Is there any update on the topic?

Is there a way to change clock sync mechanism to E2E on the launchpad?

802.1AS -2020 does not support E2E for PTP. Can you please clarify the requirements? Do you require E2E 1 step or 2 step? Layer 2 or Layer 3 (UDP) ? 2 step implementation can be done via stack but SDK version does not support it !

Hi Konstantin,

Adding on top of PratheeshGangadhar response. 

SDK limited only for "802.1AS gPTP profile" support - according to IEEE 802.1AS gPTP profile it restricts to use E2E mode/measurement.

We require E2E on Layer 3, it would be good to have 1 step and 2 step sync. Is it possible? What do you mean by can be done via stack? Does it mean changing the SDK accordingly?

Yes, you need to modify/implement E2E 2-step in the gPTP stack present in the SDK. 1-step requires changes in the PRU ICSS firmware and there are no plans as of now to support 1-step.
