Do S32G ports support 802.1AS 2020

[Toooong]

Hi,

Shown as GMAC Subsystem RM, the GMAC0 port supports for TSN time synchronization (802.1AS-Rev). So do PFE_MAC ports, indicated in S32G Product brief(1st pic). Thus, are those ports support 802.1AS-2020? It seems that there are some tiny difference between 1AS-REV and 1AS-2020(2nd pic).

Looking forward to your reply.

Best wishes

Hello, @Toooong

Thanks for the feedback.

Since the multiple domains are included in the 802.1AS-REV, while GMAC could support the spec from hardware perspective,  then I think this feature could be supported by the GMAC.

Thanks for the questions.

According to the latest S32G2RM and GMACSUBSYSRM, the Time synchronization standard based is IEEE 802.1AS-rev, not 802.1AS-2020.

Hi chenyin,

Thanks for your reply.

As mentioned before, GMac port does support 802.1AS-Rev protocol. Does Gmac support multi-domains function in time synchronization?

Looking forward to your reply.

Best wishes.
