NXP iMX8M PLUS: eQOS: PTPv2 L2 support

pierluigi_p — Tue, 27 May 2025 10:07:38 GMT

Dear NXP support,

the Linux source code of eQOS driver manages the supported PTP features here

but we cannot find reference to L2 support.

Does the HW support L2 ?

If yes, is there any plan to add it ?

Thanks

Best Regards

Pier

Hi,

Thank you for your interest in NXP Semiconductor products,

What features of PTP L2 do you need? I would strongly recommend you to check NXP BSP, either Linux Factory or Real Time Edge.

i.MX 8M Plus EQOS IP includes L2 (filtering) support through MAC DA/SA and VLAN filtering, RTEdge supports:

as far as I can see from the kernel code, PTP L2 require dedicated support in the kernel driver

I'm not able to find any management for them in the eqos driver as provided in the offcial NXP BSPs.
Could you please confirm ?
Thanks

Best Regards
