802.1AS PTP example code on the RT1180

ViorelDv — Mon, 23 Sep 2024 15:18:47 GMT

Hello everybody,

I just received the RT1180 and I want to check the PTP on this board.

On the RT1170 there is the example code evkbmimxrt1170_enet_qos_txrx_ptp1588_transfer_cm7.

Do we have something similar for the RT1180 ?

I saw that fsl_enet_qos.h looks tot to be available in the SDK for RT1180.

Thank you for your support,

Viorel

Hi @ViorelDv

Do you need PTP implementation using an stack? Does our GenAVB stack works for you? https://github.com/NXP/GenAVB_TSN

Hello @diego_charles ,

Thank you for the feedback.

I suppose that the GenAVB might also work.

Are the interfaces ENET_Ptp1588SetTimer/ENET_Ptp1588getTimer no longer supported for RT1180?

Regards,

Viorel

Hi @ViorelDv

Thank you for your reply as well!

I checked and , at this moment this functions/interfaces are not implemented in the RT1180SDK. But I do not know if they will be added to upcoming SDK versions.

Are you in a hurry to evaluate PTP? Do you need more help?

Hi @diego_charles ,

Thank you for the feedback.

We were using in one of our projects an implementation with RT1170 using ENET_Ptp1588SetTimer/ENET_Ptp1588getTimer.

I was hopping that I will be able to port the code, more or less, directly on RT1180.

In this case I think we will have to try to adapt to GenAVB.

Regards,

Viorel
