RT1064 - AN12149 (IEEE 1588 PTP) - SDK 2.13.0+

austin_morlan — Mon, 23 Sep 2024 22:29:19 GMT

Hello,

I am attempting to enable PTP on an RT1064-based device using the methodology presented in AN12149 but have discovered that much of the low-level functionality used in that demo is no longer present in recent SDK versions (e.g., 2.13.0) such as ENET_GetRxFrameTime() and ENET_GetTxFrameTime() which use ENET_Ptp1588SearchTimeRing().

Is PTP on the RT1064 still supported? The txrx_ptp1588_transfertxrx_ptp1588_transfer example is not helpful because it uses raw ethernet frames while I need FreeRTOS+lwip.

Thank you.

From Howard Liu's response in this thread, the big question is: how to get TX and RX frame times correctly with recent versions of the SDK?

Hi @austin_morlan ,

Thanks for your interest in NXP MIMXRT series!

I asked an internal expert about this issue and the feedback I got was that due to changes in the underlying code, it is currently not possible to get timestamps using the previous API. We will update the software for this AN, but so far there is no way to get the exact timeline. Sorry for any inconvenience caused by this. I will also keep you updated as soon as newer software is released.

Best regards,
Gavin

Can you tell me how to go about getting timestamps with the current API? I don't need an entirely new AN software release, just guidance on the new method of getting PTP timestamps.

Thank you.

Hi @austin_morlan ,

Since this is a public community, I can't upload unreleased software here, including code snippets. Can you go to the portal on the official site and submit a new ticket? Please indicate the assignment to me and then I will try to help you with some ideas through the system.

It's probably not an easy thing to do since the underlying layer has changed, but at least some code snippets are possible. Thanks for your collaboration in advance.

Best regards,
Gavin
