ptp / enet driver problem

andylime — Wed, 02 Dec 2020 13:27:59 GMT

I am porting the AN12149 ptp application note to the most recent SDK.

There are a very big differences between the fsl_enet.c FSL_ENET_DRIVER_VERSION (MAKE_VERSION(2, 3, 0)) and FSL_ENET_DRIVER_VERSION (MAKE_VERSION(2, 2, 3)), there are literally missing a lot of ieee1588 functionality like ENET_GetRxFrameTime just to mention one.

This makes it impossible to port the application.

It is somehow surprising that the library exist without being recently backwards compatible.

Do there exist any workaround to fix the incompatibility or an explanation ?

Regards Andy

Hello,

I'm interested in this code. Did you make any progress on this?

I too am looking at these same missing functions. We had AN12149-based PTP working with a (much) older version of the SDK, but it's hard to know where to start without ENET_GetRxFrameTime() and ENET_GetTxFrameTime() to name but two, these are such low-level functions.

Or is PTP basically not supported any more?
