STM32H723 PTP IEEE 1588V2 support

I am currently using STM32H723 MCU for a project. I want to use PTP to synchronise different peripherals that will send data and their timings need to be precisely synchronised. The reference manual has got a whole section for programming IEEE 1588 timestamping.

But going through the different files that implement the ethernet driver, I found this comment:

   -@- The PTP protocol offload APIs are not supported in this driver.

The offload feature is most vital to me. I am wondering whether that is an old message or if this driver still doesn't support hardware timestamping.

Has anyone have luck with this??

Hello @FranciscoRobaina , and welcome to the ST community,

Unfortunately, there isn’t an official PTP example provided by ST. However, you might find the following resources helpful for getting PTP to work on the STM32H723:
