STM32 + eth phy with ieee1588

hi everyone,

Does stm32 have any ptp integration manual? For example, I would like to use a DP83640 with an integrated ieee1588. And this phy contains PTP/SFD interrupt pins. Are there any pins in stm32h7 family or stm32f7 family for this interrupt? Or do I join any interrupt gpio and create my own routine? Or how to successfully implement ptp on stm32?

Thanks for the links. What I didn't find anywhere, if for IEEE1588 implementations it is necessary to have an eth phy with the integration of this protocol or a simple DP83826 is enough or a DP83640 is needed?

 

So my question is, are both DP83826 and DP83640 suitable for STM32F7orH7 to implement IEEE1588?
