Hi,
I'm pretty new to the PTP/IEEE1588 implementation. In fact, I never done an Ethernet design either, not from software or hardware side.
So forgive me if the answers to my questions are pretty obvious.
I wonder how to create/send (sync) messages, especially when layer2 messages are used. I’d assume the CPU/MAC has to assemble the messages, write them into the PHY via the MII interface and the PHY will than add the timestamps to the message.
My question is if there’s a way to let the PHY create the message on its own. I don’t have direct access to the MII in my application and I’d like to know if it’s possible to use PTP in this situation.
I think it is not possible but I might be mistaking.
