I have a design involving a DP83630 and an STM32, and an external PTP server using L2.
I'd looking to maintain a timer on the STM32 with PTP time. While I'm an experienced embedded engineer, I am a little bit new to PTP and lower level Ethernet.
I have a few questions about using PTP L2 with the DP83630:
1. Is the DP83630 capable of synchronizing to a master on it's own, with only register transactions, or is there still some MCU development required to handle the Ethernet frames? It's somewhat unclear based on the register and feature descriptions for the part. I knwo fir sure it can capture PTP events, but not if it can perform any actual PTP operations on it's own.
2. In my application, even only a rough timestamp is actually fine. Is there some fairly easy way of simply capturing the more readily available timestamp and using that to set the clock? It seems like I could basically ignore everything past the initial sync message and be fine.I realize this is not a TI PHY question, but is the initial sync message a broadcas?
