EMAC LL Descriptors

Postby cbrieske » Tue Sep 24, 2019 7:53 am

I have a few questions related to PTP (IEEE1588) support on the EMAC.

According to the technical reference manual, TDES6 & TDES7 are updated with the timestamp captured for the corresponding transmit frame. What is not clear, is where this timestamp is sourced from.

Is anyone able to shed any light on what timer might be used for this timestamp?

Hello, could you finally found the way to implement PTP on ESP32?
