Hello,

I'm using the Connectivity Processor (Arm + EMAC+ LWIP+ptpd) to sync PTP (1588v2) on my Master Clock, all is ok.

But I don't find how to access to the PTP date from the C2000 DSPs, it seems to be only accessible on the Connectivity Manager (Arm processor) throught EMAC registers.

How to access PTP date on C2000 ?

Thanks,

regards,

Christophe

The Ethernet peripheral is only accessible from the Connectivity Manager (CM ) core. You will have to read the EMAC registers and then use IPC to transfer this data to the C28x core.

There are few examples provided in C2000Ware to demonstrate the IPC functionality.
