Linux/AM5706: Multiple instances of PTP OC

Part Number:AM5706

Tool/software: Linux

Hi:

     I have a custom AM5708 based board and Linux SDK 5.02.

We have an ethernet interface on GMAC and 2 interfaces on ICSS2 PRU.  There will be scenarios where we have PTP OC instances on both GMAC and ICSS (i.e. different master clocks).

• How does Linux decide which one is the best one?
• Is there any way of forcing Linux clock to use one of the two available clocks?

Regards
