-> Any road map for Powerlink protocol for Am6421?

-> As per my findings current PRU-ICSS Powerlink firmware for other Sitara series support for MII (Full duplex & Half duplex) not RGMII ? Rational behind to ask that we want to use COL and CRS line for other purpose that only possible with RGMII. As RGMII don't require this line for half duplex communication.

Hi Nikhil,

There is no update on the Powerlink Roadmap. Recommendation is to work with PORTG | Partner profile | TI.com.

Your understanding is correct, the current firmware has support for MII mode only

Prajith

Prajith Jayarajan : Just note ... As per my findings current Ti Am64 EVM hardware not compatible for Powerlink as it require Half duplex transmission mode (Specification document - EPSG_301_V-1-5-1_DS-c710608e , section 3 physical layer , page 35) . Half duplex transmission mode requires COL & CRS lines which is not utilized.
