AM2632: PRP Ethernet

D Bennett
Prodigy 10 points
Part Number: AM2632
Other Parts Discussed in Thread: AM3356, AM3357, AM3358, AM3359, AM4376, AM4377, AM4378, AM4379, AM5716, AM5718, AM5726, AM5728, AM5746, AM5748, AM5749, AM6548, AMIC110

Does the PRU-ICSS on the AM2632 support PRP ethernet mode?

I see PRP support for other Sitara processors with PRU-ICSS, but not on the AM263x specifically.

If not, would a software-only solution be possible to implement PRP on the AM2632?

    Could you please share the end use case details?

    It could be possible but we have no plans to implement it, it would be upon your digression to implement it.

    I am selecting a processor for an embedded engine controller that will require PRP ethernet communications.
    Two physical ethernet connections with the same IP and MAC address (per PRP requirements). Speed is 10/100 (Gbit not required). Data rate is low (less than 100kb/sec)
    TI shows Sitara processors with PRU-ICSS software for HSR/PRP support for the following:

    Will PRP mode also be possible on the Sitara AM263x processors?

    Hi Bennett,

    Since the data rate is quite low, it should be possible to implement on R5F core also.

    We have taken it in our CCB. We will internally discuss it. I will not be able to comment on availability now
