Differences in NETCP between K2H and K2L?

Alan Morales

Do the K2H and K2L have different versions of the Network Coprocessor (NETCP) peripheral and underlying Packet Accelerator (PA), Security Accelerator (SA), gigabit Ethernet switch (GbE)?

Looking at the data sheets available on the product pages on the TI site, it seems to indicate that they do have different versions of the NETCP.  The K2H page points to older (Keystone 1?) documents for NETCP, PA, SA, etc.  The K2L page has links to documents for newer versions of  NETCP, PA2, SA2, etc.  These documents also only mention K2L and K2E processors and do not mention K2H.

Based on this, is it it accurate to say that the K2L has a newer NETCP subsystem than K2H, even though they are both Keystone 2 chips?

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues). Be sure to search those for helpful information and to browse for the questions others may have asked on similar topics (e2e.ti.com). Please read all the links below my signature.

    We will get back to you on the above query shortly. Thank you for your patience.

    Thank you.

    Note: We strongly recommend you to create new e2e thread for your queries instead of following up on an old/closed e2e thread, new threads gets more attention than old threads and can provide link of old threads or information on the new post for clarity and faster response.

    Dear Alan,
    As far as I know, the same NETCP (PA and SA too) module is used in K2L SoC too.
    10GbE support is not available in K2L.

    Let me check with internal team too.

    Hi
    Yes the version of NETCP on Keystone 1 family and K2H/K2K is older than what is available on K2E and K2L family and hence the documentation makes the distinction via SA vs SA2 terminology.

    OK thank you, that's what we suspected but just wanted to confirm.
