Original question:

IWR1642: SDK3.0 Support for IWR1642

IWR1642: Which SDK version should be used for new designs

Part Number: IWR1642
Other Parts Discussed in Thread: IWR1843, IWR6843

Hello!

  • The SDK linked from the IWR1642 product page is the 3.5.0.4 (and the release notes list xWR1642 ES2.0 as supported).


Those posts may be out-dated, so, what SDK should I use now (end of 2021)? And, if both choices are possible, where can I find information about the tradeoffs?


Thank you!

    Hello

    The LTS support for xWR1642 device was brought through SDK version SDK 2.1.0.x  post that SDK version have  demo architecture  changes and  additional device support.

    The drivers stay the same so applications developed on SDK 2.1.0.4  will still compile on higher version of SDK  as long as the release notes mention the support for that device.

    Hope this helps.    We had a top level SDK landing page which has been removed due to  website architecture changes - we will try and bring it back  to capture such information.

    THank you,

    Hello Vaibhav,

    Thank you for your answer! I'm sorry but I'm unfortunately not sure to fully get it.

    Is the use of the LTS of the SDK2 only to support some of the labs that weren't ported to the SDK3 for the IWR1642?

    Here is my situation:

    • What I need is a SDK+demo providing a point cloud according to a given ramps configuration.
    • I would prefer to use the SDK3 for better "future-proofing" (and envisioned future ports to the IWR1843 and IWR6843).

    So, starting with the IWR1642 demo of the SDK3 looks like a natural approach to me (I configure the ramps, get a point cloud, and add my part of processing). But I get the impression from the forum (and  the mere existence of an "LTS") that it is somehow recommended to stay with the SDK2 for IWR1642:

    • Is the SDK2 indeed recommended for IWR1642?
    • If I go the route of SDK3+demo, what sort of problems will I run into?

    Thank you!

    Hi,

    I would recommend that you go with the latest version of SDK 3.5. The Out Of Box Demo for IWR1642 is provided in SDK 3.5, however there is no projectspec for this version, so you would either need to build it directly from src or to create your own .projectspec file by modifying one of the existing ones in the Industrial Toolbox

    Best Regards,
    Alec

    Hello Alec,

    Thank you for your answer and the additional info about the .projectspec!

    Good to know clearly that the SDK3.5 is the way to go with the IWR1642! (or a least one valid way to go).

    Best regards,

    Paul-André
