Hello,
Have you taken a look at the SDK for the KW41Z? All the available drivers and files are available there. You can download them at the MCUXpresso SDK Builder page.
Also, you can check the Kinetis Thread Stack Demo Applications User's Guide, under the docs folder, there you will be able to find how to use it with some operative systems, nonetheless, I'm not quite sure if it will work for you.
Also, please take into account that the PQ2FADS-VR has limited support.
Regards,
Estephania
