I am using LabVIEW 2020 Professional with NI LabVIEW LINX Toolkit instead of the LabVIEW 2020 Community Edition and found some software requirements I did not expect. As can be seeing in the image below if I only install LabVIEW 2020 Processional and try to open a project that included targeting a Raspberry Pi I get an Unsupported Item error.
For this example I used the Simple-Pi-WebVI-WebSockets project by MediaMongrels. Note: This project also requires the WebSockets package available in VIPM.
What I found is that LabVIEW RT 2020 also needed to be installed for the project to successfully open.
This makes sense to be because from what I have read the LINX Toolkit targets the Raspberry Pi like a RT device but I have not found any information on what the minimum software requirements are for a Raspberry Pi project with LINX. I am one who only like to install the minimum software required to make sure I understand why everything is needed so I am wondering if anyone has some additional information on this subject. Maybe all of RT does not need to be installed but just some driver? I assume all of LabVIEW RT is not included with the LabVIEW Community Edition so there is probably some subset of LabVIEW RT that is required.
At the very least maybe this post will help someone else who is starting a Raspberry Pi project with LabVIEW Professional.

I am facing issues in connecting my raspberry pi 3 with LabVIEW 2020 SP1, fulfilled all requirements, by following this tutorials https://www.instructables.com/Getting-Started-With-the-Raspberry-Pi-2-LabVIEW/
linix by digilent/ labview makerhub suppoerted for labview 2020.
rpi is in working condition.
ssh is enabled
but when i tried to connect via

it shows me error
device interrogation failed: unable to connect to target

If you following the instructions that the link you provided then you probably messed something up as those instruction are for LabVIEW 2014 when LINX was not officially part of LabVIEW.
If you are using LabVIEW 2020 SP1 Professional edition then you will need to install LabVIEW 2020 RT and the LINX toolkit from VIPM as I have stated here. I have included images of the correct software version so you can verify you have everything correct. If you installed an older version of LINX it will not work. You will need to uninstall what you added and install the correct version from VIPM.
Confirm that you have installed the correct software and if you still get an error please provide images so we can exactly see what you are referring to.

Were you able to connect to Raspberry pi? What procedure did you use? I am wondering if I follow the video from 2016, install raspbian 2016 and use linx 2020 version target connection, will it work with 2020 sp1 Labview professional version + the RT packages you mentioned?
