I have issues with the camera and the sense hat. Not quite sure if they are related.
While trying to DeviceRead["RaspiCam"] I don't get any errors, but the connection with the camera drops and I have to run DeviceOpen["RaspiCam"] again to establish the connection. Running raspistill works fine, so I know the camera is functioning.
Also, if I use Run["raspistill etc...] followed by Import[%] it also works.
On the hat, however, I tried to DeviceOpen["SenseHAT"] I get the error DeviceOpen::mraaInitFailure
Failed to Initialize MRAA Library.
Again, if I run a simple python script the hat works just fine, so I also know it not malfunctioning.
A couple of things that may , or may not be related to this: I had to increase the GPU memory to use my NoIR camera to work. I read someone's post about a Package Raspicam.m, under WolframEngine/Devices/ but it is not present in my installation.
The post was not very clear, so I'm not sure if they wrote it themselves.
I ran PacletInformation["MRAALink"] just in case it helped:

Thank you for your help. Please let me know if I can provide more information
