Questions from Alex O, April'2023:
 
(1) Thank you.  I am attempting to install the tools now.  Two issues present themselves
First, I followed your link under “Additional Resources” and tried to download the Teaching Materials, but I got the same form? 
Do I need to fill out a separate authorization?
Answer>>>Yes. For EdgeAI you request NC-SDK-AC and Teaching Materials separately

 
(2) There seems to be some problem with the kernel drivers in my Beagleboard.   All deployed utilities give this uiNumValidDevices > 0 error. 
Answer>>>That’s not Imagination. Please go to the support area on BeagleBoard.ORG
I cannot figure out how to update my PowerVR drivers on my BeagleBoard AI64
Answer>>>There’s advice on Beagle firmware updates on their site.
Go to:  https:// beagleboard. org/ update-ai64 [link now broken]

Program output below of where I am at.

!!! Note that this is NOT my current kernel, thus I assume I need to recompile this kernel module – but I cannot find it!
