Probably right.

There's a lesson here that you should be putting console output
either directly into your e-mail (trimmed to important points).
Putting the output into an image makes it slow to read and tedious
to quote.

 From what I can tell, you aren't running on an image that otherwise
supports GPU or VPU acceleration. That's a pre-requisite for this,
and I recommend using fsl-image-gui or some other known good
starting point.

Also note that we sent these patches not to imply that they're
fully functional, but to allow others to have a working example
for exploring the code.
