Hi Leonard,

If I can get this working I can see a lot of fun in the future learning about GPU and OpenCL.... 

I'm sorry no one seems to have replied to you so far.

Yes, people tried JtR on NVIDIA Jetson TK1 before:

These threads mention some old build issues, etc., but those are
supposed to be fixed or otherwise irrelevant in current bleeding-jumbo
(and yes, it'll be solely OpenCL now, including on NVIDIA, as we've
dropped CUDA support).  So I am referring to the threads not for the way
outdated advice/workarounds given there, but merely to answer your
question.  You'll actually want to use bleeding-jumbo, and just try to
build it in the usual way (e.g., "./configure && make -sj4") without any
tweaks first.

Please just give this a try and report any issues there might be - or
report success even if there are no issues.

Of course, these boards are actually very slow compared to modern large
GPUs that you'd plug into x86 boxes.  But that shouldn't stop you from
having fun.
