I meant "besides" just TIDL. Also, I've started the README.md at https://github.com/beagleboard/cloud9-examples/tree/master/BeagleBone/AI/c66 . It seems the images have the /usr/share/ti/examples/opencl directory already. Unfortunately, it is owned by root, so you'll need to go into there and run 'sudo make'. It looks like some of the examples use SDL, so you'll want to run 'sudo apt update; sudo apt install libsdl2-dev' first. For the examples that require XDC, I don't have an easy answer today. Here's some quick output: debian@beaglebone:/usr/share/ti/examples/opencl$ cd simple/ debian@beaglebone:/usr/share/ti/examples/opencl/simple$ ls kernel.cl Makefile Makefile.rtos simple simple.cpp simple.o Done! debian@beaglebone:/usr/share/ti/examples/opencl/simple$ cd ../vecadd/ debian@beaglebone:/usr/share/ti/examples/opencl/vecadd$ sudo ./vecadd DEVICE: TI Multicore C66 DSP Offloading vector addition of 8192K elements...
