I see, but why boot from SD card, which is slower when there is eMMC? Anyways, I flashed it successfully. But now I have no clue as to how to enable CUDA.
I want to do some image processing with OpenCV/CUDA. What I tried is to compile opencv with USE_CUDA=ON flage set in cmake. Then I tested to see if I an use the gpu with opencv. But can't, and get 0 when I call gpu::getCudaEnabledDeviceCount(). This clearly indiacates that cuda is not installed. So how do I install CUDA?
