CUDA newbie here. I just received my Jetson TK1 and I was trying to run the examples from the NVIDIA_CUDA-6.5_Samples folder but all the samples return the same error:
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL
I used the filesystem provided with the board, installed the NVIDIA drivers from the NVIDIA-INSTALLER folder, performed an apt-get update, installed the CUDA-SDK 6.5 from the Jetson TK1 support page and compiled the samples with make. Further apt-get update or upgrade didn’t solve the problem. I tried “sudo apt-get install cuda-driver-dev-6-5” but it says I already have the newest drivers:

cuda-driver-dev-6-5 is already the newest version.
cuda-driver-dev-6-5 set to manually installed.
