I am trying to run the simpleCUFFT but I get this error:

/usr/local/cuda-11.3/samples/7_CUDALibraries/simpleCUFFT$ ./simpleCUFFT
[simpleCUFFT] is starting…
CUDA error at …/…/common/inc/helper_cuda.h:779 code=999(cudaErrorUnknown) “cudaGetDeviceCount(&device_count)”

From deviceQuery I get

usr/local/cuda-11.3/samples/1_Utilities/deviceQuery$ ./deviceQuery
./deviceQuery Starting…

CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 999
→ unknown error
Result = FAIL


If you want to use CUDA 11, please reflash your device with JetPack 5.
There are some dependencies between GPU driver and libraries, r35 is required for the CUDA 11.
