Does Tk1 can use Cuda8.0?

I have tried several ways to change my tk1’s cuda from 6.5 to 8.0.
I have download the cuda8.0 toolkits and also reset my filesystem to change cuda version to 8.0.
But I failed, so are there any ways to use CUDA 8.0 in tegra 8.0?

CUDA 6.5 was the last version supporting 32-bit. Sorry, the TK1 cannot use anything newer due to being 32-bit.
