Cuda Cross-compile sample for TX2 - Error Code "no kernel image is available for execution on the device"

[marc.armstrong]

When I cross-compile the vectorAdd sample, and run on my Jetson TX2, I get the error
“no kernel image is available for execution on the device”.

I have cuda 10.2 installed on my ubuntu 18.4 PC, and I build the vectorAdd sample by executing
sudo make TARGET_ARCH=aarch64
Then when I deploy and run on my Jetson TX2, I get the above error.

Both ubuntu PC and Jetson TX2 have CUDA 10.2 installed using the SDK Manager - jetpack 4.6.1.

I can compile and run the sample on the Jetson TX2 but something is wrong with the cross-compilation.

For info, I can build and run deviceQuery, which outputs the following

Can someone help please? Thanks.
