Cuda 10.0 installation on Xavier

Hi, we have a xavier board which runs 10.2 cuda, profiling has revealed that the kernel execution time is ~10% longer in it than another board (same hardware) with 10.0 cuda. I am trying to see if I can replace the 10.2 cuda with the older version but I cannot find download of 10.0 cuda for ARM64 in the archive. What is the right way to do this downgrade?

With the caveat that I know nothing about Xavier, my understanding is that Cuda for these devices is supplied via JetPack, rather than downloading the toolkit in the conventional manner.

Here is the JetPack archive page which may have what you’re looking for:

Actually by changing the sourcelist to one corresponding to an earlier jetpack, I could downgrade the cuda version by using just apt
