I used JetPack 4.2 for the new J121 and R32.1.0.
I see a post for a patch on JetPack 4.2.1 for R32.2.x, but that return a libnvbufsurface.so problem for me (R32.1.0).
So, i try to use this patch from Nano version R32.1.0. without libnvbufsurface.so problem.
But, TX2 and Nano are not sames GPU.
Can you corfirm that’s work (only Cuda depends), or rebuild a release one for TX2?
