Updating kernel from 4.9.253?

[akielaries]

I am using your base 20.04 image and notice the kernel was on an old version still. Is it possible to upgrade the kernel on your image or will this break some existing compatibility?

I am trying to install the CUDA toolchain but had seen the warning in the README that v11 and beyond are not compatible with the Jetson's hardware, what version and kernel driver should we target for this image?

[Qengineering]

Updating the kernel is very risk full. You can easily end up with conflicting dependencies. See https://github.com/Qengineering/Jetson-Nano-image/issues/32 Perhaps in the end, you may succeed. However I would strongly recommend not to do so. Besides, the CUDA tool chain is already installed as you can see below.

Ah interesting, I had done a fresh install of the base image but noticed none of the CUDA toolkit was included in image. Is the base CUDA toolchain (not TensorFlow or OpenCV related libs) not included in the base installation?

[akielaries]

Let me try a fresh installation once more and list what dpkg is aware of

When I was trying to do my own installation of a more recent version of CUDA and its driver it had bricked the initial installation from the image. Reinstall worked and was able to have the toolchain all present
