It boots and runs fine (using the standard Linux kernel distributed with L4T). We’re not using the standard Ubuntu-based distribution - we’re using a custom distribution built using internal tools.
The goal of this (which has worked out quite well) is to build small rootfs images we can build into a squashfs and use with A/B updates (using two APP partitions rather than the one). With control over all the package versions we can better control updates, and can easily get a <100MiB rootfs to make over-the-air updates easier.
We’re happy to open-source this system if it would be of use to someone else.
@kayccc is it possible for us to get access to the source for the nvidia-drivers package and then we can compile ourselves. I would guess we need to sign an NDA of some desciption?
If this isn’t possible, could we get someone to compile the drivers with a different toolchain, such as using musl.cc rather than Linaro?
