From the Software Roadmap post mentions the following:
NVIDIA plans to offer greater flexibility to customers for selection of Linux kernel versions and third-party Linux distributions on Jetson by increasingly upstreaming Jetson support to the Linux kernel and by collaborating with the Jetson ecosystem. We plan to provide a developer preview of this flexibility in 2022.
Has anyone successfully installed a third-party Linux distribution on their TX1, such as Fedora or Debian, running a recent kernel with the accompanying toolchain?
