I won’t be able to answer, but a lot of this likely depends on which carrier board you use. Some questions to get started:

  • Is this a Nano dev kit? Or is this some third party device?
  • Was all of the involved software installed via the SDK Manager (or part of the SD card)?
  • What is the release you see with “`head -n 1 /etc/nv_tegra_release”?
  • Is the kernel or device tree modified in any way?
  • What shows up from the command “uname -r”?

cd /opt/nvidia/jetson-io first

That file with the current release should probably work. Someone else would have to help answer why it causes shutdown. One possibility I can think of is that if for some reason power requirements go up momentarily, then maybe the power supply is insufficient (but I doubt that is the cause; however, Jetsons are sensitive to power supply regulation, so this is a possibility).
