Jetson orin nx jetpack missing

exec apt-get upgrade at orin nx
jtop: jetpack not detect/jetpack missing
and usb0/1 not effective,
what should i do next?

Are you using NVIDIA devkit or custom board? I guess it is a custom board.

A custom board cannot work with apt-get upgrade directly because it will install you a BSP for NV devkit. And that will directly lead to some of your hardware not work.

Please go to flash your custom board BSP again.
