Jetson orin nx Black screen caused by insufficient root directory space

Phenomenon: Unable to enter the interface after booting, unable to enter the command line locally
Phenomenon: The root directory space is full (the root cause is that the virtual memory is set too large and occupied)
I don’t want to re-flash the system, there are many important things in it. In addition, the motherboard has not been configured with ssh before, and the terminal that appears when connected to the computer serial port is a black screen, and there is no display when input. In addition, I tried to use a USB disk as a boot disk to enter the system but failed, because when entering the interface of the boot disk execution, my mouse and keyboard were unusable. In addition, trying to press F10 to enter the bios also failed, and the screen was completely black. What should I do?

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

Hi,

One question to reconfirm:

  • Have you tried connect to the pc with flashing Cable (Type-C to Type-A). And use minicom or picocom to access device?

Thanks
