Jetson nano shows nothing when booting with graphical.target and no cuda devices are found with deviceQuery

Hi,

I am trying to fix an error with my Jetson nano. I can’t reflash the device because some third-party drivers are installed and I can’t get the driver installation files. I found out that multiuser.target works, but not the graphical.target. Actually it is only important that I can use CUDA for my purposes.
When I run the device query I get the following error.

./deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking) 

cudaDeviceCount returned 999
-> unknown error
Result = FAIL

Attached are two serial dumps. I was able to observe these on various restarts:
serial_dump1.txt (208.5 KB)
serial_dump2.txt (224.6 KB)

I would be very happy about any help,
kind regards

Hi,

Have you applied any changes to the GPU/CUDA driver or libraries?
Does it report error=999 at the clean flashing stage?

Thanks.
