Hi,

For nvgpu error, it requires to know what kind of application is running and causing this problem. Are you able to provide that?

open/close camera。

Please share your full application to us so that we can reproduce. It is not possible to just know what is going on with one screenshot of your code.

Hi wayneWWW, my application is Encrypted. Can you tell me which file report this err??

nvgpu driver is public kernel source code.
