Could anyone tell me what happen to my orin device and how to fix this problem? Thanks

Dear @McGrady,
I am assuming the target is DRIVE AGX Orin Devkit(P3710). NvRmGpuLibOpen failed, error=14

Can you poweroff and poweron the target and see if it fixes. You may disconnect/reconnect power supply.
We noticed this error earlier when sudo reboot now is fired on target.
If this does not fix the issue, can you check reflashing the target?

Dear SivaRamaKrishnaNV:
Thanks for your reply, I have tried to reboot and power off the device, it doesn’t works, I will try to rtelashing the target device lately.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Is this still an issue to support? Any result can be shared? Thanks
