Jetosn Orin Nano does not detect display after boot

Autonomous Machines Jetson & Embedded Systems Jetson Orin Nano

I currently use Jetson Orin Nano with jetpack Version: 6.0-b52. Before a recent reboot, I could use the system normally and could shut down or boot up without any issues. However, after the latest reboot, I only see the “boot options” screen, following which my display reports no video signal.

I can ssh the device and able to access the device.

I tried to relate my issue with this: Jetson Orin Display Issue After Reboot but could not succeed.

Can anyone help me to resolve the issue? Thanks in advance.

Please elaborate more about this.
Have you checked stuff like lsmod and Xorg log?

Hi,

You mean the display was working properly before, but suddenly went off?
Your Xorg server just started up and shut down immediately, and I feel like maybe some permission stuff in your system is messed up.
What if you manually run startx again?

Yes till yesterday display was working fine. I just shut the device and took out the power adapter. When I again powered on the device, It started normally with the initial boot log on the display, and after that display screen went black, and then the “no video signal” message came up.

Now also when I reboot the device same thing continues.

Through the SSH terminal, I did the following as you mentioned.

Please see if re-flashing the device fixes it.

@DaveYYY Thanks for your help. But Already two weeks back I faced some OS error issues and I reflashed the device. Is there any other way? Because every time reflashing can not be a solution. It took a lot of time to reflash things.

9

Using the SD card image should be a fast way.
As long as you are still able to boot up, there is no issue with the bootloader, so you don’t need to use SDK Manager to do a whole re-flash.

10

My jetpack image version is this Version: 6.0-b52 and as per my little knowledge, we can not flash the latest jetpack through an SD card. right ?

11

It’s definitely possible as your device is already able to boot up with JetPack 6.

Okay, You mean I should use this method to reflash the image:https://developer.nvidia.com/embedded/learn/get-started-jetson-orin-nano-devkit#write

??

13

YES, exactly.
Just make sure you are flashing the JetPack 6 image.

14

Okay, I will do that but while flashing, I hope I will not lose my other components like cuda, cuda toolkit, deepstream, etc. ?

15

Sure.
They are all pre-installed.
