Issue with New Jetson Nano - OpenCV Error Prevents Program Execution

I inserted the same SD card into two Jetson Nano devices. One of them is working perfectly fine, but the other one is encountering an OpenCV error and the program won’t run. This problematic Jetson Nano is a new one I purchased last week. Can anyone help me figure out a solution?

Hi,

What’s the JetPack version in use?
Is the device working properly besides the message?
Any log you can provide?

Of course! My Jetpack version is Jetpack 4.6.4 [L4T 32.7.4], and the error message that occurs when running the code is as follows.

The same code from the identical SD card works properly on one Jetson Nano but throws an error on the other Jetson Nano.

Hi,

Maybe your two Jetson Nano are of different variants (like A02/B01), so there is some difference in their capabilities.
Can you please confirm it?

two jetson nano same model(B01)

Are you also using the same hardware for capturing video? Like the camera module.

8

yes i use four IMX219 camera

Hi,

Then can you get another different SD card for the module that does not work, flash with SDK Manager and try again?

Yes I tried it. It still works on one Jetson Nano, but the same error message as above occurs on the other Jetson Nano.

Then maybe consider RMA.
