and couldn’t run the tutorial. What can i fix this.

I am using jetson nano package B01.

Thanks.

Which camera are you using?
Are you using Jetpack 4.3?

I am using raspberry pi camera module v2. And yes ı am using jetpack4.3 and also ı would say you are late …sorry but it’s been 16 days. Now I am trying to use JetBot instead of Isaac SDK. Still wondering why i got this error. Also ı understand that it’s about camera but rpi camera module v2 was suitable with jetson?

Thanks for the info. Can you additional provide the output of
v4l2-ctl -D --all?

Like i said before i delete Isaac sdk and install jetBot . So i can’t show the Jetson Nano’s output. But I can print host machine’s output of the code maybe it can help.

Here it is:

v4l2-ctl -D --all

Command ‘v4l2-ctl’ not found, but can be installed with:

sudo apt install v4l-utils

and when then i run the install code. And tried again Here is the “v4l2-ctl -D --all” output:

If I re-install Isaac SDK will it help you ? Or it’s all about camera that chosen. I will energise depends on the reason.

Hi fatih.ozkan,

The sample that you are trying to use is intended for USB camera(v4l2 device). And you are using raspberry pi camera module v2 which is a csi camera. You need to include an appropriate module(sensors:argus_camera) in Isaac sample in BUILD and app.json files and run the application.

Hi @Swapnesh, i am trying the v4l2 sample with Isac SDK 2021 and Jetpack4.5.1 running on AGX Xavier kit. I am getting the same error i.e.
