Hi all,

I am using Nvidia Drive AGX with one camera ar0231-rccb-bae-sf3324 which is connected to channel A.

I want to run ./sample_drivenet & ./sample_light_classifier together using a Single camera.

When I run them individually it is working fine but when I run both at once I could notice the one which I run first is getting executed but the other one doesn’t.

I get the following error:

Driveworks exception thrown: DW_SAL_CANNOT_CREATE_SENSOR: CameraGMSL: cannot connect to camera.

Is it possible to run Multiple different samples using input from a single camera.
Kindly clarify.

Thanks

Dear @s-s.radeshwar,
On same Tegra it is not possible to share single camera by two processes. But You may use --slave=1 on Tegra B to access camera data from Tegra A.
