I run sample_lane_detection and sample_drivenet among driveworks samples in drive px2 with gmsl camera.
The camera type is ar0231-rccb-bae-sf3324 and it is two.
I connected the camera to the 0,1 index of A group and successfully executed sample_drivenetNcamera and sample_camera_multiple_gmsl.
However, it was not possible to execute sample_lane_detection and sample_drivenet with each camera.
The command is:
-./sample_lane_detection --input-type = camera --camera-index = 0
-./sample_drivenet --input-type = camera --camera-index = 1
Error is as follows.
nvidia@tegra-ubuntu:/usr/local/driveworks/bin$ ./sample_drivenet --input-type=camera --camera-index=1

The same error occurs when changing the camera index.
However, if the camera is connected to A group 0 index and B group 0 index, it works well.
I refer to https://docs.nvidia.com/drive/active/184.108.40.206L/nvvib_docs/index.html#page/NVIDIA%20DRIVE%20Linux%20SDK%20Development%20Guide%2FConfiguration%2Fcamera_setup_dpx.html%23wwpID0E0YD0HA , 2 cameras are connected to A group 0 and 1 index. (A group 0,1,2,3 order)
I would like to know in what order to connect the camera to drive px2.
