The Sensor Enumeration sample is a minimal sample using the sensor abstraction layer to enumerate all available sensors drivers in SDK.
The command line for the Sensor Enumeration sample, sample_sensors_info, is:
./sample_sensors_info
On execution, the sample outputs a list of sensors in the following format:

The list of available sensors is grouped by the underlying platform (Linux or NVIDIA DRIVE™ AGX) and on the sensor drivers currently available/implemented in NVIDIA® DriveWorks. A list indicates the name of the sensor and the underlying protocol, as well as a set of string-based key-value pairs that you can pass to a sensor as additional arguments.
In the example above, there is a sensor camera.gmsl available that expects as a parameter the camera-group, which can be any value from the set {a,b,c,d}, a number of cameras available at this port (i.e., 1, 2, 3 or 4), and the camera type (i.e., ar0231-rccb-bae-sf3324 or ar0231-rccb-bae-sf3325).
