Hello,

I have 3 drones setup with what is essentially the flight deck setup with a front stereo and tracking camera and a voxl2. The voxl 2's have been replaced from their original and the ones we received are on SDK 1.5.0, in this version there is no option 11 for the voxl-configure-cameras

Available camera config IDs are as follows:

22 - M0173 Seeker V5+ dual AR0144
26 - M0173 Starling 2 IMX412 + dual AR0144
27 - M0173 Starling 2 PMD IMX412 triple AR0144
28 - M0173 Starling 2 Max dual IMX412  + dual AR0144
29 - M0173 Starling 2 Max PMD + dual IMX412  + dual AR0144
30 - M0173 Starling 2 Prototype dual PMD + dual IMX412  + dual AR0144
36 - M0173 Seeker V5+ IMX412 + dual AR0144
37 - M0173 Seeker V5+ IMX412 + dual AR0144 + Boson
46 - M0173 Seeker V5+ IMX664 + dual AR0144
47 - M0173 Seeker V5+ IMX664 + dual AR0144 + Boson
 C - use user-defined custom camera config in
     (/data/modalai/custom_camera_config.txt)
 q - Quit The Wizard

selection:

One of the drones is on sdk 1.4.5 and has had no issues and I can configure option 11. I have copied all the same bins in /usr/lib/camera/ and am using the same voxl-camera-server.conf. 

voxl-camera-server -l only shows 1 camera and it is only 1 of the stereo cameras and the voxl-camera-server does not start any of the cameras

@mkriesel You'll need to re-flash the SDK and select the correct kernel option that supports C11.

When running `./install.sh` you'll see the following options:

```
Would you like to continue with SDK install?
1) Yes, with questions along the way to configure VOXL 2
2) Yes, just update SDK keeping the same SKU configuration
3) No
```

Select, option 1, and you'll get the option to choose which kernel to flash

```
Detected: M0054-1 (QRB5165M)
Detected: Config 1 w/ M0173 Breakout Board (Starling 2 Max, Starling 2, FPV V5)

=======================================================================================================
In order to support all of VOXL's camera configurations, specific drones require differing kernel images.
Please select your drone hardware to proceed with flashing the appropriate kernel image.
=======================================================================================================

PLEASE SELECT WHICH KERNEL TO FLASH
0. M0054-1 -> QRB5165M, Starling (D0005), Sentinel (D0006), FPV V4 (D0008), D0010, PX4 Dev Kit (D0011)
1. M0054-1 -> QRB5165M w/ M0173 Camera Breakout Board, Starling 2 Max (D0012), Starling 2 (D0014), FPV V5 (D0008/D0019/D0020)

Select your choice from the options above
or press [Enter] to continue with current config: 
```

For your use case, you'll want to select option 0 as you are not using an M0173 camera breakout board and the C11 camera config is inherited from the sentinel (D0006) platform.
