Camera config for M00015 stereo camera only

KnightHawk06

Hello, how can I configure for just the M00015 stereo camera? I don't see that as an option and I tried creating a custom config but I get an error on that too.

https://docs.modalai.com/voxl2-camera-configs/#c-10-front-stereo-only-ov7251

voxl2:~$ voxl-configure-cameras

Available camera config IDs are as follows:

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 Stalker V5+ IMX412 + dual AR0144
37 - M0173 Stalker V5+ IMX412 + dual AR0144 + Boson
46 - M0173 Stalker V5+ IMX664 + dual AR0144
47 - M0173 Stalker V5+ IMX664 + dual AR0144 + Boson

@KnightHawk06 With VOXL 2 different kernels enable different camera configurations. You'll want to flash the kernel that supports camera configs 1-25,

I recommend downloading the latest SDK from downloads.modalai.com, running ./install.sh and when asked the following:

Detected OS: Linux
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
1. M0054-1 -> QRB5165M, Starling (D0005), Sentinel (D0006), FPV V4 (D0008), D0010, PX4 Dev Kit (D0011)
2. M0054-1 -> QRB5165M w/ M0173 Camera Breakout Board, Starling 2 Max (D0012), Starling 2 (D0014), FPV V5 (D0008)

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

Choose option 1 for M0054-1 -> QRB5165M, Starling (D0005), Sentinel (D0006), FPV V4 (D0008), D0010, PX4 Dev Kit (D0011)

@tom I'm trying to flash the same version of firmware that is on the board now but with the different camera configuration but the install.sh script never progresses? It's been ~ 30 minutes.

Running in Interactive mode.

Flashing the following System Image:

Please power off your VOXL, connect via USB,
then power on VOXL. We will keep searching for
an ADB or Fastboot device over USB

[WARNING] This system image flash is intended only for the following

@KnightHawk06 I had to update the fastboot permissions and reboot the device.

sudo gedit /etc/udev/rules.d/51-modalai.rules
