Hi:

Could you please list the content of your /data/misc/camera directory? I am wondering if the process of generating that file was interrupted and now it doesn't attempt to generate it anymore.

If there is anything in the /data/misc/camera directory I would move it to another temp directory - say /data/misc/camera/temp and try running the app again.

Also as a quick experiment, I would put in just the TOF camera, remove other cameras and run the app again to see if it helps.

That error happens when we dont set up TOF_CAM_ID environment variable or it is setup incorrectly. The environment variable is set by running the voxl-configure-cameras script. If you havent run the script, could you please try running it. To verify it quickly you can try to directly modify the TOF_CAM_ID environment variable.

On the voxl run:

export TOF_CAM_ID=0

and try running the app again.
