I have a VOXL2 board running system image 1.4.1 and has voxl-camera-server version 1.3.5. I have the M0025-2 camera.  It is connected to the M0076 Interposer and then connected that to J7 on the VOXL2.  No matter what camera configuration I seem to try, the voxl-camera-server always throws a segmentation fault when it tries to start.  I hope I'm doing something wrong, but I can't rule out bad hardware.  Is there something I'm doing wrong or other troubleshooting to try?

That implies a hardware issue. Are you sure things are connected in the correct direction? Can you share a picture of your setup?

Also, please make sure power is off when changing components

@aharvey have you looked at our [docs](https://docs.modalai.com/voxl2-camera-configs/)?

Here is my setup.  I have read the docs but nothing has helped.  Maybe I have a bad interposer?

I have tried connecting the interposer to J8 and J6 with the same results.

Will be released within a week
In the meantime you will have to use M0084 on J7

@Adrian-Hidalgo 

So unless I update the image to 1.5.3, I need to use "M0084 VOXL 2 Dual Camera Adapter" and NOT "M0076 Interposer"?

@aharvey Yes, that's correct. It'll be available in about a week, what I hear from software

I updated to the beta 1.5.3 image and this camera now works with it on its own.  Thanks!
