For my given application, it is not practical for my case to be running the voxl-tflite-server all the time. I have a python application that needs to perform a lot of inferences only some of the time. My object detectors are in tflite format and currently run on the CPU. I want to use the NPU on the voxl, but don't know where or how to load its delegates. I thought maybe, just maybe the delegates might be in /usr/lib but I cannot get them to load in python (I get undefined symbol errors).

Can someone point me to where I can find the delegate to load in python to use the NPU (on the VOXL2 does using the GPU really get to the NPU) or tell me what I need to do to compile a delegate to use the NPU?

@afdrus instead of rebooting, you can restart the server with: systemctl restart voxl-camera-server

I am having the same problem. I created a the snapshots folder too, and the camera server crashes.

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

@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"?

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

power is off when changing component

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

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?

I have a VOXL2 board running system image 1.4.1 and has voxl-camera-server version 1.3.5. I have the M0062 IMX678 (or is it IMX412?) camera (https://www.modalai.com/products/m0061-2). This is the only camera I have at the moment. I also have M0076 Interposer. I have connected the camera to the interposer with the included J2-J1 extension cable, and then connected that to J7 on the VOXL2.

Whenever I start the voxl-camera-server, it crashes with a segmentation fault (saying "address not mapped"). My voxl-camera-server.conf file only has one camera in it, with type set to "imx214" and id set to 0 (also tried 1-8). I see a green light momentarily turn on when I restart the server, but that's it. From reading through the docs, I'm thinking I may need to update the camera server to 1.4.1? Can anyone point me in the right direction on how to update whatever it is that needs to be updated so I can use the camera modalai sold me?

I'm trying to test and evaluate some tools on a VOXL2 and wanted to see in real time what imagery it's working with and output of the tools. I wanted to setup a remote desktop session on it, but it upon connecting using XRDP, the connection immediately closes. From what I've seen in some logs, it looks like a connection cannot be made to any display, and I suspect it's because there aren't any graphics drivers loaded or an XWindows server can't start. Does anyone have any experience using a desktop session on the VOXL2 who can point me in the right direction to fixing this or have suggestions on what additional packages I can install?
