Hi guys,
The help was much appreciated. We've managed to break through to the device now!

It appears the problem we were facing was two-fold.

• The tracking camera connection was indeed backwards - We had (wrongly) assumed that the camera should be connected such that the cable is leading out from the device, not inwards.
• We had used 2x extension cables for each of the cameras(stereo, tracking), the device does not boot with any extension cable on the tracking camera. It does boot with 4x extension cables on the stereo cameras though. I am curious if this is to be expected or if our tracking sensor may be faulty?

Many thanks for the quick assistance.

Hi @modaltb ,
Thank you for that insight.

That was indeed our intended use case, given the size of our vehicle, but as we have experienced, image quality does indeed degrade (looking at rqt-image-view) using that many extension cables.

We are currently investigating placement options to see if we can fit the VOXL and sensors such that we can avoid the extensions.

We have also learned about the existence of extension interfaces for MIPI CSI-2 (THine for example provides such a solution). Do you or your team have experience with these solutions?

Hello,

We have recently acquired a VOXL which we are attempting to setup to use collision prevention and VIO features for our Pixhawk 4(running PX4).

We have connected stereo cameras and a tracking camera, as well as WiFi antennas and are currently powering it off a 2S LiPO battery.

Initially we were able to connect via ADB to the VOXL and changed the WiFi mode to station, connected to our WiFi and used opkg update + opkg upgrade to make sure the software was the latest version. We then ran voxl-configure-cameras succesfully.

However after running voxl-configure-vision-px4 and rebooting we are no longer able to communicate with the device. The green LED flashes when we connect power, but no device shows up running adb devices on our dev machine. Connecting it to our Pixhawk 4, we see no MAVLink packages indicating that it is running either.

What steps do you recommend we take from here to troubleshoot?
