<![CDATA[Segmentation fault camera server with voxl2 sdk 1.0.0-beta4]]>Hello,
I recently received voxl2 SDK 1.0.0-beta4 along with system image 1.6.2-M0054-14.1a-perf. I installed this system image and voxl suite on my VOXL2 hardware board. My desired camera configuration is hires (imx214) + tracking (ov7251) + TOF. I configured this via voxl-camera-configure 6. After this config I restarted voxl2 and checked if I am having pipes up for all three cameras but they dosent seems to be working. Please find verbose logs below. Also with same hardware connections if I configure one camera at a time or even hires + tof and tof + tracking, they work well but all three cameras together aren't working. Please help

@Eric-Katzfey. I got beta release few days back on request basis. Please help on above problem.

It works well now with above workaround.
Also on seperate I have opened one more ticket regarding voxl-streamer over here, please respond on that as well since it is also related to new beta image.

Not documented at all so absolutely not your fault for following what is on our docs. We may switch it back to the way you have it there but for the time being the workaround is to arrange your cameras as seen in this pic:

Also with this hardware connections I can see C4,C8,C9 camera config work successfully but just not C6.
