I have checked the voxl-camera-server and find some problems: Terminal output 1: ``` system-image: 1.5.5-M0054-14.1a-perf kernel: #1 SMP PREEMPT Fri Mar 24 00:48:55 UTC 2023 4.19.125 -------------------------------------------------------------------------------- hw version: M0054 -------------------------------------------------------------------------------- voxl-suite: 0.9.5 -------------------------------------------------------------------------------- voxl2:/$ voxl-inspect-services Service Name | Enabled | Running | CPU Usage --------------------------------------------------------------- docker-autorun | Disabled | Not Running | docker-daemon | Disabled | Not Running | modallink-relink | Disabled | Not Running | voxl-camera-server | Enabled | Running | 0.0 voxl-cpu-monitor | Disabled | Not Running | voxl-dfs-server | Enabled | Running | 0.0 voxl-imu-server | Enabled | Running | 0.0 voxl-mavlink-server | Disabled | Not Running | voxl-modem | Disabled | Not Running | voxl-portal | Enabled | Running | 0.0 voxl-px4-imu-server | Disabled | Not Running | voxl-px4 | Enabled | Running | 0.0 voxl-qvio-server | Disabled | Not Running | voxl-remote-id | Disabled | Not Running | voxl-softap | Disabled | Not Running | voxl-static-ip | Disabled | Not Running | voxl-streamer | Disabled | Not Running | voxl-tag-detector | Disabled | Not Running | voxl-tflite-server | Disabled | Not Running | voxl-time-sync | Disabled | Not Running | voxl-vision-px4 | Disabled | Not Running | voxl-wait-for-fs | Enabled | Completed | voxl2:/$ systemctl status voxl-camera-server ● voxl-camera-server.service - voxl-camera-server Loaded: loaded (/usr/bin/voxl-camera-server; enabled; vendor preset: enabled) Active: failed (Result: signal) since Mon 2023-11-06 08:52:53 UTC; 45s ago Process: 1403 ExecStart=/bin/bash -c /usr/bin/voxl-camera-server (code=killed, Main PID: 1403 (code=killed, signal=ABRT) Nov 06 08:52:17 m0054 systemd[1]: Started voxl-camera-server.

I wonder if the problem happens in voxl-camera-server because from the Terminal output 1 : ``` voxl2:/$ voxl-camera-server ------ voxl-camera-server: Camera server is now running WARNING: Camera stereo recieved much newer master than child (33), discarding child and trying again ``` Is the biggest problem from 'WARNING: Camera stereo recieved much newer master than child (33), discarding child and trying again' or somewhere else?
