voxl-cam camera-server crash

patrickpoirier

Hello,
I just received the unit and after powering it I could connect to the GUI and see different cameras and point cloud.

After reboot it appears the camera server do not restart
voxl-camera-server | Enabled | Not Running |

When I launch manually , I get

voxl-camera-server
WARNING Failed to set priority, errno = 1
This may be because the FIFO scheduler is not available when running in a console.
It should work properly when run as a systemd background process on boot.
WARNING: failed to set scheduler

Update
After a few hours sitting on bench it could make it restart
After 20 minutes I launched a reboot and it could not restart camera server

The camera is cooled by a fan and temperature is about 35degs c

Hi @patrickpoirier ,

To make sure we're understanding, the hardware on a bench will work at first, but over time (20+ minutes) you are consistently having a failure, but leaving the unit off after it fails for some time, the issue then goes away?

(edit: saw this is a VOXL-CAM, disregard earlier query about HW).

@modaltb
I sent it for repair
You fond an issue with bad connexion on camera
I received it back
It is working OK

BUT
I have an other issue regarding connecting to ArduPilot

It seems it is having issue with MavLink Message :

voxl-mavlink-server[3036]: ERROR message magic number wrong #284
And it seems to reconnect under a different ID

Do you have a clue?
Do you want me to open a new issue so we can follow more efficiently ?

Regards
