I have identified the following</p>
<ol>
<li>
<p dir="auto">I dont think its a hardware issue as i tried connecting my board with a brand new camera without any flex cable extension and the issue persists. I am also facing this problem with 3 other boards</p>
</li>
<li>
<p dir="auto">When the camera server is started, i get a few seconds worth of frames and then the crash happens. If I have the voxl portal open with the option to view the hires selected and then start the camera server i can see the camera frames for a few seconds and then it freezes. While the camera server is frozen, I see the stream from the tracking and stereo seem fine for a few more seconds after which all camera streams stop and the camera server crashes</p>
</li>
<li>
<p dir="auto">The error seen is -19 which can be seen by starting the camera server using -d 0 parameter and when checking the journalctl for the camera server i see the following<br />
Sep 05 22:24:10 voxl6 bash[2117]: Segmentation fault:<br />
Sep 05 22:24:10 voxl6 bash[2117]: Fault thread: CAM_METADATA(tid: 3214)<br />
Sep 05 22:24:10 voxl6 bash[2117]: Fault address: 0x581<br />
Sep 05 22:24:10 voxl6 bash[2117]: Unknown reason</p>
</li>
<li>
<p dir="auto">I have also tried updating to the latest firmware v3.8.0-0.7</p>
</li>
<li>
<p dir="auto">I tried multiple resolution configuration (640x480, 1280x720, 1920x1080 and 4000x3000)</p>
</li>
</ol>
<p dir="auto">If anyone can help me out, that would be appreciated</p>
<p dir="auto">Regards<br />
Vivek</p>
