Starling drone shut down mid flight

[Alex Kushleyev]

@Shivam-Sehgal , sorry, can we please take one step back and clarify something..

Does the VOXL2 board now boot with all the cameras plugged into the original configuration?

Also, when you say After this I manually restarted the voxl-camera-server and the connection broke after the output below. -- which connection are you referring to?

If you are able to connect all cameras to their original slots, but something is still not working, i suggest that you test with only one camera enabled at a time and figure out if there is still one camera that is not working.

@Alex-Kushleyev I hope this clears somethings out, its confusing for me too.

no it does not boot now with all the camera's plugged in original physical connections.
It was not about the physical connections, but when the camera service started then the connection broke.

First I shifted the physical connections of the camera's as mentioned above, after which I could boot but the hires and tracking camera did not work or start. (https://forum.modalai.com/post/19383)

Then restored the original physical connnections, set the voxl-configure-camera to it original configuration it's shipped with and then restarted the voxl-camera-server.

When I started the service this the output of it, after this output the adb and ssh connection broke and I was unable to connection to the voxl2 board.

@Alex-Kushleyev I was able to point out maybe it's the hires camera that's the issue. I don't know why but I was singly able to run all other camera's but not the hires camera.

What defect should I look for?

Also, while doing all that I broke the tracking camera's connector and the 2 in 1 camera boards. I will be ordering those. How can I remove the 2 in 1 camera board from the voxl2 board?

[Shivam Sehgal]

@Alex-Kushleyev any update?
How can can I remove the 2 in 1 camera board?

[Alex Kushleyev]

@Shivam-Sehgal , sorry for the delay!

Can you please contact our RMA department and send them the pictures of the current state of the board and camera adapter interposers. Our production team can evaluate the pictures. On some products the interposer boards may be glued in place for robustness, so they can suggest best way to handle it.

In general, here is a diagram from the Hirose's product manual that shows how typically you should remove these connnectors:

@Alex-Kushleyev Yes Alex, it's glued to the board. Sorry, how can I connect with RMA department?

@Alex-Kushleyev It's a form to send my drone for repair, can't I repair it myself? I have already ordered all the parts required. I just need to understand how to remove the glue.

[tom]

@Shivam-Sehgal I will see if a member from our production team can chime in here

[Jeremy Schmidt]

@Shivam-Sehgal
The glue is an easy to remove RTV silicone adhesive. If you follow the instructions posted by Alex, you should be successful. I've done this myself a couple of times.

After removing you will need to clean away as much of the remaining glue on the voxl2 as possible before installing the new adapter board. You don't necessarily need to apply glue when installing the new board, but we find it helps with keeping the adapter from accidentally teetering at the hirose connector.

Please let me know if you need further help with this matter

[Shivam Sehgal]

@Jeremy-Schmidt So I don't need heat or any special tool for it I can directly remove by hand?

[Shivam Sehgal]

@tom I was able to get the camera board out thank you but ...

When I again add the 2 new camera boards with out the camera's attached it works I can adb into the board, but as soon as any camera is added I cannot adb into the board.

I am using 2 new boards and 2 new camera's tracking and hires it seems like the issue is something else what can I do?

[tom]

@Shivam-Sehgal Double check the pinouts to ensure the sensors aren't being plugged in backwards, that is the most likely cause of a board not booting

[Shivam Sehgal]

@tom thanks I had opened the board so I did not notice it, only if I had assemble I would have noticed it.
Thank you so much it worked!

[Shivam Sehgal]

@tom @Alex-Kushleyev
I corrected everything and it seemed to work for a minute there then again adb connection broke.

I disconnect the cameras and I am able to adb but with the cameras it does work for like 10 seconds and then the connection breaks.

[Alex Kushleyev]

@Shivam-Sehgal , does it look like the board is rebooting after 10 seconds of running with cameras enabled? also, what if you ssh into the board, does the SSH connection stay alive when the cameras are connecting?

Also, how are you powering the drone for this test - battery or power supply?
