Sentinel drone randomly reboots

[rohitpillai]

@tom Yep let me test this out and get back to you.

@Jeremy-Schmidt If no other solutions work, I will bring it into the office early next week!

@rohitpillai When you removed the extension cable, were you still plugging the tracking camera into the M0054 board directly?

[rohitpillai]

Yes, I believe so. We plugged it back in exactly how it was when we picked the drone up.

[Dobry Kolacz]

@rohitpillai do you have a spare mcbl-0001 you can try on this setup?

[rohitpillai]

I re-flashed the drone with the new VOXL2 package and it seems to have fixed itself for the time being. I will post in this thread again if the issue springs back up.

[rohitpillai]

Update: We are hitting a roadblock where adb shell is not working and the device is not showing up under adb devices. Could you help us here? We are able to SSH in fine but can't use the cable.

Thanks

@rohitpillai What is the output of lsusb on the host PC with the Sentinel plugged into it via. USB-C?

@tom

This is the lsusb result.
After rebooting many times, it was detected by lsusb. But when we attach the 'VOXL Microhard Modem Add-on with USB Hub', it kept rebooting and didn't work. I think we have to bring them to your office and check it.

@dlee Any sort of reboot loop is likely to be an MCBL-0001 failure

@tom
VOXL Sentinel
This is the reboot loop.

@dlee Yep that looks exactly like what I've seen when the MCBL-0001 from the power module goes bad. Do you have another you could try with? If not, you could try making sure all of it's wires are seated fully into their connectors. Depending on how often / how the cable was unplugged the wires may not be fully seated.

[dlee]

@tom Yep, I have another. What should I do. Check the power cable?

[tom]

@dlee Yeah I would try switching out the drone's MCBL-0001 for the spare that you have to see if it solves the issue.

@tom Thank you. It works well
