Sentinel (VOXL2) not booting/not flashing
-
Hello,
Our Sentinel drone was working yesterday when we left work, but this morning it wouldn't boot: no Wi-Fi network, no devices listed with
adb devices
, lights on the ESC don't stay on after the first seconds, and no lights on the GPS sensor.
The LEDs on the VOXL 2 main board and 5G board all seem to be on their normal state.I think it is important to say that, at this point,
lsusb
was outputting:Bus 004 Device 004: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)
, and not something like
Bus 004 Device 033: ID 05c6:901d Qualcomm, Inc. KONA-QRD _SN:FDF5950D
as we were expecting from seeing this post. We found theQDL mode
part to be a little bit odd, but please confirm if this is normal for a Sentinel drone that was unaltered (HW and SW).After discovering this, we removed the VOXL2 board from the drone and tested
fastboot
.
For this, we carefully followed all the steps on this tutorial, but no devices were listed by thefastboot devices
command.Since this was also not working, we followed the VOXL 2 QDL Guide to try and flash the VOXL2 QDL Image 14.1a_1.1.2. What we got was:

Or sometimes, after this, the command would run instantly but with no console output.
We are having a lot of difficulties figuring out what went wrong. Hope you can help us.
-
@Andre-Moura Sorry to hear you're having troubles. Thank you for posting the info and what you've already tried.
How was the drone powered? By a battery or power supply? We have seen a few issues with the power supply. Main concern is arming the drone with it.
For the drone to get into QDL mode, the Voxl somehow got bricked or a power issue. Was any software running before de-powering the drone?
-
@Adrian-Hidalgo We have been powering the drone only with batteries, never used an external power supply.
On our last tests, we were using only the services already available on the VOXL 2. With a minor modification to the voxl-tag-detector service, to use the front stereo pair, instead of the tracking camera. -
@Andre-Moura ok, thanks. Are the LED's solid or are they flashing on and off every four or five seconds?
Another method that would be worth trying would be to plug both power and usb(in that order), run the install script and hold down the SW1 switch for 25 seconds(should see the LED's flash signifying reboot) -
@Adrian-Hidalgo The LEDs are always solid green.
Did what you suggested, but the install script didn't work. Got this:Installer Version: 0.8 Image Version: 1.5.5 [ERROR] No device found in adb or fastboot [INFO] Failed to put device in fastboot mode, exiting
-
@Andre-Moura Did you accidentally flip the QDL switch on either the VOXL2 or an add-on board?
-
@tom Definitely not on the VOXL 2, I checked it beacause of the output of
lsusb
that I showed previously.
Add-on board? Is there another switch on the 5G board or one of the Sentinel boards? I think that is a very unlikely scenario, the drone was working one day and the next it wasn't, without any changes. -
@Andre-Moura Some of our add-on boards in the past had the same switch on it but it would be obvious.
If it's still booting into QDL mode, then I would try the QDL tool again. Looking at the output you posted it doesn't look like it ran successfully. I would try again when you get a chance, maybe with another cable or USB port.
-
@tom I tried it extensively with different cables/ports/computers during today with no result.
-
@Andre-Moura Okay, then I'd recommend an RMA: https://www.modalai.com/pages/rma
-
@tom Hello,
My issue is very similar to this, getting the same output as above when I perform the 'initiate flash' sequence.
My drone was working fine and now when I try to use it again it's having the same issue where 'adb' doesn't detect it. Only for me it wasn't a next day issue, I haven't used my Sentinel for a few months as I was caught up with other projects. Now al of a sudden it won't connect at all.Just wanted to know how this was resolved? Want to avoid the RMA if possible as it will be difficult for us.
Everything suggested so far in this post has been attempted, still facing the issue. Also the errors are exactly similar to what @Andre-Moura faced. Only using batteries provided by ModalAI as well.Cheers,
Joshua -
-
@JoshRebello If you run
lsusb
orsudo dmesg -wH
on your host PC do you see the device enumerating when plugged in? -
@Andre-Moura Hi Andre,
Just reaching out in case you get this. I'm currently facing the exact same issue you had with your sentinel, the same as in this thread. Done all the checks similar to what was posted in this thread got the exact same results as you as well - so I'm assuming it is the same issue that you had.
I've been asked to do an RMA but I wanted to check if there was anything else I can do before an RMA as shipping back to the US will be an issue for my company. How did you get your issue resolved in the end? Via RMA or did you find a solution?
Hoping to hear from you.
Kind regards,
Joshua Rebello. -
@JoshRebello We solved this issue with an RMA, motherboard was damaged according to the RMA report.

@Andre-Moura Hi Andre,
Thanks for the quick response on this, really appreciate it!Seems like it's mostly going to be an RMA for me as well, letting the company know is going to be tough.
By any chance, do you remember the costs your entire RMA process came to? Shipping and back, just trying to get as much info as I can to submit to my company.Thanks in advance!
Kind regards,

@JoshRebello I'm sorry, I don't remember the value.
