Starling drone shut down mid flight
-
I attempted to connect to the drone, but initially, the connection failed. After some time, I was able to establish the connection. While flying the Starling drone in offboard mode, it suddenly shut down mid-flight and fell to the ground. Following the incident, I was unable to connect to the drone using ADB or Wi-Fi for some time. What could be the reason for this, and what can I do to solve this issue?
-
@Shivam-Sehgal , are you able to ADB into VOXL2 and download the PX4 log from the flight?
Also, what SDK version were you using?
-
@Alex-Kushleyev , I am unable to ADB into VOXL2 today but I did download the flight controller log file after I was able to log in again that day from QGC.
https://review.px4.io/plot_app?log=81e3f3cc-1cf2-419a-8202-073a9dd46c3e link to flight review for the log file. I don't remember the sdk version.

@Alex-Kushleyev My Voxl SDK version is 1.1.2.

@Shivam-Sehgal , I have reviewed the log and unfortunately do not see any issues. The log terminates prematurely (before the crash), which may suggest that the PX4 process crashed (as opposed to a sensor issue or ESC issue, causing motor to stop, for example). But this is just a guess.
SDK 1.1.2 is quite old, we recommend using latest SDK if possible, since we always make improvements and fixes.
My recommendation is to get the vehicle back up and running and try to migrate to SDK 1.3.
-
@Alex-Kushleyev i can update the system but I am unable to connect to voxl 2. How can I update the system?
-
@Shivam-Sehgal , quick question.. So after the crash, were you able to connect to VOXL2 (how? ADB or wifi) to get the log from it? And now it no longer connects using ADB?
Here is unbricking procedure for VOX2 https://docs.modalai.com/voxl2-unbricking/, however that is typically done when a software update fails or the file system.
Can you please clarify whether you were able to use VOXL2 between the time after crash and now?
-
@Alex-Kushleyev Yes I was able to connect to drone both via wifi and adb that day, then next day I wasn't able to do so.
(Some Observation if it helps)
Also, I have 3 other starling drone in all of them there are four blue lights on the ESC that constantly flash.
In the one that does not connect there is no flashing. -
@Alex-Kushleyev should I follow the unbricking process?
-
@Shivam-Sehgal , Yes, you should try it, however i am not sure whether the recovery attempt will be successful. Typically unbricking is required when something goes wrong during SDK update or something like that, when the system is left in incomplete state. In your case, the drone was flying and stopped responding after a crash. The fact that it shut off during flight could mean there was a pre-existing issue (before the crash) which may be causing the board not to boot now. However, it is worth to try the unbricking and if does not work, please contact our RMA department, they will help you out.

@Alex-Kushleyev I did not unbrick it it had opened the voxl2 board and I was able to connect to it, then when I closed it it did not connect again.
What I found out is when the hires and tracking camera are connected to the board I am unable to connect to the drone. What could be the reason for this? -
@Shivam-Sehgal , most likely one of the camera flex cables is broken and it is shorting one of the power rails to ground, which prevents voxl2 from booting. I suggest trying to connect one camera at a time to narrow down the issue to a specific camera and then inspect the “bad” camera’s flex cable or extension flex cable.
-
@Alex-Kushleyev I connected both cameras to the other connector on which tof sensor was connected. I could connect to the board. Also the tof sensor worked on the other board.
But I could not connect to the tracking and hires camera, I could only connected to TOF sensor.
-
@Shivam-Sehgal I connected the cameras back in their basic configration that it is shipped with.
Then I ran voxl-camera-cameras and set it to 06 - D0005 Starling pmd-tof imx214 hires ov7251 tracking.

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