Voxl2 crashed
-
Hi ModalAI team,
I'm having a voxl2 crash, I don't know why. I tried to connect voxl 2 using adb and ssh but no response.
Is there a way to see the system log or other way to find the problem?
And I find DBG_UART12 at J3 PIN-OUT of voxl2. Can I use it to check if voxl2 is completely crashed or just adb and ssh not working?
If possible, what is the DBG_UART12's reference voltage and baudrate.thanks,
Simon@SimonLi can you please follow the steps here? https://docs.modalai.com/voxl2-unbricking/

The problem I encountered was that ADB and SSH did not respond after booting VOXL2 for a while, but it worked after rebooting.Not ADB is unable to detect VOXL2.
So I want to see the system log or other way to find the problem.
Thanks,

Although ADB and SSH are unresponsive, I can see the device in Windows 11's Device Manager.Simon

@SimonLi It'll be easier to help with debugging if you're using a linux machine, preferably with Ubuntu 18 or newer.
What is the device enumerating as? Does it give a specific name / device type? We've seen weirdness with ADB + WSL in the past
@tom
When ADB and SSH are unresponsive and I also repluged the USB, it also showed the same name.
The device name is "KONA-QRD_SN:886DD761" in Windows 11's Device Manager.The situation doesn't always happen when VOXL2 booted.
And it happens approximately a few minutes after VOXL2 boots, not immediately after booting.Simon

@SimonLi could there be software running that it is causing it to overheat? Maybe put a fan over it so you can get it booted and debug what is going on?
@Moderator
I also suspected whether it was due to overheating, so I used voxl-inspect-cpu to check the CPU status.When ADB and SSH were unresponsive, the temperature was about 50°C~55°C, and voxl-inspect-cpu also didn't respond.
But if VOXL2 operated normally, there was no problem if the temperature had reached about 80°C.

@SimonLi Once it hits 90° C it will shut down. So, if you were running at 80° C for an extended period of time, it likely shut down.
You should put a fan on it and see if you can get it to boot, then disable all of the software, upgrade to the latest SDK, and see if you can bring things back up

Thanks, I will try it.Although the temperature will reach 80°C, there has been no shutdown at this temperature.
The temperature wasn't high when the problem occurred.So if the problem occurs and I want to view the system logs or use DBG_UART12 at J3 PIN-OUT of voxl2 to check.
What can I do?Simon
