How to debug camera crash?

ChristianN

Our Oak 1, running on a raspberry pi, periodically dies. I believe this might be a power issue, but we have it on an externally powered USB hub so that also feels unlikely. Here are some logs

The actual camera script crashes with this, which by itself doesn't tell us much

RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'h265' (X_LINK_ERROR)'

I know the camera is dying from a usb connection issue because we see this in the sys logs

usb 1-1: USB disconnect, device number 30

What I'd like to know is if there is any way of getting a crash report from the Oak itself? Is there a way to determine if it's a power issue, and if so, what limitations are being hit by the camera?

Thanks so much!

Hi @ChristianN ,
it's either power or comms issue (docs here, see connection drop debugging).
Getting crash log:
https://docs.luxonis.com/software/depthai/examples/crash_report/
But likely it will say no crash log found, as there wasn't a FW crash, but rather power/comms issue. To determine power issue best would be to scope it (if you have that equipment), or rather use Y-adapter or different powered USB hub.
