CamHAL[ERR] Failed to find DevName for cameraId: 0, get video node: ov13b10 , devname: /dev/v4l-subdev1 #37

Can you provide a config file for your camera sensor (based on one of the existing files)?

I don't know where the file |
|
This is what you could provide - this is what the error log messages say, that "there is no aiqb file:ov13b10". There are several config files provided, which could be used as a template - and adapted to your specific sensor I think:
You might want to have a deeper look into the CameraHAL repo. |

Do you see some of the example pipelines under "https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api#pipeline-examples" working? |

I tried all of the example pipelines and all of them result in an error. I don't know how to set the |

Under "https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api#pipeline-examples" you can see example pipelines, where you can specify the device-name (in case the camera/sensor is not detected properly or is too exotic), e.g.:
Depending on the config files (you might want to look into the sample XML-config files for settings, parameters, naming, etc.), e.g.: https://github.com/intel/ipu6-camera-hal/blob/iotg_ipu6/config/linux/ipu6ep/sensors/ov13b10-wf.xml But there could easily HW-specifics depending on your camera, sensor, how it is connected (USB? Mipi-CSI?), virtual-ports being used, firmware flashed, etc. |

The camera is a built-in webcam for Google Chromebook Redrix. It is connected with i2c I think because it is |

also is this the right GitHub repo to create an issue? |

I've run into this issue - but only after upgrading to kernel 6.5, in 6.4 it was working fine. |
|
Do you use an USB based camera? Are certain kernel options (like CONFIG_MEDIA_USB_SUPPORT=y, CONFIG_USB_VIDEO_CLASS=y, CONFIG_USB_G_WEBCAM=y and CONFIG_MEDIA_CAMERA_SUPPORT=y) still enabled? Do you use an IPU based camera? How have you installed the IPU drivers (e.g. IPU6)? Also e.g. |
|
I use a Dell XPS 9320 and the fedora rpmfusion testing packages. I have all these packages installed, and akmod should be recompiling the ipu6 driver when needed. I haven't rebuilt the rpm's for hal/bin/icamerasrc again though after kernel change, not sure how that'd be feasible to do with rpm's either? For that I guess we'd need to convert those to akmod or something like it aswell. I do have the kernel module loaded: |
|
Do you have documented how you got it working with the previous kernel, do you have records about which versions of IPU-module, IPU bin and hal and icamerasrc you had installed? Was it just working, or did you create and add a camera-sensor specific config file (like this issue is about)? Would it be possible to downgrade the kernel again? The dev-team would anyway need logs to analyze further to see if upgrading the kernel did update dependencies as well which introduced changes looking like a regression? |

Just got a fix for this in another issue I'm also watching. After applying this intel/ipu6-drivers#22 (comment) fix manually everything works again! |

I still have the same error after applying the fix |

This also started happening to me, not entirely sure why, I have |
I have an IPU6 camera and I installed drivers for it with these commands:
On firefox, the camera is just a black rectangle. When running
sudo -E gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesink, I get this error:Full output:
Am I missing something? What should I do to get the camera to work? Is there something Intel needs to fix for it to work?
