[BUG] Camera Module 3 not detected on RPi4b 4G Ubuntu 22.04

Describe the bug Camera module 3 on RPi 4b 4GB Ubuntu 22.04. (Ubuntu 22.04.3 LTS (GNU/Linux 5.15.0-1034-raspi aarch64)) Compiled libcamera and libcamera-apps but get the message "no cameras available". I have confirmed that this exact hardware functions when using Raspbian, where I can run libcamera.

Bug report report0.txt

I ran the bug report utility again as root to get dmesg info: report1.txt

I have a hat connected to gpio with a fan and an OLED display that communicates over I2c (may be relevant). https://github.com/geeekpi/RPiFEBP https://www.amazon.com/GeeekPi-Raspberr ... B09MVL8BWQ

Note

by adding the line start_x=1 to /boot/firmware/config.txt i can get the camera to be detected by v4l and to show up as /dev/video0, but not to work with libcamera:

Adding start_x=1 is a dead end as Camera Module 3 is not supported by the legacy stack. It'll identify, but will never work.

Raspberry Pi don't control the Ubuntu kernel builds. Are the relevant modules built? modinfo imx708 and modinfo dw9807-vcm. Does imx708.dtbo exist in /boot/overlays (or whatever the Ubuntu equivalent is)?

sudo vclog -m from https://github.com/raspberrypi/utils/tree/master/vclog can read the firmware logs on systems which don't have vcdbg. That should tell you if the firmware has failed to apply the overlay for whatever reason.

First, thank you @6by9 for your help. TLDR it appears I'm missing those modules. Not sure if I'd have to build a new kernel or something.

Following are the results of those commands:

atticus@rospi:~  
$ modinfo imx708
modinfo: ERROR: Module imx708 not found.

atticus@rospi:~

/boot/firmware/overlays/imx296.dtbo      /boot/firmware/overlays/imx519.dtbo.bak

I was only able to get "bus error" from vclog, but I have included my install process in hopes there is some error I made.

however I forgot to make sure dw9807-vcm was enabled

atticus@rospi:~  
$ modinfo dw9807-vcm
modinfo: ERROR: Module dw9807-vcm not found.

and imx708.dtbo still doesn't exist as an overlay, so I'm gonna need to work on that (can likely also copy from an rpi repo).

@6by9 I recompiled the kernel again and this time added the imx708 dtbo and the dw9807-vcm, but am running into the same issue. any ideas?

not sure if maybe something is still lacking in the kernel or if it might be a simpler config error here.

camera_auto_detect should be set to 1 to enable libcamera support (I believe).

@SachetK my previous post was unclear, I have now edited it to indicate that I initially tried with camera_auto_detect=1 and then when that resulted in no cameras available I changed it to manually specifying the camera

That suggests the sensor probed correctly, but the device driver could not be opened for some reason.

@atticusrussell do you see any error messages in dmesg after boot related to the imx708? Also does the following command successfully give an output:

v4l2-ctl -d /dev/v4l-subdev0 --list-subdev-mbus-codes

Also, could you run camera-bug-report and attach the output again after your changes to get probe working?

Another thing to try is to see if another camera works in your environment. Do you have another Raspberry Pi camera that you could use?

I'd guess that the media controller node has been created, but due to some dependent device not having probed the /dev/videoN node hasn't been registered. I can recreate that by blacklisting dw9807_vcm (I happen to be on a 6.5 kernel here, but that shouldn't matter):

pi@raspberrypi:~ $ media-ctl -p -d 4

imx708:
 [fwnode] dev=10-000c, node=/soc/i2c0mux/i2c@1/dw9817@c
unicam fe801000.csi:

ie the imx708 node is waiting for dw9817 to enumerate. /dev/video0 doesn't exist until all dependencies are met, which calls unicam_async_complete and that registers the /dev/videoN nodes.

@naushir the following is the output of bug-report (with the later mentioned USB HD web camera disconnected for simplicity): bugreport3.txt

atticus@rospi:~  
$ v4l2-ctl -d /dev/v4l-subdev0 --list-subdev-mbus-codes
Cannot open device /dev/v4l-subdev0, exiting.

The output of searching dmesg for the sensor only results in the name of the kernel that I modified (not predicting that it would show up as a false positive in dmesg when picking the name)

I found a generic USB "HD Webcam" without branding on it that works on my pi with libcamera. Here is the output of dmesg (nothing grepped) with it connected, as well as the non-working RPi Camera Module 3 connected

As @6by9 mentioned, this looks like the sensor probe has not fully completed (likely due waiting for dw9817 to enumerate), and the media device is not fully registered.

5.15 is pretty old in our book. https://github.com/torvalds/linux/commit/517fd2b6a058bc4f23735ab9a9e6b0d5c56876d1 to add v4l2-async/pending_async_subdevices was added in 5.12, so that implies that nothing is registering for v4l2-async.

lsmod should include at least imx708, bcm2835_unicam, videobuf2_dma_contig, videobuf2_memops, videobuf2_v4l2, videodev, videobuf2_common, v4l2_async, dw9807_vcm. Not having a unicam Media Controller node registered implies that bcm2835_unicam isn't loading, let alone the rest.

Sorry, but this is getting to the stage of being Ubuntu specific and therefore probably better to be asking Canonical about. Or switch to the rpi-6.1.y kernel and our standard defconfig to ensure you've built everything necessary.

Thanks for all the help. I'm pretty new to messing with the kernel, so have a few questions about how to proceed with updating to a newer kernel.

I'm intentionally on Ubuntu 22.04 LTS for compatibility with ROS Humble.

AFAIK the kernel goes under any distro-specific customization, so in theory could I simply compile 6.1y from raspberrypi/linux and apply the .deb patches to Ubuntu?

Thus far I have been copying changes from raspberrypi/linux over to the Ubuntu provided linux-raspi kernel on the branch applied/ubuntu/jammy-updates 5.15.0-1035.38 (patches applied).

Can I run a kernel newer than 5.15 with ubuntu 22.04 (jammy)? I notice that there's a 6.2.X kernel in the ubuntu rpi-kernel repo tagged with mantic (23.10) and lunar (23.04). If so, does it matter whether I get the newer kernel from raspberrypi/linux or rpi-kernel, and would either choice be better?

Thanks again for all your help.

Potentially you can take the kernel package from the later Ubuntu release, but I'm not involved in packaging to give details.

Largely the kernel version is independent of almost all userspace stuff as the kernel should offer a stable userspace ABI, but there are sometimes glitches in that.

@6by9 I managed to update my kernel to 6.2.0-1004-raspi using a package from Ubuntu Lunar, as detailed in this askubuntu post I made, however my issues with libcamera and the Raspberry Pi Camera Module 3 persist.

I think I have the correct drivers now. I have now reproduced the issue you predicted with imx708 as a pending_async_subdevice.

Not sure what my next step should be. How do I get dw9817 to enumerate, like you mentioned.

Also I have manually specified the sensor:

@atticusrussell any particular reason you are using Ubuntu and not a Raspberry Pi OS image? In the latter, Camera v3 will "just work" as intended.

The VCM driver is dw9807_vcm. It supports multiple compatible strings to differentiate between dw9807 and dw9817

If your question is about why as an OS, I am using Ubuntu in order to have compatibility with ROS as this computer is for my robot.

If you're asking about why I'm not trying to use a Raspberry pi kernel like from the raspberrypi/linux repo, I am still open to trying that. The reason I have not yet is that I was able to install the ubuntu 6.2.X kernel without compiling it myself (which is slightly tedious), and that I was slightly apprehensive to mix kernels and userspaces (although the kernel intended for raspian should be fine to run Ubuntu I think).

Ah as I was suspecting. Thanks for confirming! I'll first try enabling it in menuconfig when recompiling the Ubuntu kernel 6.2.x, and if that fails I'll look for any recompiled raspberrypi/linux 6.1y .deb files, and failing that I'll try to compile raspberrypi/linux and install that kernel.

That order of operations seem sane?

Any further updates on this issue? If not, I'll close this shortly.

I took a bit of a break from trying to solve this issue and focused on just using a USB webcam I have. I still intend to try with a different kernel version, but I might not get around to it for a week or so. If there is a more relevant place for me to file an issue I would say go ahead and close the issue after I re-file it, but otherwise might be good to leave open in case others come across this issue.

I'll close this one now. Please do create another issue if you still run into problems when you revisit this.
