No RPi Camera v2.1 detected on Nerves Livebook running on RPi Zero 2 W

Hi all,

I’m just getting started with Nerves (and really Elixir for that matter). I’m trying to interface with a Raspberry Pi Camera Module V2.1 from a Raspberry Pi Zero 2 W. I tried just grabbing the Nerves Livebook (0.18.0) from the Nerves Burner tool and running the following command in IEx after SSHing in:

iex(livebook@nerves-1a51.local)1> cmd("libcamera-jpeg --list-cameras")
No cameras available!
0

I did a bit of snooping around this forum and other places and saw that people have had some issues like this, even with the same IMX219 sensor that I’m using (like here). Basically just wondering if I’m doing something obviously wrong here, if there’s a more streamlined fix than what’s outlined in the linked post, or if the solution provided in the post is the best way to enable support for this particular camera module.

Also just to quickly add: I did test grabbing images from the camera from a stock Raspberry Pi OS image, which worked fine, so I presume this is not a hardware issue.

Thanks all for your help.

Hmm.. let’s see. I don’t know top of mind how to check which exact system you are on from what Nerves Burner gives you. If it spits out that info, please share it :slight_smile:

To check if the overlay exists:

ls "/boot/overlays

To check if it has loaded:

lsmod

If not in that list there should be something in the boot log:

dmesg

If you share those it light give a clue :slight_smile:

Hi lawik, thanks so much for the response. Here’s some more info about my system:

Overlays (by no means an expert, but it seems like seeing imx219.dtbo is a good thing here?):

Thanks again for your help :slight_smile:

Ugh. It looks like the imx219 driver isn’t loading based on your lsmod. I don’t know how this could be the case, but the usual suspect is that some dependent kernel driver isn’t available in the image. If it’s easy to run Raspberry Pi OS and run dmesg and lsmod, I think that I can infer what’s missing. The other option is to wait until next week when I make a pass on Nerves systems. I’ll look through the cameras I have and see if I can replicate.

Second thing to try if the imx219 driver loads, but you still don’t see a camera is to run libcamera with logging turned on:

cmd("LIBCAMERA_LOG_LEVELS=*:DEBUG libcamera-jpeg –list-cameras")

Hi @fhunleth, thanks for the reply! Here’s the output of dmesg and lsmod from Raspberry Pi OS:

(Going to post dmesg in a follow up post since I’ve exceeded the character count.)

Weirdly, I did not get any extra info with the more verbose logging:

iex(1)> cmd("modprobe imx219")
0
iex(2)> cmd("LIBCAMERA_LOG_LEVELS=*:DEBUG libcamera-jpeg --list-cameras")
No cameras available!
0

Also, I was able to “fix” this issue (I don’t know if this fix is the right way to do it, but I figured I would include the details here in case it proves to be helpful). I cloned the nerves_system_rpi0_2 repo and made the following change to linux-6.12.defconfig.

-CONFIG_VIDEO_BCM2835_UNICAM=m
+CONFIG_VIDEO_BCM2835_UNICAM_LEGACY=m

I made a new nerves app just with mix nerves.new hello_nerves, and then I pointed to my local copy of nerves_system_rpi0_2 and compiled the firmware from there.
After this I still had to load the unicam driver manually (cmd("modprobe bcm2835_unicam"), but after that I was able to see the camera show up and take pictures. Again, totally unsure of how helpful this is, just thought I’d mention it in case it is useful.

This is super helpful! This has happened a couple times where a Linux kernel has diverged from userland for Raspberry Pi camera support. There are updates to the libcamera library and libcamera-jpegthat we don’t have in Nerves. I can’t tell from the commit messages that it will allow us to not need the legacy driver, but we can try. Hopefully it will make things “just work” since it’s not ideal to have to run modprobe manually.

I’ll post PR links when I have them. Thanks for finding this. Hopefully this is the only issue!
