Multi-container setup unable to detect picamera

Product support
, , ,
1

Hi there, i’ve been trying to run a multi-container setup with picamera. However it seems that the container is unable to detect the camera even though i’ve set the HostOS config.txt

picamera container -
vcgencmd get_camera returns supported=0 detected=0
uname -a - Linux raspberrypi 5.10.83-v7 #1 SMP Tue Dec 7 13:42:57 UTC 2021 armv7l GNU/Linux

tried the following solutions:

  • sudo modprobe bcm2835-v4l2 inside the picamera container.
  • installed raspi-config turn on legacy camera. but it doesnt prompt reboot, with a manual reboot.

according to the documentation for the HostOS, the custom configuration settings.
BALENA_HOST_CONFIG_start_x = 1
BALENA_HOST_CONFIG_gpu_mem = 256
BALENA_HOST_CONFIG_fixup_file = fixup_x.dat
BALENA_HOST_CONFIG_start_file = start_x.elf

the docker-compose file for the multi-container setup

version: '2'
services:
  picamera:

    devices:

and the dockerfile to build the camera image.

i’ve also noticed that the builds do not include the binaries for /opt , not sure if that is intended for balenalib/raspberrypi3-debian builds. would be great if someone could clarify my doubts.

another question would be, should i be building my binaries on the HostOS layer instead of in the container layer? thinking that it’s meant to be shared in the future when i add more containers in.

Hi kayige

First I’d like to ask about which docs are you following? I’d like to confirm that you’re using an up to date source.

There’s a sample app at GitHub - balena-io-playground/libcamera-apps: Example repo to showcase Raspberry Pi's new libcamera stack on balenaOS that you can use to check that the camera can be detected. Could you try to run this and see if it works as expected?

You can also use this as a reference. For example, check libcamera-apps/balena.yml at master · balena-io-playground/libcamera-apps · GitHub you’ll see that there are specific fleet config vars defined.

If that one doesn’t work, there’s also another app at GitHub - balenalabs/balena-cam: Network Camera with Raspberry Pi and WebRTC. Tutorial:

And also could you share which OS version you’re running? And if none of the above works, the result of dmesg would be useful

Cheers
Ramiro

Hi ramiorgm

I took references from the following sources:
sample app: balena-cam/balena-cam at master · balenalabs/balena-cam · GitHub
docker-compose: docker-compose.yml fields - Balena Documentation
base images: Balena base images - Balena Documentation
configuration: Advanced boot settings - Balena Documentation

Currently i’m running HostOS on version 2.94.4

This is the current dmesg from the build im working on.

@kayige what example are you trying to run?

Could you please confirm the device you are using, the camera model plus the OS version? I will try to reproduce! Thanks!

9

i’m using a Raspberry pi 3 B+ Rev 1.0, Linux version 5.10.83-v7 (oe-user@oe-host) (arm-poky-linux-gnueabi-gcc (GCC) 11.2.0, GNU ld (GNU Binutils) 2.37.20210721)

Running HostOS Version: balenaOS 2.94.4

Hi @kayyige

The issue may be related to Pi3B+ running 64bit OS.

Can you go to the Device configuration tab on your device and tell me what the contents of Define DT overlays is? Or just share a screenshot of all the variables which are defined for the fleet or device

Thanks, Ramiro

Hi @ramirogm,

I’m currently running on Pi3B+ with HostOS thats 32bit though.
Here’s the device configuration and custom configuration screenshots.

so far i’ve managed to build the docker images on balenalib images.
balenalib/raspberrypi3-debian:stretch
but haven’t made any progress as to getting vcgencmd get_camera to detect the legacy camera on the container.

14

I cannot tell from your screenshot. Does

your dt-overlays contains vc4-fkms-v3d if so can you change it to vc4-kms-v3d (or add vc4-kms-v3d if there’s none).

16

yup it does have vc4-kms-v3d its set in my fleet configuration.

17

Not sure if this helps, tried a raspistill -v -o out.png

checked the HostOS container config.txt to confirm i have the vc4-kms-v3d

@aethernet @ramirogm after a week of testing it seems that the balena images are missing the dt-blob.bin inside the /boot directory on the HostOS.

Copying that into the HostOS resolves vcgencmd get_camera, its now able to detect the pi camera inside the camera container.
However I’m left with figuring out the mmal issue where the camera component could not be created.

19

Hi @kayige

Glad to hear that you’re making progress. One comment, the actual boot files are at /mnt/boot. Here’s a reference about that BalenaOS Masterclass - Balena Documentation

In that folder, you may have a dt-blob.bin file ( depending on the device ) along with others. For example cat /mnt/boot/config.txt which I think is the one you posted above.

About the mmal error, was any other container running at the same time that could have grabbed the camera?

Ramiro

20

@ramirogm i do have a log container running together with the camera one. tried to deploy with just the log container to see if there’s conflicts but still have the same set of mmal errors.

mmal_vc_shm_init: could not initialize vc shared memory service mmal: mmal_vc_component_create: failed to initialise shm for 'vc.camera_info' (7:EIO) mmal: mmal_component_create_core: could not create component 'vc.camera_info' (7) mmal: Failed to create camera_info component

22

Hi @kayige

It looks like the error is different now, it’s 7:EIO instead of 1:ENOMEM, so I’d like to understand what changed.

Could you share your docker-compose file? It would help us to understand the whole setup you have and try to find the issue. It would be useful also to have the last dmesg output when you get that error.

Thanks
Ramiro

@ramirogm i’ve managed to resolve the issue and got the legacy camera to work.

the 2 key points were,

  1. HostOS requires the dt-blob.bin in /mnt/boot for camera detection.
  2. Docker build requires a copy of the original /opt/vc during the build process. This is because libmmal requires the header files and the lib files to work properly.

@kayige Thanks for letting us know how you resolved the issue and got the legacy camera to work. We’ll look at this in more detail and see if we can add this to one of our examples in case others are looking for the same.
