RPI Zero 1.3 + 16mpx IMX519 -> illegal operation

Raspberry Pi Cameras
39

@Edward, same question for my 1B+ model.
I agree that it is quite old but I don’t think I’m the only one using this device.

40

@jhud @LoKau

First of all I would like to express my apologies.

This is indeed a known issue and we have addressed similar issues before. We thought that the official solved this problem permanently, so we didn’t treat these devices specially. Now it seems that the problem has appeared again, so I need to solve it again, and release a special version.

Now I’ve purchased the hardware, but it hasn’t arrived yet.

If you are willing to give me some patience, I will also be responsible to the end.

41

@Edward

Thank you for the update. I’ll wait more and will ask the seller if they’re ok me possibly returning the camera later. But hoping you’ll make it to work.

Re the problem. I have no technical insight into it but as a different camera works fine, this must be specific somehow to your cam, correct?

42

Hi @Edward, just touching base if there is any development with our issue. Thanks

43

@jhud

It is still in the logistics stage, and I will confirm with the purchasing department again.

Same issue and errors here on my Pi zero W: fresh install with new hardware/software as of today.

6.1.21+

$ libcamera-hello

@jhud @LoKau @spm

I just got the hardware and am expected to fix him in these two days.

@jhud @spm @LoKau

I have fixed the problem, please reinstall our libcamera.

wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh
chmod +x ./install_pivariety_pkgs.sh
./install_pivariety_pkgs.sh -p libcamera
./install_pivariety_pkgs.sh -p libcamera_apps

then try again

47

@Edward

Unless I’ve done something wrong running the instructions (done twice, second time with sudo), no change for me ;(

$ libcamera-hello

[0:00:54.936916000] [503]  INFO Camera camera_manager.cpp:299 libcamera v0.0.0+4225-74d023d8

Not sure if the bellow warning was there before and has any impact:

Same error after reinstalling libcamera as instructed:

$ libcamera-hello --list-cameras

Also had the Repository is broken warning on install.

Hello.

I just got the 16MP camera with adapter cable and pi zero W.
This is the cable - I also think its correctly connected - all pins always show towards the board.

I do not know exactly which version of the pi zero, but I am experiencing similar problems:

[0:45:05.988382216] [10512] INFO Camera camera_manager.cpp:299 libcamera v0.0.0+4225-74d023d8
Illegal instruction

I tried the installation instructions:
https://docs.arducam.com/Raspberry-Pi-Camera/Native-camera/Quick-Start-Guide/#software-guide_1

These are my config.txt settings:

dtparam=audio=on
camera_auto_detect=1
display_auto_detect=1
dtoverlay=vc4-kms-v3d,cma-128
max_framebuffers=2
disable_overscan=1
[cm4]
otg_mode=1
[all]
[pi4]
arm_boost=1
[all]
dtoverlay=imx519

On headless, with GUI, with the original 5.xxxx version of the os and also with full updated 6.1.21 and later.

I have this error, but somewhere else it is said that this is not a problem:
W: Repository is broken: libcamera-apps:armhf (= 0~git20230309+4def288-1) has no Size information

Is there a comprehensive guide how to solve this on the pi zeros W ?
Does the camera has some sort of small light to confirm that it is correctly connected?

I did one more attempt, with info from this forum:

  1. Download image from:
    https://downloads.raspberrypi.org/raspios_lite_armhf/images/raspios_lite_armhf-2023-02-22/2023-02-21-raspios-bullseye-armhf-lite.img.xz

  2. Installed Arducam software:

wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh
chmod +x install_pivariety_pkgs.sh
./install_pivariety_pkgs.sh -p libcamera_dev
./install_pivariety_pkgs.sh -p libcamera_apps
./install_pivariety_pkgs.sh -p imx519_kernel_driver_low_speed

  1. Modified config.txt:
    dtparam=audio=on
    camera_auto_detect=1
    display_auto_detect=1
    dtoverlay=vc4-kms-v3d,cma-96
    max_framebuffers=2
    disable_overscan=1
    [cm4]
    otg_mode=1
    [all]
    [pi4]
    arm_boost=1
    [all]
    dtoverlay=imx519

  2. activated Glamor graphic acceleration via rspi-config

NO rpi-update
uname -a shows: Linux camera 5.15.84+
reboot

=> illegal operation

I can see on this video that it should work.

This is frustrating. No idea what I am doing wrong.

52

@jonasrejman @LoKau @jhud @spm

okay.

I tested again and nothing seems to be wrong I can support you guys remotely.

kernel must higher than 5.15.84(include 5.15.84) and Bullseye
I want to update the description, and the best way to reinstall is to first remove the libcamera

sudo apt remove libcamera0
./install_pivariety_pkgs.sh -l
./install_pivariety_pkgs.sh -p libcamera
./install_pivariety_pkgs.sh -p libcamera_apps

@Edward

I ran your commands above again, still the same problem.

I’ve noticed from your screenshot you have libcamera v0.0.0...3d8-dirty while I have:

@jhud

okay.

I can arrange for you remotely.

pls contact me ([email protected])

55

Thanks for the response. I did the above commands - still getting illegal operation.
It seems I have the 1.1 revision. I wrote you an email regarding remote support. I appreciate it very much.

→ it seems that the lib camera version you are using is the “dirty one” 3d8-dirty wheres we are getting the clean one. So we need to get dirty … :laughing:

56

@jonasrejman

I’ve set up remove access for 7:00 UTC time tomorrow (18/4). If you have an earlier one, pls let me know so we don’t waste too much time.

57

I also emailed you about an remote assistance request.
Thank you!

58

Thanks for the reply Edward!

It might be good if you provide a step-by-step guide how you arrived at this state,
starting with which os image you downloaded. This way we can follow your progress and hopefully get it to work. If you can get it to work from scratch - so should we.

Thanks!

59

Thanks @Edward & team for getting libcamera-still --list-cameras working for me remotely. Unfortunately, it isn’t over yet.
