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

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

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:

I can see on this video that it should work.
This is frustrating. No idea what I am doing wrong.
@jonasrejman @LoKau @jhud @spm
okay.
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
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:

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 … 
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.
I also emailed you about an remote assistance request.
Thank you!
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!
Thanks @Edward & team for getting libcamera-still --list-cameras working for me remotely. Unfortunately, it isn’t over yet.

UPDATE: Well, I guess it’s just the low memory on RPI Zero. Running libcamera-still -t 1 -o test.jpg --width 1920 WORKS!
It dawned on me that 16mp resolution is too large for pizero.
You can do something try:
sudo vi /boot/config.txt
add find line "dtoverlay=vc4-kms-v3d"then add “,cma-128”
like “dtoverlay=vc4-kms-v3d,cma-128”
Yep, that I have already in. In fact, this is what I have:
dtoverlay=vc4-kms-v3d,cma-128
max_framebuffers=2
gpu_mem=128
That doesn’t work for the full resolution. I actually don’t need the full resolution, lower is good enough I just want to keep the same field of view - i.e. don’t crop but resize.
You cant access this.
16mp is 4:3 ,1080p is 16:9.
if you want to use it in full resolution(include the full field of view),you can try pizero2w. They are also small and convenient.
Hello, I was wondering if you could explain how you were able to get the camera to work. I haven’t been able to try anything Edward suggested yet since I’m only in the lab at the end of the week. If you could give a step by step guide that would be greatly appreciated. Thank you!
Any tips or steps to get past the “Illegal instruction” error above yet?
@jhud : what did @Edward and team do to get libcamera working?
@spm @corkyskier - Arducam will fix their installation script, as the issue is there, hopefully soon so it’ll just start to work after you reinstall. We should hear about it here, in this thread.
The issue is in imx519.json tuning file which lives somewhere in /usr/lib/… (I’m out of reach of my RPI now so this is from the top of my head). That file needs to be replaced by a different version. I’m now not sure where they got the right version from - probably from one of their custom libcamera packages that we install as per their standard installation instruction. They haven’t downloaded anything different to my RPI.
Got it, I really appreciate it. Is there anything that can be done in the meantime or do we have to wait for them to fix their script?
