We need some more detailed information,
camera-bug-report -t 5 -o bug.txt -c "libcamera-still -t 1000 -o test.jpg"
it will generate a bug.txt file, please put the information in the code block reply, otherwise there will be unnecessary problems with the display.
The bug.txt file is too large to put into the body of this email. Here is the stdout output

I found that the camera will work with a GPU ram allocation of 40 Mb, but not with less than that, or with 76Mb.
@lefsky
You can try to modify your config.txt
sudo vi /boot/config.txt
dtoverlay=vc4-kms-v3d,cma-256 become dtoverlay=vc4-kms-v3d,cma-512
Restart after changing and try again
I was using cma-512 already. And it was the GPU memory change that did it for me.
I’m running into same issue with “Failed to allocate buffers” what exact change did solve your issue? Is it setting GPU allocation through raspi-config?
Same issue, any solution? I also updated cmdline.txt with cma=400, tried to assign 128 to GPU, same error.

Okey,I see nothing wrong with your configuration information.
We can’t reproduce your problem, everything seems to be fine with us. I have some suggestions here:
cat /proc/meminfo CmaTotal and CmaFree should be around 500000kBIf you still have problems, send me the following information
dmesg
CmaTotal: 524288 kB
CmaFree: 351144 kB
Reduce screen resolution to 600x800, now it works.
CmaTotal: 524288 kB
CmaFree: 484732 kB
@nack
ok, did you lower the resolution of the monitor?
Someone has also reduced the resolution of the screen before, I think this is a solution that can temporarily solve this problem
Yes, reduced screen resolution to 800x600, just tested all 4 camera’s, all work! Thank’s a lot.
hey, i was working with two 16MP cameras in a raspberry pi cm4 with 4GB RAM.
I am trying to capture the images simultaneously for stereo setup, i can capture my first set of images but when i try to capture second set i get this failed to allocate memory issue
I am using below libcamera drivers:
ii libcamera-apps 0.0.10 arm64 libcamera-apps
ii libcamera-dev 0.0.10 arm64 libcamera
ans i am using picamera2 version 0.3.6
@Edward please help us to solve this problem
