Arducam 64mp random *** failed to allocate capture buffers *** with added cma-512

Hi!

Pi 4 with 2G here.

I’m getting random errors with memory allocation. Sometimes command needs to be executed several times to capture an image.

dtoverlay=vc4-kms-v3d,cma-512 was added.

CmaTotal: 524288 kB
CmaFree: 426756 kB

Shooting in JPG usually works fine. Adding -r for Raw output crashes randomly. Will post logs in next post

  • repeating command after it fails without changing anything eventually works. I guess this is software problem. Lets fix it.

Hi, @itsskin

You need to set timeout in the command.

libcamera-still -t 10000 -r --nopreview --timestamp --denoise cdn_off --gain 0 --shutter 2000000

thank you! will give it a try. what is the reason for this?

This may be a bug, we need to check it.

-t 10000 and -t 15000 do not solve the problem. Still getting random crashes

I am also seeing random failures to capture jpegs - with the failure to allocate a buffer. I’m on a 8GB Raspberry Pi 4 so there should be plenty of memory. I haven’t kept statistics, but it seems the frequency of random failures for jpegs depends on the display connected - a larger display 1920x1200 produces more failures than 1920x1080. The frequency seems to drop when the GPU memory is lowered to 40. That may be a coincidence – not tried anything systematic, but it just seems that there is something like a bug preventing the memory from being allocated. It may take 5 times of repeatedly trying to capture before it finally works, and at other times it works perfectly over and over.

Exactly same here. It’s statistics :slight_smile:

Hi, @itsskin

You could try testing just saving the image without setting the controls. Is it possible to save the image multiple times.

Same here. Seems only libcamera-jpeg is somewhat stable. Any use of libcamera-still with keypress and other options throws random errors.

I’m experiencing the same issue. Did this ever get solved?

Hi, @AnotherDredd

Sorry to reply you so late.

After allocating 512M memory, the buffer allocation error still occurs when saving the maximum resolution image. We are consulting the Raspberry Pi official, once there is a new solution, we will notify you in time.

What’s the ETA?

Camera is unstable and unusable in this state.

Not what you want to hear but you can lower the resolution.
libcamera-still -t 5000 -n --width 600 --height 400 -o image.jpg

I bought this camera for 64MP dng output. Lovering is not an option.

SupportTeam, any news?
