Segmentation fault, Arducam 16MP IMX519

Raspberry Pi Cameras libcamera

Hi, I recently received a 16MP autofocus ArduCam and followed the steps from the start guide:

I am currently using a fresh install of the RaspberryPi OS Bullseye on a Rpi4.

After installing the necessary software, I run the command:

libcamera-still -t 5000 -o test.jpg

A segmentation fault occurs after the command:

$ libcamera-still -t 5000 -o test.jpg
Made X/EGL preview window

Segmentation fault

Does anybody know how to solve this error?

If live preview command is used, it does not cause error:

libcamera-still -t 0
2

Can you provide this information?

3

Also you can try to turn off the preview:
libcamera-still -t 5000 -o test.jpg -n
Most likely it’s a preview issue.

4

Turning off the preview allowed the image to be saved and no segmentation fault was shown. Thanks!

5

A customer said before that Glamor graphic acceleration doesn’t work on Pi4, maybe you can try turning it off.

I have the same problem where ‘libcamera-hello --list-cameras’ returns a list of cameras and then ‘segmentation fault’.
But I also have my own libcamera-app, so I can run it in a debugger. And there I found that my app can’t read the image-buffer returned by mmap. “error: Cannot access memory at address …”
But, if I run ‘sudo libcamera-hello --list-cameras’ then no segmentation fault occur.
So there seems to be some access-right problem assosiated with sharing memory
