Questions about 64MP on 64bit bullseye system（Pi 4B）

Raspberry Pi Cameras

When I put this in the terminal:

libcamera-still -t 0 --viewfinder-width 2312 --viewfinder-height 1736

It says:

I can hear the sound of autofocus module but it doesn’t work.
Then I try:

libcamera-still --list-cameras

It says:

That’s right.
But then I input this:

vcgencmd get_camera

It says:

supported=1 detected=0, libcamera interfaces=1

I don’t know what happened and I use many ways from Internet to fix it but it seems useless.

I need information on the size of storage you have allocated to the gpu
cat /proc/meminfo

@Lumina

I don’t see a problem. Generally speaking, fd21 is a problem of gpu memory allocation, but it has already taken effect there. I now suspect it is the display problem.

You can try

libcamera-still -t 5000 -n -o test.jpg

It worked.
But no preview window.

@Lumina

This is to make sure the camera is normal, now it is certain that there is a problem with the display, are you using the display, or a remote connection

7

Remote connection（vnc）

8

@Lumina

i try on vnc ,and it’s work

There are two options:

  1. you display resoultions too high，try lowering the resolution
  2. try it on you raspberrypi,not vnc
9

I changed a display but this time it said:

failed to import fd 20
10

@Lumina

Strange. Can you try it on the raspberrypi ,not vnc?
