"ERROR: the system appears to be configured for the legacy camera stack"

[christianbaun]

Hello,

I wonder why tools like libcamera-hello do not work with the RPi-image. The libcamera-tools missing first, but I installed them with:

$ sudo apt install libcamera-apps

$ libcamera-hello 
ERROR: the system appears to be configured for the legacy camera stack

In raspi-config, the camera is enabled. I also gave the GPU 256 MB memory in raspi-config.

$ v4l2-ctl --list-devices
bcm2835-codec-decode (platform:bcm2835-codec):
	/dev/video10
	/dev/video11
	/dev/video12
	/dev/video18

bcm2835-isp (platform:bcm2835-isp):
	/dev/video13
	/dev/video14
	/dev/video15
	/dev/video16

mmal service 16.1 (platform:bcm2835-v4l2-0):
	/dev/video0

It tried using the RasPi Camera module v2 and the RasPi HQ Camera module. But this does not change anything.

Has anyone here observed the same issue and/or an idea how to solve it?

The libcamera-hello and other libcamera tools are all working under the new Debian 11 operating system Bullseye.
This RPi-image is the 'old' Debian 10 Buster. We are planning to release a new RPi-image with Bullseye soon.

Thank you for the quick response. I did not check this before:

$ cat /etc/debian_version 
10.11

As you mentioned here, no 64-bit versions of the tools raspistill, raspivid, ... for the legacy camera software stack exist, but I was able to get the libcamera stack tools running in your RPi-image with Buster.

The error message of libcamera-hello helped me to find a solution here.

$ libcamera-hello --verbose

After I did a rpi-update:

$ sudo rpi-update

The libcamera-tools work well. e.g.

$ libcamera-still -t 0

sudo rpi-update really works.
