Cameras supported=0 detected=0

[atrunyan]

I am getting supported=0 detected=0 when running vcgencmd get_camera even though I put the dt-blob.bin file into my boot folder during initial configuration and enabled cameras through raspi-config. What other steps could I take to fix this issue?

Hi atrunyan,
" supported=0" means the system was not able to find the dt-blob.bin file
Could you please check that:
1. You got the latest dt-blob bin file
2. You unzipped the file before putting it to the /boot partition

upd> Which StereoPi version and RaspiOS are you using?

Hi Realizator,

I have the same issue. I have downloaded dt-blob zip file from the url that you provided and unzipped it. I am using bookworm on Stereopi (CM3+), so I have tried putting dt-blob.bin file both in /boot and /boot/firmware but with no luck.

uname -a: 6.6.31+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux

Can you help me please?

Hello Ismud,

Bookworm has a new video subsystem (libcamera) without stereoscopic support. We'll try to use libcamera, but it's challenging.

You can use Buster, which has MMAL/raspivid/raspistill video stack. You can also download the ready-to-use Buster with the latest kernel and OpenCV installed: https://app.mediafire.com/nzr90vj8wp1l3
