Pi Camera not detected with IVPort Dual V2

[paol-gornek]

I currently have an ivport v2 dual module connected to my rapsberry pi 3 model B v1.2, to which I connect a single camera (pi camera rev 1.3, ov5647 sensor) for testing. I followed the commands listed in this git: https://github.com/ivmech/ivport-v2, but when you get to the command: vcgencmd get_camera, everything is 0.

I've done a lot of research to understand the problem and fix it. I've added the following lines to the /boot/config.txt file :

lines added : dtoverlay=ov5647 start_x=1 gpu_mem=128

I have updated the firmware : sudo rpi-update.

but still the same problem :

(to be sure the cameras work correctly without the module with libcamera i've already tried it)

Here are the traces of the i2cdetect -y 1 command with a camera connected :
