pi camera module v2 not detected

Hello,

I followed the troubelshooting, but nothing sorts this out:

Camera connected to the camera port

$ grep gpu /boot/firmware/config.txt

The module is a genuine one.
rpicam-still -o cam.jpg worked like others rpicam utilities.

I tried MotionEyeOS, but it always fail with start4.elf is not compatible, either with the writeimage.sh script or with the RPI image writing software.

Any clue?
