I have a Raspberry pi 4 with a clean install of Buster.
I followed the pdf for the camera and did the following
information
I opened /boot/config.txt:
added
[cm4]
dtoverlay=arducam_64mp
dtoverlay=arducam_64mp,cam0
Rebooted
but when I entered
libcamera-still --list-cameras
it found no cameras
Any help appreciated
