I followed the steps in
with a brand new and updated installation of Pi OS 64bit (Bullsey) and the 16MP AutoFocus Camera.
It says to
Step 4. Install Camera drivers
Preview 5 seconds.
libcamera-still -t 5000
When I just follow the steps then in step 5, I get an error about “no camera detected”.
A reboot fixed it.
Maybe add that as another step to the page?
