I have just tried the camera and sensor again , this time on the bench,
and now I am getting:
mmal: Cannot read camera info, keeping the defaults for OV5647
Then a bit further down it says:
mmal: Camera is not detected.

So basically the camera is kaput?

It's weird how one day it was working fine then another day not at all.

Oh well , C'est la vie
