The code attempts to maintain a user format and a sensor format,
but in this case it looks like a typo is passing the user format down
to the sensor.
This was preventing display of video at anything other than 640x480.

For the ov7670 camera to return images at the requested frame rate,
it needs to make calculations based on the clock speed, which
it is dealing with. Work around this
problem by disabling RGB support. YUYV scaling works just fine.

Hi Jon,
We're dealing with a via-camera issue from the Scratch application.
The latest version of scratch uses libv4l2 and requests RGB24 images
as that is what it uses internally.
via-camera/ov7670 doesn't support RGB24 but libv4l2 kicks in with its
format conversion and chooses RGB565, which
This fixes autoloading of the module.

The QVGA mode has a green horizontal line on the left hand side, and a red

to remove them.

Hi,
The cafe_ccic + ov7670 combination is currently broken in mainstream

order to work on the new XO-1.5 laptop. The smbus IO code was brought
back in 467142093 but this code is never triggered - CONFIG_OLPC_XO_1
doesn't exist.

Yes. Applications like gstreamer will pick this resolution if its the

Hi Mauro,
Just a quick reminder about 4 pending cafe_ccic/ov7670 patches, all
acked by Jon Corbet:

This allows GStreamer to pick appropriate framerates and resolutions
based on desired capture parameters.
