I did the initial patchset for 2.6.24 to support an SPI feature which ended up
being the basis of the 2.6.24 code in the Gumstix OE tree. I'm tempted to do
the same for 2.6.26 to get the new LED driver infrastructure. If I've got time
over the next couple of weeks I'll have a stab at it.

I'm really keen to get this going.  I've tried applying the patches from
2.6.24 but they don't apply cleanly - too much has changed and I don't
understand what each patch does.  Is there documentation anywhere that would
help me update the patches?

I've revised the patches for 2.6.26 but have only just started testing them.
Connex seems to work but I haven't tested all the hardware yet. I'll flash a
Verdex today to make sure it boots; if so I'll send the patches to Steve so
other people can test them.

With this Patch set can I make the OV9650 camera work with Quick capture on
Linux 2.6.24 ?

I really need to make this work.

Harry, that's fantastic, can't wait to help testing and begin working on
Quick Capture again!  So does Steve place the patches into the OpenEmbedded
distribution on gumstix SVN?

Demetris, it contains only the basics for using Quick Capture hardware to
grab frames with Video4Linux software.  Currently the only camera chips
supported on Quick Capture in 2.6.26 are Micron MT9M001 and MT9V022, but
like I said I'll be writing a driver for an OmniVision very soon (OV7620 and
possibly OV10620 if I can get my hands on one).  If you haven't already,
follow
http://www.gumstix.net/Software/view/Getting-started/Quick-start/111.html 
It compiles 2.6.21 but as soon as the patches are available we'll be able to
replace it with 2.6.26  :^)

Here's both good and bad news, there's already a driver written for OV9655
but OV has not yet allowed it to be released because the developer signed a

Can't I just write an App to read the camera with the GPIO's and assemble
the image in OpenCV ?

Do I really need all this hustle to get an image from the camera?

Anyway, I think I'll write a simple App in GTK to capture and save images
for the OV9650.

Any progress on this? I would be happy test anything on my verdex :)

Did the verdex board boot up, Harry?  I would love to be able to test out
the 2.6.26 build to see how it goes.  Same question as above though, will
those patches just make their way to the OE svn?

As for the driver development on the OmniVision sensors, I sent an email to
them about the NDA and releasing drivers.  Their response was "As long as
the settings and the data sheet are not included or to be viewed by any
customer, that should be ok".  Seeing as all the settings are done through
the SCCB (I2C) interface and are different for different applications
anyway, I figure this means we can share the the driver information (minus
I2C setup).

I was looking through the forums and found this thread about the Quick
Capture on the Gumstix.  I'm trying to find a way to get an NTSC video
signal onto the gumstix, and thought that this might be a way of doing it. 
Does anyone know what became of this project and whether anyone got the
quick capture interface to work succsesfully?  Thanks.
