I never got the chance that I wanted to get this working (had to put out some other fires at work).  My weekend is booked, but I'm going to sit down Monday morning and tackle this.  Let us know how it goes for you, if you get to it this weekend.

Hi David,
How was your progress going with this? I really want to help but have not got around to it because I am in my senior year of UNI and it is pretty hectic. I will get on this over the weekend, if you have any area that I can help investigate I would be glad to.
Thanks,
Pete

You will find the answers on this forum but it's probably not "step by step".
I am away at the moment but can post a blow by blow description in the next
few days if that would help.

The basic idea is as follows:

1. You need to build the kernel under OE so you have the .config file the
build produces.

2. Copy over the .bb recipe for the kernel build and associated files into
user.collection (you are going to effectively edit the kernel build so you
don't want to mess up you base configuration).

3. Go into the directory where the previously built kernel .config  file
lives and do make ARCH=arm menuconfig.

4. follow through the steps exactly as for the documented buildroot approach
to reconfigure the kernel build to add the various drivers (pwc and V4l etc)
configured as modules.

5. Save the new configuration and copy the resulting .config file, replacing
the defconfig file in your kernel build files in user.collection.

6. Rebuild the kernel - bitbake -c rebuild gumstix-kernel.

7. This will give you a new kernel with the appropriate modules enabled and
a set of ipks with the pwc module and 4 ( I think) other modules that pwc
depends on.

8. Install the kernel and get your system running - then install the ipks.
The package manager will tell you in which order they are needed.

9. Once installed (I think the installer does a depmod - a automatically)
when you plug your camera in the module should load up and the camera would
be recognised. I don't think the system will create the /dev/video0 device
until then.

My system worked fine with the Philips spc900nc camera and can be used with
motion to put images on a webpage.
