Hi Andrew,

Thanks very much for the detailed reply and the links, this is really helpful. I had come across Scott's instructions but wasn't sure if this was the best way to go.

Interesting observation about the USB cameras.

This all helps - thanks. Good luck with your project too.

John

Hi John,

I have a similar setup (FireSTORM with caspa).  I was able to build a 2.6.34
console image that used the DSP to compress video captured from the caspa
and stream it over the network.  I did it a while ago but I remember it
wasn't too difficult using the extremely helpful instructions at
http://www.jumpnowtek.com/index.php?option=com_content&view=article&id=81:gumstix-dsp-gstreamer&catid=35:gumstix&Itemid=67
jumpnow .

Lately however, I needed to use a newer kernel (2.6.39) because the old one
didn't support the Robovero (cdc_acm module has a problem with it).
Therefore, I needed to rebuild everything.  Getting the DSP to work wasn't
too bad, it was just a matter of changing PREFERED_VERSION_ti-linuxutils
http://gumstix.8.n6.nabble.com/Using-TI-DSP-link-with-3-0-0-kernel-td4626788.html
Kernel Patching .  I didn't play around with the instructions for patching
the kernel for the caspa because for my application that extremely short
ribbon cable just won't cut it.  There's been some discussion on here about
using a longer cable but with varying success.  I've decided to go with USB
cameras.  They're supported right out of the box.  They seem to use more CPU
time to do the same thing as the caspa but their versatility far outweighs
the negatives.

My suggestion would be to get yourself up and running with OpenEmbedded
http://gumstix.org/software-development/open-embedded/61-using-the-open-embedded-build-system.html
Gumstix - OpenEmbedded , checkout the Jumpnow website I posted above (but by
now you've probably been there).  Follow Scott's instructions there and
build yourself a 2.6.34 kernel.  If you can stick with 2.6.34 that would
probably be the easiest thing to do because his instructions are pretty
extensive and should get you up and rolling.

Hope this helps, good luck.

Andrew
