[ros-users] call for testing: camera1394 in C-turtle

I'm trying to use camera1394 with a Point Grey Chameleon on Ubuntu
10.04 on a beagleboard-xm. I am having troubles -- it's an alignment
exception of some kind. Has anyone tried running camera1394 on
armel/beagleboard-xm before? I attached a picture showing the current
state of affairs. In terms of the version of camera1394, I just
pulled the CTurtle base stuff from SVN last night and built everything
on my beagleboard-xm. Offtopic but funny -- the camera uses more
power than the whole beagleboard running Ubuntu! :)
