DSP + opencv


I have developped a little opencv application which display a camera.
But performance don't seem to be enough because i am loosing some
frames. I am working on devkit8000 board.

I have found that dsplinkk.ko could not be loaded because of invalid
format. I think it's because i haven't the right linux. I have 2.6.28
from devkit8000 CD and angstrom need 2.6.32.

1) Where can i find linux 2.6.32 for devkit8000 ?
2) Why do i have message : invalid format ?
