It is possible the ipipe kernel hasn't been ported properly to this target. Check the gpio driver and irq chip driver and the timer driver to see if they have any ipipe related code. It's possible this target was supported by older ipipe versions but wasn't fully ported to a recent version of the ipipe. I'll check tonight when I get a chance to confirm if this target has support. -Greg
