hi. LaoHuo

   both of these wiki are updated by Felipe recently, so, if you have
any problems, just post at here. someone may give you help.

   I remember that, at first, or at least, you must have compiled you
kernel dsp-bridge module. you can get the kernel which has dsp-bridge
module from http://github.com/felipec/linux-omap .

  and please read threads following:
