Hello,everyone:
     I have a question and I need your help.
     It's about DMA of DaVinci platform. As we know,
the DMA Driver has been impletmented on the DaVinci
platform . But I don't know how to use it . For
example, I can use open ,read, write, close to read or
write an AUDIO device, but how should I do to read or
write an AUDIO device using DMA ?  This is the first
question.
     And this is a second question . If I want to copy
 date from a block of memory to another block of
memory ,I usually use memcpy() to finish it.But how
should I do if I want to do it using DMA? 
     Thanks!
