McBSP+DMA config

Other Parts Discussed in Thread: OMAP3530

Hello everybody;

      I am new on OMAP3530 and i am Beagleboard. What i try to do is getting encoded video as data from expansion header of the bb

through McBSP and using DMA because our data will be big. Then we will write it onto disk. Until now, i try to investigate on source codes and 

Paul's loopback implementation. Loopback was actually useful for me but three question i had. 

1- How can i use DMA with McBSP

2- How can i say to that McBSP take the from expansion header

3- After taking data how can i write it into smting as disk.

 

Thank in advance
