I have a doubt in DMA transfer, After complettion of DMA transfer is the Destnatin and source addresses increments by element index or they remains same..?

Im working on OMAP2430. I have to do DMA in my project.
Are there any examples related to DMA?
Pls give me some pointers.

It looks like a synchronisation problem.
You need to use double buffers or ping pong buffers. otherwise you get problem when IRQ and DMA try to access the same space.
