Hi Digant,
Yes it's pretty much I/O AT specific. The PL081 has a lot more features than the I/O AT one. What are you trying to use the dma engine for anyway? The I/O AT dma engine and the PL081 are significantly different and thus substantial modifications would be required.

Do I need to develop something for ARM ? Can I use the same state machine with little modifications ?

I believe that the PL081 is significantly more complicated. The documentation for the PL081 can be found at: http://infocenter.arm.com/help/topic/com.arm.doc.ddi0218e/index.html [2] Thanks, Ali On Wed, 30 Mar 2011 14:39:00 -0700, Digant wrote: Ali, I would love to work on it, Can you suggest me any good starting point ?

I tried using it on ARM_FS but I couldn't. Is there any way I can do DMA operations on ARM ? Thank you.
