Reloading SDMA parameters

Other Parts Discussed in Thread: OMAP3530

Hello,

Currently I am using the SDMA module on ARM in OMAP3530. I am using the "link" feature of SDMA where in one DMA channel can be linked to another. My question is:

I want to alternate the successive DMA transfers between two destination buffers. Is it possible to reload the DMA parameters after a DMA transfer?

Your inputs regarding this would be helpful.

Thanks.

Regards,

Hi Divya,

I am working on OMAP4 processor based pandaboard. I have successfully booted the board with Ubuntu 11.04 netbook image. Now I want to enable DMA for both ARM and DSP. I have found some sites which contains dma.c file with the necessary header files. the links are:
http://tomoyo.sourceforge.jp/cgi-bin/lxr/source/arch/arm/plat-omap/dma.c //see line 14
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=bl...

But I don't know where to copy these files and how to run them. Is
there any package available which will directly install these files
into the relevant directories?

Thanks & Regards,
Rahul Agarwal
