Hi all,

 

I would like to ask about SDMA of i.MX6.

My customer wants to use SDMA with SSI as below.

(1)

DMA transferring from Buffer1(memory) to SSI with specific data size.

(2)

Continuously to completion of (1), start DMA transferring from Buffer2(memory) to SSI with specific data size.

(3)

Continuously to completion of (2), Back to (1).

The customer believes that continuous data transfer to SSI will be achieved by the above procedure.

Is it possible to use SDMA of i.MX6 as above?

Is yes, please let me know how one can handle SDMA for that.

 

Thanks,

Miyamoto
