Can internal RAM be used for DMA transfer in iMX35?

I want to use IRAM for the transfering audio data over iMX35 MediaLB port to the INIC OS81050 using synchronous channel.

But when I use IRAM for buffering the audio data, I get only the noise. I suspect the problem could be because of using the internal RAM.


The reason I suspect IRAM being, I dont see any problem when the use EMI memory for the same pusrpose.


I would really appreciate any kind of help fpr this problem I am facing.


Thanks in Advance.
