hello all, I am using c5409 based board in the development environment. I have connected PCM3008 with McBSP of c5409. I have programmed the McBSP such that, Recevie/Transmit Frame Length is 2 words per frame and Receive/Transmit Word Length is 32-bits. When I program like this, the Left and Right channel data are getting interchanged. Without DMA, I am able to solve that issue, by changing the data address inside the ISR. When I interface the McBSP with DMA, I problem still exists. How should I configure the Receive and Transmit DMA? (I want a DMA setting something like this, If I receive Frame0, Frame1..., this should be stored as Frame1, Frame0,Frame3, Frame2... ). Regards, kans. __________________________________ |
