I have been working with the C5515 ezDSP trying to implement a simple audio recorder. I can get all of the example SD record functions to work, as well as the Audio Filter demo which works. When I try to integrate the CSL MMCSD DMA example into this code, I run into some trouble.
First, I believe the Audio Filter demo may be using different versions of DMA than the CSL DMA calls. Is this correct?
Second, if I call just MMC_init();, the audio data stops streaming, but the code is otherwise running (LED normally turns on and off every 10 seconds).
Does anyone have a working version of a simple audio recorder for this board? It seems like something TI should offer to get people up running quickly. This forum seems to have a lot of people that have the same problem. My hope is that someone has cracked this nut and is willing to post their code.
