RT1052 SAI and EDMA --- Dual Buffer Audio DMA

I need a demo of dual buffer audio DMA. I noticed AN12090, which talks exactly what I need. But unfortunately, it seems like that AN12090 is an incomplete document. Dual buffer audio dma (ping pong buffer) needs a lot of DMA configurations. This document deosn't mention it at all.

 

So, does anybody know if there is the demo code for AN12090, and where to get it?
