CCS/OMAPL138B-EP: Audio input to output loopback example project for the OMAPL138 evaluation board

Part Number:OMAPL138B-EP

Tool/software: Code Composer Studio

Hi. 

1. I want to purchase the OMAPL138. Before that, I would like to be able to build a simple project that simply takes each input frame (one by one, no buffers) and output it to the D2A.

Is there such an example project I can use?

2. I am trying to build the mcasp example from the StarterWare. However, I get a build error saying:

"../edma.c", line 117: error: identifier "SOC_EDMA3_NUM_DMACH" is undefined

besides that, this example's code is pretty long and I think it uses buffers ( I want it to be realtime one by one, no buffers are needed).

I think a few lines of code should be enough to redirect the input into the output...

Thanks.
