Starterware: How do I get the I2S port on OMAPL138LCDK working?

Tool/software: Starterware

Hi

I am using the example mcasp_c674x_omapl138_lcdkOMAPL138 from starterware for OMAPL138. I see that in this example,  serializer 14/13 was used as DIN/DOUT. I want to interface it with the codec on TLV320AIC3106EVM board, I am wondering which serializer should I use, and how should I configure the code? (I changed it to 7/8 and configure TLV320AIC3016EVM according to the settings in this example project, but doesn't seem to work).
