FRDM-K64F SAI fails to transmit (example project)

I have attached a very simple PX KDSK1.3 project with only an SAI module added, which blocks during initialization on a call to SAI_DRV_TxSetIntCmd due to a continuously firing ISR. The call to SAI_DRV_SendDataDma in main never happens.

 

What would really help is a working example of double-buffered (largest buffer possible) I2S master receive and transmit via eDMA, which might also resolve Here's an example for using SAI w/EDMA without the SND API (K22)..

 

Thanks,

Jake
