Hello Emmanuel,

Please check the sai_dma_demo example that is located at the below path after install MQX 4.1.

C:\Freescale\Freescale_MQX_4_1\mqx\examples\sai_dma_demo\build\ds5

This example shows the use of the DMA driven SAI driver.

Regards

Sol

You're right, DMA API is shown in the SAI driver.

Unfortunately, the MQX 4.1 it's not available yet with Timesys environment, I tried it, but it seems to have some conflicts with DMA linux driver (UART console driver stops).
