Hello, AEs:

      We use the SAI interface to connect an LMX2571, we want to send data to LMX2571 through this interface, like SPI or Uart drivers, open a device, call IOCTL command to configure I2S, and then send data. Is there any way to support this? I am not familiar with the audio architecture, and out project is very urgent, I hope to get your effective support. thanks.

Hi 国承 张 

one can look at non-linux SAI MX6ULL  FreeRTOS  SDK examples below

and develop own SAI interface, using SPI or Uart drivers IOCTLs as examples:
