IMX8DX SAI2 MASTER MODE

[afridi20]

Hi NXP team,                                                                                                                                                                                                                                                                                                                              In IMX8DX SAI0/SAI1 interface as master mode, SAI0/SAI1 can able to produce the clock  to slave device while it is used for both playback and capture operations. TXC and TXFS pinouts of SAI0 are able to generate bit clock and frame sync clock. But SAI2/SAI3 cannot able to generate while it is configured in master mode. Is it possible to use SAI2 as a master and generate bit/frame sync clock for other slave device like FM module? The data sheet shows SAI2 is receive only and contains pinmux as ADMA_SAI2_RXC, ADMA_SAI2_RXD and ADMA_SAI2_RXFS. Kindly help on this issue and comment whether clock generation is possible in SAI2/SAI3 pins.

Recommend you to use the SAI0/1, As you can see in our RM that SAI0 and SAI1 are transmit/receive; SAI2 and SAI3 are receive only.
