Dear I.MX Community,


I found out that in I.MX28 BSP on I.MX28 EVK, that SAIF1_SDATA0 is configured as input, But in my custom board, I require two playbacks ie, SAIF0_SDATA0 & SAIF1_SDATA0 to be configured as output, As in I.MX28 BSP ie., L2.6.35_10.12.01_ER_source SAIF0_SDATA0 is already configured as output, & am able to do the playback on SAIF0_DATA0


So could you anybody please confirm, if I configure SAIF1_SDATA0 as scr &= ~BM_SAIF_CTRL_READ_MODE; in Mxs-dai.c is that sufficient inorder to do the other playback or any other configuration needs to be done apart from this,


Could you please provide me the test application inorder to play a .wav file through /dev/snd/pcmC0D0p (SAIF0_SDATA0) instead of alsa utilites ie., aplay for one playback & /dev/snd/pcmC1D0p for the other playback, , kindly do the needful as early as possible



Many Mant thanks in advance
