Hello Community!


In the IMX6SDLRM,there are descriptions as bellow:


In I2S slave mode(SSI_SCR[6:5]=10), the following settings are internally overridden by

the hardware:

. Normal mode is selected (SSI_SCR[3]=0)



I am using L3.0.35_4.1.0 and I have not touched the SSI related drivers.When it is playing audio, I read the value of SSI1_SCR(addr:0x2028010),the value is 0x15F.

That is in I2S slave mode(SSI_SCR[6:5]=10), the Normal mode is selected (SSI_SCR[3]=1).


My questions are:


why SSI_SCR[3] is not internally overridden by the hardware.



Whether should I change  the imx-ssi.c to set the SSI_SCR[3] to 0?


Thank you!

Best Regards!
