External audio codec TLV320AIC3254 interface with IMX7D using SAI3 interface

[PotturuVenkataPrasad]

HI,

We are trying to interface TLV320AIC3254 audio codec with Colibri IMX7D module using SAI3 interface.

And we want to configure codec as slave, it means that processor should give all the clocks MCLK, BCLK and WCLK. In my case we are getting mclk as 24MHz and no BCLK and WCLK.

What should we do to get the BCLK and WCLK from processor, please have a look at below nodes of the dts file and let us know any changes required and help us to get the clocks.

Hi,

&sai3 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_sai3 &pinctrl_sai3_mclk>;
assigned-clocks = <&clks IMX7D_SAI3_ROOT_SRC>,
<&clks IMX7D_SAI3_ROOT_CLK>;
assigned-clock-parents = <&clks IMX7D_PLL_AUDIO_POST_DIV>;
//assigned-clock-rates = <0>, <36864000>;
status = "okay";
};

36864000 is SAI3 ROOT CLOCK, you shouldn't comment it.

Have a nice day!

B.R,

Hi,

We tried as you suggested, but still we not getting BCLK and WCLK.

What we need to do to get the clocks. Kindly suggest a solution for this.

Thanks & Regards,
