Hi All,

I am working on custom SabreAI based custom board on android 7.1 platform.

This is our cs42888 codec section which is also based on reference design.

Screenshot from 2018-04-17 11_38_13.png

connected AOUT_1P connected to amplifier enabled speaker,and played audio but no audio is getting.

and also played using tinyplay but no result.connected cs42888 to i2c2

sound card is getting.

Hello,

I reviewing the schematic and the device tree. I have found that your configuration is a little different from our Sabre AI board. I suggest you have the configuration as is configured on our board. Otherwise, we cannot guarantee if it could work.

On the schematic, the only difference is that we have connected the ESAI_RST_B pin to a pull-up resistor. 

Regarding the device tree. I suggest you make the following configurations, this is how it is programmed our device tree.

i2c@021a4000 {
 #address-cells = <0x1>;
 #size-cells = <0x0>;
 compatible = "fsl,imx6q-i2c", "fsl,imx21-i2c";
 reg = <0x21a4000 0x4000>;
 interrupts = <0x0 0x25 0x4>;
 clocks = <0x3 0x7e>;
 status = "okay";
 clock-frequency = <0x186a0>;
 pinctrl-names = "default";
 pinctrl-0 = <0x30>;
        
        cs42888@48 {
  compatible = "cirrus,cs42888";
  reg = <0x48>;
  clocks = <0x33>;
  clock-names = "mclk";
  VA-supply = <0x34>;
  VD-supply = <0x34>;
  VLS-supply = <0x34>;
  VLC-supply = <0x34>;
  linux,phandle = <0x50>;
  phandle = <0x50>;
  };


regulator@2 {
 compatible = "regulator-fixed";
 reg = <0x2>;
 regulator-name = "cs42888_supply";
 regulator-min-microvolt = <0x325aa0>;
 regulator-max-microvolt = <0x325aa0>;
 regulator-always-on;
 linux,phandle = <0x34>;
 phandle = <0x34>;
};

sound-cs42888 {
 compatible = "fsl,imx6-sabreauto-cs42888", "fsl,imx-audio-cs42888";
 model = "imx-cs42888";
 esai-controller = <0x4e>;
 asrc-controller = <0x4f>;
 audio-codec = <0x50>;
};

Hope this information could help you.

Best regards,

Diego.

Hi diegoadrian,

Thank you for your response.

Can you share complete device tree of the same mx6qdl-sabreauto.dtsi

Regards,

Richu
