Codec SGTL5000 can not work

Hi Community,

I'm working on i.MX6 Quad sabre-SD and build Android 6.0 for my image.

I'm trying to porting codec sgtl5000 on my self designed platform.

In menuconfig I enabled following settings:

CONFIG_SND_SOC_IMX_SGTL5000=y

CONFIG_SND_SOC_SGTL5000=y

In boot/dts/FX100_DEV.dtsi I set following settings:

sound {
compatible = "fsl,imx6q-nitrogen6x-sgtl5000",
"fsl,imx-audio-sgtl5000";
model = "fsl,imx-audio-sgtl5000";
ssi-controller = <&ssi2>;
audio-codec = <&codec>;
audio-routing =
"MIC_IN", "Mic Jack",
"Mic Jack", "Mic Bias",
"Line Out Jack", "Line In Jack";
mux-int-port = <2>;
mux-ext-port = <3>;
mic-det-gpios = <&gpio1 9 1>;
};
&ssi2 {
status = "okay";
};
&i2c1 {
   clock-frequency = <100000>;
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_i2c1>;
   status = "okay";
   codec: sgtl5000@0a {
      compatible = "fsl,sgtl5000";
      reg = <0x0a>;
      clocks = <&clks 201>;
      VDDA-supply = <&reg_2p5v>;
      VDDIO-supply = <&reg_3p3v>;
   };
};
&audmux {
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_audmux>;
   status = "okay";
};
&iomuxc {
   pinctrl-names = "default";
   pinctrl-0 = <&pinctrl_hog>;
   pinctrl_hog: hoggrp {
      fsl,pins = <
      /   * SGTL5000 sys_mclk */
      MX6QDL_PAD_GPIO_0__CCM_CLKO1 0x030b0
      >;
   };
   pinctrl_audmux: audmuxgrp {
      fsl,pins = <
         MX6QDL_PAD_CSI0_DAT7__AUD3_RXD 0x130b0
         MX6QDL_PAD_CSI0_DAT4__AUD3_TXC 0x130b0
         MX6QDL_PAD_CSI0_DAT5__AUD3_TXD 0x110b0
         MX6QDL_PAD_CSI0_DAT6__AUD3_TXFS 0x130b0
      >;
   };
};

After all this settings, I still can not broadcast my music.

My line out and line in can not work.

What else did I miss?

Is my dtsi settings wrong?

Thanks in Advanced!

Hi tsung

sgtl5000 is used on boundary devices and one can look at its dts example

linux-imx6/imx6qdl-sabrelite.dtsi at boundary-imx_4.1.15_2.0.0_ga · boundarydevices/linux-imx6 · GitHub

GitHub - boundarydevices/linux-imx6 at boundary-imx-m6.0.1_1.0.0-ga

Audio output selection under Linux on i.MX6 - Boundary Devices

Hi igorpadykov‌

boundary device did not set Line In and Line Out.

I can not take this as reference.

Is there any additional suggestion?

Re: Codec SGTL5000 can not work

you can verify sgtl5000 settings with i.MX6Q baremetal sdk found on

SMP Enable in IMX6

then compare them in linux.

Hi igorpadykov‌

Now I can play music.wav by command "tinyplay".

Cause this result I can sure that my driver and hardware design is correct.

But I get a new issue.

When I use Android default Music player to play Music.wav, It would show "not support this type".

Even I tried to play other type of music such as mp3, it still show the same error.

And I had found out that under path "hardware/imx/alsa" has no sgtl5000.h supported in HAL.

Is NXP has sgtl5000 patch on HAL、 JNI or all the upper layer that sgtl5000 woule need?

nxp does not support sgtl5000 for i.mx6 bsps and has not patches for it.

Hi igorpadykov‌

Thanks for your reply.

I think I should ask codec agent for it?

Hi igorpadykov

Thanks for your previous support.

I've found solution.

There are many codecs that freescale had supported in path hardware/imx/alsa/ .

But like you said freescale BSP did not support SGTL5000 in HAL.

So I found a link that said "how to add a new codec in Android BSP" showed as below.

How to port new audio codec into Android.docx

This file will teach you how to design a header file for your codec and modify some place in tinyalsa_hal.c .

After all this work, my codec can play in Android system and even playback via command "tinyplay" with format mp3、wav、mp4 and so on...

Wish can help other people who is struggled with new codec that Freescale patch does not support.
