PCM5242: Need support to bring-up PCM5242codec with IMX8MM with Android 11 code

Please find below logs:

Hi Team,

PLease find below update:

above issue is solved.

Need your help to bring-up one Audio DAC PCM5242.

We are using PCM5242 DAC with IMX8MM NXP processor.

So far I have added dtsi and driver changes. But not getting any sound from speaker.

Changes:

        sound-pcm5242 {

               compatible = "simple-audio-card";

               simple-audio-card,name = "pcm5242_50w";

               simple-audio-card,format = "i2s";

               simple-audio-card,bitclock-master = <&dailink0_master4>;

               simple-audio-card,frame-master = <&dailink0_master4>;

               simple-audio-card,widgets =

                        "Line", "Left Line Out Jack",

                        "Line", "Right Line Out Jack";

               simple-audio-card,routing =

                        "Left Line Out Jack", "OUTL",

                        "Right Line Out Jack", "OUTR";

               dailink0_master4: simple-audio-card,cpu {

                       sound-dai = <&sai5>;

               };

               simple-audio-card,codec {

                       sound-dai = <&pcm5242>;

                       clocks = <&clk IMX8MM_CLK_SAI5_ROOT>;

               };

       };

        pcm5242: pcm5242@4c {

                compatible = "ti,pcm5242";

                #sound-dai-cells = <0>;

                reg = <0x4c>;

                AVDD-supply = <&reg_3p3v>;

                DVDD-supply = <&reg_3p3v>;

                CPVDD-supply = <&reg_3p3v>;

                clocks = <&ext_osc_22m>, <&ext_osc_24m>;

                clock-names = "sclk0", "sclk1";

        };

I2C dump:

1. When audio is not playing:

1. When Audio is playing:

Sound controls:

OUTPUT:

All the I2S clocks are proper as expected , DIN data also present.

But no audio output from speaker.

Divyesh,

I will take a look at this post tomorrow as I am wrapping up some other task in the queue.

Hi Arash Loloee,

Thanks for the reply.

I need close this by Thursday. It would be helpful if you ask someone to look into this.

Sorry for the inconvenience. But its urgent. On Friday I have release the build with customer.

Thanks

I think I  will be able to close it by Thursday , if not i will ask  another engineer to look at this post .

Regards,

Arash

Thanks.. Looking forward to your response

Hi @Arash Loloee,

Just for the info, We are using below driver for PCM5242:

modified: arch/arm64/boot/dts/freescale/imx8mm-evk.dtsi
modified: arch/arm64/configs/imx_v8_android_defconfig
modified: sound/soc/codecs/pcm512x-i2c.c
modified: sound/soc/codecs/pcm512x.c

Thanks

Hi Divyesh,  here is all the drivers that we can offer:

e2e.ti.com/.../faq-linux-drivers-device-drivers-for-aic31xx-dac31xx-aic325x-aic320x-aic326x-aic321x

Could you verify  the register dump when you are playing audio and have no Audio output . The part is not in standby or mute by any chance?

Regards,

Arash

Hi Arash

If you check my earlier comment, I have shared i2cdump when playing audio and without audio. Could you please have a look once.

Regarding driver, Im using driver from similar family PCM5142.  Both the ic's are having same register map.

Thanks

Divyesh

Hi Divyesh,  in the register dump,  when Audio is not playing , we see register 3 has  11 which is MUTE left & Right channels. Also Register 2 is 11 which is powerdown/standby.  That is why I asked to check and make sure registers read is correct. Based on your register dump, you are muting and powering down the device and thus there will be no audio playing.

Arash

Hi Arash,

When the audio is not playing, which means device will be in standby and mute only.. it seems correct..

Have you checked register dump when audio is playing? 

I can see logs from mute and unmute function properly when I try to play something. But not sure it is reflecting properly or not in register map.

Thanks

Hi Divyesh,

May be we are talking about 2 different things. When you say "Audio is not playing"  we read it as "you want to play audio but it is not playing". In this condition  we read its register dump and we see it is muted ( and DAC is in power down too) . I guess you mean the issue is in the other register dump.

I can run a simple test with our EVM and then get the register dump to you so you can compare it with yours and see what is written in your registers that makes it not working. 

Let me know if this is something that you want.

Regards,

Arash

Hi Arash,

Yes.

Audio is not playing means ideal case when device boot up.(didn't try to play audio)

Audio is playing means when we try to play audio using tinyplay or media player.

Please share the working register dump

I need your quick response today. I need to close it by today. 

Thanks

Divyesh
