TAS2563QFNEVM: TAS2563: TAS2563 integration on linux kernel 6.12 with IMX95

Hi Shenghao Ding,

Thanks for connecting and apologies for the confusion. 
The chip used is TAS2563.

Can you confirm the usage of the following patch which was shared by TI in another forum where kernel version used was 6.6.x.
e2e.ti.com/.../tas2563-tas2563-integrated-on-linux-kernel-6-6-with-imx95-driver-got-loaded-card-detected-in-aplay-but-the-48khz-wav-files-are-not-runnig

"tas2781-audio-codec.patch"

This patch has changes related to following files
1. include/sound/tas2781-comlib-i2c.h
2. include/sound/tas2781-dsp.h
3. include/sound/tas2x20-tlv.h
4. include/sound/tas5825-tlv.h
5. sound/soc/codecs/tas2781-comlib-i2c.c
6. sound/soc/codecs/tas2781-comlib.c
7. sound/soc/codecs/tas2781-fmwlib.c
8. sound/soc/codecs/tas2781-i2c.c

And also found below set configs are added 
+CONFIG_SND_SOC_TAS2781_COMLIB=y
+CONFIG_SND_SOC_TAS2781_COMLIB_I2C=y
+CONFIG_SND_SOC_TAS2781_FMWLIB=y
+CONFIG_SND_SOC_TAS2781_I2C=y

Some of the above files are available in 6.12, but the contents are exactly same as defined in the patch.

Can you suggest is there anything's to be picked from this patch and what configs to be enabled for bringing and making TAS2563 functional?

You can sue the code in kernel 6.12 directly.

In kernel 6.12, no CONFIG_SND_SOC_TAS2781_COMLIB_I2C, so you won't care that.

What you do is to register the sound card in your platform. If you have issue, you can consultant the platform vendor. They have many examples to register third-party audio amplifier. Good luck.

Without adding any patch and only device tree changes to add TAS2563 is getting the probe error.

localhost:~$ dmesg | grep -i "tas2563"
[ 21.743068] platform sound-tas2563: deferred probe pending: asoc-simple-card: parse error

Below are the dts changes.

sound-tas2563 {
compatible = "simple-audio-card";
simple-audio-card,name = "tas2563";
simple-audio-card,format = "i2s";
simple-audio-card,frame-master = <&cpu_dai>;
simple-audio-card,bitclock-master = <&cpu_dai>;
simple-audio-card,widgets =
"Speaker", "SPK";
simple-audio-card,routing =
"ASI", "SPK",
"SPK", "OUT",
"DMIC", "ASI OUT";
cpu_dai: simple-audio-card,cpu {
sound-dai = <&sai3>;
dai-tdm-slot-num = <1>;
dai-tdm-slot-width = <16>;
};

codec_dai: simple-audio-card,codec {
sound-dai = <&audio_amp>;
};
};

audio_amp: tas2563@4c {
compatible = "ti,tas2563";
reg = <0x4c>;
#sound-dai-cells = <0>;

reset-gpio = <&gpio_expander 0 GPIO_ACTIVE_HIGH>;

clocks = <&scmi_clk IMX95_CLK_SAI3>;
clock-names = "mclk";

vdd-supply = <&reg_3p3v>;
iovdd-supply = <&reg_1p8v>;
};

I am taking the same DTS changes which able to detect/probe the TAS2563 with kernel 6.6.

I confirm no changes in the hardware base board, but only latest version of i.MX95 SOC from NXP is used, which basically supports minimum kernel version 6.12.

So I am here trying to port from kernel 6.6.x to 6.12.x

Why not consult the platform vendor on the DTS setting?

Do you mean the same dts setting work in kernel 6.6?

Yes, can you confirm what reg addr to use?
It is reg = <0x4c>; or reg = <0x48>; ?

In i2c probe I see both getting detected but unused.

localhost:~$ sudo i2cdetect -y 3

localhost:~$

Ok, then can you guide on resolving deferred probe error.
What is the config's which are much required to bring up the TAS2563.
Apart from the data sheet, is there any application note kind of a document to guide the integration relative to latest kernel versions.

Hi Ding
I am able resolve the probe error and could read TAS2563 sound card from aplay -l

localhost:~$ aplay -l

The logs from the dmesg describes:
tasdev-codec 3-004c: Direct firmware load for tas2563RCA1.bin failed with error -2
tasdev-codec 3-004c: Falling back to sysfs fallback for: tas2563RCA1.bin
tasdev-codec 3-004c: Failed to read tas2563RCA1.bin


Can I get the binary "tas2563RCA1.bin" ?

Hi Shenghao,
Thanks for sharing the tas2563RCA1.bin file. Post having the tas2563RCA1.bin in the "/lib/firmware", I see the following from dmesg log.

tasdev-codec 3-004c: Direct firmware load for tas2563_coef.bin failed with error -2
tasdev-codec 3-004c: Falling back to sysfs fallback for: tas2563_coef.bin

I'm not sure is this dependency blocking the TAS2562 functionality, because I am trying to record the audio file with .wav extension and didn't encounter any failures or errors in the process, but when I try to play the recorded audio file from the windows machine, I can't hear out any voice note/ audio from the wav file.

Below is the procedure followed.

Recording WAVE 'test_2_koala.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

I'm using the above PDM microphone make

Hi guy

1) type amixer in your system, I will check whether the RCA file has been load properly first.

2) share the playback command you used.

3) also share the wav file you playback with me

As to coef.bin, have you used PPC3 tool to generated bin file for PDM recording?

Hi

Please find the inline response.

1) type amixer in your system, I will check whether the RCA file has been load properly first.

localhost:/$ amixer
Simple mixer control 'Speaker Digital',0
Capabilities: volume volume-joined
Playback channels: Mono
Capture channels: Mono
Limits: 0 - 255
Mono: 243 [95%] [0.00dB]
Simple mixer control 'Speaker Force Firmware Load',0
Capabilities: pswitch pswitch-joined
Playback channels: Mono
Mono: Playback [off]
Simple mixer control 'Speaker Profile Id',0
Capabilities: volume volume-joined
Playback channels: Mono
Capture channels: Mono
Limits: 0 - 10
Mono: 0 [0%]

2) share the playback command you used.
I am not using playback (aplay here) as I don't have speakers at this moment to connect TAS2563.

My purpose is to record the audio file (.wav) and move it to windows laptop to verify using media player.

3) also share the wav file you playback with me




4) As to coef.bin, have you used PPC3 tool to generated bin file for PDM recording?

No, I haven't used PPC3 tool

Thanks for confirming. Can you help me to find the "tas2563_coef.bin" or how to generate one if required?

Let me transfer your request to your TAS2563 expert.

My amixer controls outputs only related to speaker related controls but nothing related to PDM microphone.

localhost:/$ amixer controls
numid=1,iface=MIXER,name='Speaker Digital Volume'
numid=2,iface=MIXER,name='Speaker Force Firmware Load'
numid=3,iface=MIXER,name='Speaker Profile Id'

Am I missing PDM related things here.

In one of the readme file I see below things mentioned. 

PDM ON/OFF feature:
Before runing aplay&arecord, run following command to turn on PDM
amixer cset numid=6,iface=MIXER,name='Pdm switch Ctrl' 1
Before runing aplay&arecord, run following command to turn off PDM
amixer cset numid=6,iface=MIXER,name='Pdm switch Ctrl' 0


But in my scenario I don't see the PDM related controls.

Can you help me with these changes and generate a RCA bin file for me.
Sorry I making this request because I haven't used this tool before and I might need some time to get used to it.
Also we are planning for a Proof of concept demo for the TAS2563 use case which is scheduled tomorrow.

in your bin file, it has already contained that setting.

Simple mixer control 'Speaker Profile Id',0
Capabilities: volume volume-joined
Playback channels: Mono
Capture channels: Mono
Limits: 0 - 10
Mono: 0 [0%]

The key word "Limits" means the profile 0 ~ 10.

Hi Shenghao,

Can I get tas2563_coef.bin file ?

Sorry, I have no coef.bin for PDM. Please Let us now what's the trouble with the PDM making?
