TLV320AIC3111: What should be CODEC input and outputs for TLV320AIC3111 for device tree AM62 (SK AM62)

Mitesh Hiran

Part Number: LINUXSDK-OMAPL138
Other Parts Discussed in Thread: SK-AM62, TLV320AIC3111, TLV320AIC3106, AM625, PCMD3140, TLV320AIC3262

Hello, I have modified the SK-AM62 eval board and connected to the TLV320AIC3111EVM board to test the functionality on Linux.

I have installed the default SDK (08.06.00.42) and flashed the Linux kernel and can test that the default audio codec on the SK-AM62 works and now have started to modify the device tree to support TLV320AIC3111.

Can you let me know what should be the codec inputs and outputs for TLV320AIC3111 please?

Hi Guy

I want to confirm from you that, your project plan to one simple audio card connect two different codecs, am I right?

Are the two codecs connected on i2c?

Hi,

we have removed all the 0 Ohm resistors (related to audio codec) and connected the new codec TLV320AIC3111 to the AM625 processor.

Will Audio Codec TLV320AIC3111 work with both TLV320AIC3x and TLV320AIC31xx drivers ?

I see both these options in menuconfig.

Here is the example on how to register two audio device into the simple audio card. Hope this can help you well.

&i2c0 {
tda19988: tda19988@70 {
compatible = "nxp,tda998x";
reg = <0x70>;
nxp,calib-gpios = <&gpio1 25 0>;
interrupts-extended = <&gpio1 25 IRQ_TYPE_LEVEL_LOW>;

pinctrl-names = "default", "off";
pinctrl-0 = <&nxp_hdmi_bonelt_pins>;
pinctrl-1 = <&nxp_hdmi_bonelt_off_pins>;

/* Convert 24bit BGR to RGB, e.g. cross red and blue wiring */
/* video-ports = <0x234501>; */

#sound-dai-cells = <0>;
audio-ports = < TDA998x_I2S 0x03>;

ports {
port@0 {
hdmi_0: endpoint@0 {
remote-endpoint = <&lcdc_0>;
};
};
};
};
};

&i2c2 {
#address-cells=<1>;
#size-cells=<0>;
pcmdevice: pcmdevice@48 {
compatible = "ti,pcmd3140";
#sound-dai-cells = <0>;
reg = <0x48>;
};
};

sound {
compatible = "simple-audio-card";
simple-audio-card,name = "TI BeagleBone Black";
simple-audio-card,dai-link@0 {
format = "i2s";
bitclock-master = <&dailink0_master>;
frame-master = <&dailink0_master>;

dailink0_master: cpu {
sound-dai = <&mcasp0>;
clocks = <&clk_mcasp0>;
};

codec {
sound-dai = <&tda19988>;
};
};
simple-audio-card,dai-link@1 {
format = "i2s";
bitclock-master = <&sound0_1_master>;
frame-master = <&sound0_1_master>;

I have disconnected on board audio codec (TLV320AIC3106) and now I have connected TLV320AIC3111 EVM to this interface with I2C bus. but when rebuild the kernel and search for sound card says none found.

0 Mitesh Hiran over 2 years ago in reply to Mitesh Hiran

Mastermind 6235 points

I have changed the I2C address for the audio codec to 0x18 to talk to AIC3111 rather than AIC3106 but still no comms

kindly post your dts file.

Can you add some logs in the probe function in the codec driver? And check whether the probe has been called?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

Sure will try that now. But is the device tree setup correctly please?

0 Mitesh Hiran over 2 years ago in reply to Mitesh Hiran

Mastermind 6235 points

Note: with the device tree file I have uploaded above there are no more warning/error but I have not changed the clock .

(got these errors in past but not any more, not sure why? )

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Can I use dev_dbg or dev_warn messages for logs in codec divers?

0 Mitesh Hiran over 2 years ago in reply to Mitesh Hiran

Mastermind 6235 points

Looks like, if I build SDK Kernel without any changes there is no sound card found by default, This tells me there is something else wrong rather than the modification I am doing to get AIC3111 codec working.

Mastermind 6235 points

When I use the balenaEtcher to flash the 'tisdk-default-image-am62xx-evm.wic.xz' prebuild image from the SDK download path, on the modified both with TLV320AIC3111 instead of the on-board TLV320AIC3106 I can at least see a sound card but got the following error, which is expected given that the slave address of the codec are different.

Can you offer following information

which i2c address you use for your codecs?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

0x18 for audio codec TLV320AIC3111 but the SK AM62 Eval comes with TLV320AIC3106 and I2C address for that is 0x1B

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

Have they connected to the same i2c bus?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

I have disconnected AIC3106 from the I2C bus and from the Am625 SoC, hence we can't see 0x1B on the i2cdetect

0 Mitesh Hiran over 2 years ago in reply to Mitesh Hiran

both drivers are on the system. (This is by SDK default, as part of the menuconfig)

Would it matter? both have different i2c slave addresses?

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

TI__Genius 12280 points

I2C must be different.

As in, cannot be connected to the same I2C Bus? both codec have different slave address.

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

TI__Genius 12280 points

I mean i2c address must be different on the same i2c bus.

Mastermind 6235 points

That is the case. would aic3111 work when the sysclk is 12.288MHz but in the device tree it is set to 12MHz?

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

TI__Genius 12280 points

Do you want to set aic3111 as master?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

Yes please, same setup as SK AM62 just want to change the audio codec to AIC3111 rather that AIC3106

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

TI__Genius 12280 points

Here is the example to set as master

sound0: sound0 {

compatible = "simple-audio-card";

simple-audio-card,name = "tlv320aic3262-hifi";

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

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

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

simple-audio-card,cpu {

sound-dai = <&i2s0>;

//dai-tdm-slot-num = <2>;

};

sound_master: simple-audio-card,codec {

sound-dai = <&tlv320aic3262>;

system-clock-frequency = <12288000>;

};

&i2c1 {

status = "okay";

tlv320aic3262: codec@18 {

compatible = "ti,aic3262";

reg = <0x18>;

#sound-dai-cells= <0>;

status = "okay";

};

I followed the device tree of AM43x and changed AM62x as follows:

tlv320aic3111: audio-codec@18 {
#sound-dai-cells = <0>;
compatible = "ti,tlv320aic3111";
reg = <0x18>;
ai3x-micbias-vg = <1>; /* 2.0V */
status = "okay";

/* Regulators */
AVDD-supply = <&vcc_3v3_sys>;
IOVDD-supply = <&vcc_3v3_sys>;
DVDD-supply = <&vcc_1v8>;
HPVDD-supply = <&vcc_3v3_sys>;
SPLVDD-supply = <&vcc_5v0>;
SPRVDD-supply = <&vcc_5v0>;
};

codec_audio: sound {
compatible = "simple-audio-card";
simple-audio-card,name = "AM62x-SKEVM";
simple-audio-card,widgets =
"Headphone", "Headphone Jack",
"Microphone", "Microphone Jack",
"Speaker", "Speaker";
simple-audio-card,routing =
"MIC1LP", "Microphone Jack",
"MIC1RP", "Microphone Jack",
"MIC1LP", "MICBIAS",
"MIC1RP", "MICBIAS",
"Headphone Jack", "HPL",

"Speaker", "SPL",
"Speaker", "SPR";
simple-audio-card,format = "dsp_b";
simple-audio-card,bitclock-master = <&sound_master>;
simple-audio-card,frame-master = <&sound_master>;
simple-audio-card,bitclock-inversion;

simple-audio-card,cpu {
sound-dai = <&mcasp1>;
system-clock-frequency = <12000000>;
};

sound_master: simple-audio-card,codec {
sound-dai = <&tlv320aic3111>;
clocks = <&tlv320_mclk>;
};
};

and now I can detect the sound card!

Kindly prepare a stereo, 48kHz wav file. during playback, any log from codec?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

Only issue was this timeout.

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

I was hoping when I play the alsa example sound it would play as stereo. Can you tell me how to do this please ?

alsa contain a postprocessing feature, you may as well leverage it.

Sample as following

TI__Genius 12280 points

Is 3111 in master or slave mode?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

It's in master mode.

I can probe the signals and can see, BCLK, WCLK and SDIN to the codec all working but not sure about Dout from the codec.

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

TI__Genius 12280 points

Pls confirm that whether the bck and wclk are generated by tthe aic311

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

Yes, the bclk and wclk are generated by the codec. and when I play any sound from SoC I see the transfer taking place over the I2S interface and DIN to the codec is changing but Dout from the codec was always 'Z'.

thanks

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

Do you think, the time out error is due to no data returned from codec to soc?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

any update please?

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

TI__Genius 12280 points

I wonder the DOUT is the digital signal or not?

Where is the log "dma-controller: chan1 teardown timeout!" from? Which file?

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

Yes, it is.

This is the digital data output signal from the Codec. And this is connected to the SoC, was there any help from the hardware team on this please?

The logs are from dmesg.

0 Shenghao Ding over 2 years ago in reply to Mitesh Hiran

TI__Genius 12280 points

OK, Let me transfer to hardware guy, before transfer, kindly offer the register dump.

0 Mitesh Hiran over 2 years ago in reply to Shenghao Ding

Mastermind 6235 points

Thanks Shenghao.

DO you think there could be anything to do with drivers?

are there some test we can do to generate beep or amixer to test if the driver is properly set?
