Audio-McASP NO I2S clocks to the Codec : NO Sound : Even Sound card is detected

VISWANATH KONDAPALLI
Expert 2095 points
Other Parts Discussed in Thread: TLV320DAC3100, TLV320AIC3106, TLV320AIC3101

Hi ,

we are using AM335x and SDK-8 : for Audio codec(TLV320DAC3100) in Custom Board but the reference Sitara EVM-Starter Kit.

our Audio IOs(no change in pin-muxing) are same for the starter kit to our custom board -- 

only changes we have done is PIN-MUX:

tlv320aic3106:  here codec is clock master so , the clocks are sourced from codec to McASP 

mcasp1_pins_sleep: mcasp1_pins_sleep {
pinctrl-single,pins = <
0x10c (PIN_INPUT_PULLDOWN | MUX_MODE7)
0x110 (PIN_INPUT_PULLDOWN | MUX_MODE7)
0x108 (PIN_INPUT_PULLDOWN | MUX_MODE7)
0x144 (PIN_INPUT_PULLDOWN | MUX_MODE7)
>;
};

to : tlv320dac3100 : here codec is slave and McASP is master so changed --  this has DAC no Line-in so  DAC will be slave for I2S

mcasp1_pins_sleep: mcasp1_pins_sleep {
pinctrl-single,pins = <
0x10c (PIN_OUTPUT_PULLUP | MUX_MODE7)
0x110 (PIN_OUTPUT_PULLUP | MUX_MODE7)
0x108 (PIN_OUTPUT_PULLUP | MUX_MODE7)
0x144 (PIN_INPUT_PULLDOWN | MUX_MODE7)
>;
};

So changed to output_pull up -- but we are getting a logic High signal on BCLK and WCLK IO's and no data on the DIN IO.

we are using aplay command to play the ".wav" file we are geting an Logic high signal from the AM335x to cdoec 

we are suspecting the I2S bus.

one more changes we have done is :

static struct snd_soc_dai_link da830_evm_dai = {
.name = "TLV320AIC3X",
.stream_name = "AIC3X",
.cpu_dai_name = "davinci-mcasp.1",
.codec_dai_name = "tlv320aic3x-hifi",
.codec_name = "tlv320aic3x-codec.1-0018",
.platform_name = "davinci-mcasp.1",
.init = evm_aic3x_init,
.ops = &evm_ops,
.dai_fmt = SND_SOC_DAIFMT_DSP_B | SND_SOC_DAIFMT_CBM_CFM |
SND_SOC_DAIFMT_IB_NF,
};

to :

.dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBM_CFS |
SND_SOC_DAIFMT_NB_NF,

given in some of TI  fourm thread so we tried in that way-

e2e.ti.com/.../390265

we tried to get some solution for No Sound. 

Please correct us if we are doing wrong way

Assumption 1.   McASP is master and Codec is slave -- so we changed the pinmuxing.

Assumption 2: dai_fmt is the right we changed from DSP_B to I2S and CDM_CFM to CBM_CFM and IB_NF to NB_NF.

3#:

MCLK we are getting an triangle wave form: 2.3v amplitude and looking some offset in voltage level , is that clock is OK..??? (attached the waveform)

    You are changing the Sleep mode for the pins. You must change active mode.

    by Mistake i copied sleep -- we are doing in the Active -- "default" place only.

    We changed ".dai_fmnt " in davinci_evm.c from DSP_B to I2S and CBM_CFM and NB_NF -- so that we got some data out.

    there is some good news in the Audio -- earlier we were not getting I2S - clocks -- and the necessary events also generating too.

    This is the situation and the log :
    1 point is as we changed the codec clock rate in the dts 24MHZ to 12MHZ -- the division is to 8 from 16 -> i dont understand -- why changed.

    here we are in the edge -- not able to move to any direction to audio from the headphones .

    Please help me here --

    We fixed this issue. As we are using tlv320aic31xx.c for the tlv320dac3100 audio codec.
    As in AIC3XXX series audio codecs act as a MASTER and Frame will act as slave -- this is mentioned davinci_evm.c ---".dai_fmt " we changed here to I2S and CBS_FMS and NB_NF -- plz go through those values -- we got this from one of the thread from TI posted for dac3100 only.

    so the as the codec slave and frame -- necessary changes are pinmux -- in dts file and the .dai_fmt --- in davinci-evm.c and the mode related option in codec drvier.

    there u will get the Audio clocks.

    Still we are not get any SOUND .. but this is our progress to get the clocks to the codec.

    we are changing the register values -- try for the luck.

    we are not getting proper support from TI for the TI - Audio codecs.

    i think TI- SW team having solution for all these TI-Audio codecs but they are not supporting.

    Are you following the codec porting guide: processors.wiki.ti.com/.../Sitara_Linux_Audio_DAC_Example ?

    Have you made all necessary configurations to the snd_soc_dai_link, snd_soc_ops evm_ops structures? Have you modified the Codec hw params function & configured your kernel (via menuconfig) properly?

    Best Regards,

    YES Yordan.

    snd_soc_dai_link: Yes we changed to :
    static struct snd_soc_dai_link da830_evm_dai = {
    .name = "TLV320AIC31XX",
    .stream_name = "AIC31XX",
    .cpu_dai_name = "davinci-mcasp.1",
    .codec_dai_name = "tlv320aic31xx-hifi",
    .codec_name = "tlv320aic31xx-codec.0-0018",
    .platform_name = "davinci-mcasp.1",
    .init = evm_aic3x_init,
    .ops = &evm_ops,
    // .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBM_CFM |
    // SND_SOC_DAIFMT_IB_NF,
    .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBS_CFS |
    SND_SOC_DAIFMT_NB_NF,
    };

    snd_soc_ops evm_ops we didnt changed -- we are using same ops. and we are getting BCLK,WCLK and DIN waveforms

    Yes we are following the same link to added new codec and the necessary changes and the menuconfig -- so that our codec is loaded and the ALSA List.

    till CODEC we are getting inputs we are getting clocks. BUT NO AUDIO : Register DUMP -- can you help us in this :

    i am unable to attach here -- register file -- i am posting in the new thread -- because this thread created issue is fixed for us.

    Hi VISWANATH,

    We are design custom board  AM335x.
    McASP0 interface with codec tlv320aic3106 chip. We are using linux kernel 3.14 & codec driver use sound/soc/codecs/tlv320aic31xx.c

    plz see my thread 

    my configuration in davinci-evm.c file :-

    static struct snd_soc_dai_link evm_dai_tlv320aic3x = {

    Did u check the pin mux are correct ??
    Did u check the clocks in CRO ?? not the log statements. ??

    please mention ur problem clearly. before aplay -- there a command to check the audio device list -- did u check..??
    if u r using tlv320aic3106 -- in starter kit -- audio is coming straight away.

    I am trying to play test.wav file but no sound comes above error comes when aplay . how to solve above errors. i am checked pin muxing is correct .Master clock is comes proper 24MHz waveform but BCLK and WCLK waveform is shifted. my dai fmt is correct or not ?
    .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBS_CFS |
    SND_SOC_DAIFMT_NB_NF,

    & also checked the audio device list is aplay -l sound card is register AM335x-EDGE
    Any idea why sound is not coming ?
    Thanks

    1. Did u r audio codec is came in the ALSA list ??? it will in the boot log -- related to this there is a command -- check with that command

    2. dai_fmt is corrected.

    3. why u are setting amixer .. ??

    4. can i have which codec u r using .. ??

    regards,

    We have had some problems using the McASP driver in I2S mode. One bug we found is that the driver always puts the McASP into synchronous mode when I2S is requested. The patch below should fix that. But we still had problems with data corruption, and ended up switching to DSP B mode since both McASP and our codec supported it. DSP B mode worked fine.

    @Tejas : can i have u r dts file config for sound. and davinci-evm.c and mcasp.c and u r codec files --

    Rob and Tejas:
    1st thing is for tlv320aic3101 the existing will work as it is -- u need not do any changes -- u can test that driver in starter kit --

    then apply patches -- patches or any not required for aic3101 codec.
