Hi ,

I want to do with McAsp0 audio collection by sii9233a.
++Error:

++The value of the register:

    Hi user4252232,

    Do you use EZSDK 5.05.02.00?

    Do you use DM816x TI EVM or DM816x based custom board?

    Do you need to capture audio (arecord) with McASP0?

    See if the below wiki pages will be in help:
    processors.wiki.ti.com/.../TI81xx_PSP_Porting_Guide
    processors.wiki.ti.com/.../TI81XX_PSP_AUDIO_Driver_User_Guide - see Audio.zip ("Use different McASP instance").

    Regards,
    Pavel

    Hi ,
    sorry, I don't have a clearly stated. I use DVRRDK_04.00.00.03 and DM816x based custom board .
    I have according to you give these documents to operate.
    Generate the equipment:
    root@ti81xx:~# arecord -l
    **** List of CAPTURE Hardware Devices ****
    card 0: SOUND0 [TI81XX ETV SOUND0], device 0: AIF1 rt5640-aif1-0 []
    Subdevices: 1/1
    Subdevice #0: subdevice #0
    And then Run:
    arecord -D plughw:0,0 -d 10 -c 2 -t wav -r 44100 -f "Signed 16 bit Little Endian" /mnt/ti8168/test.wav
    An error：

    Hi Mr cai,

    In DM816x TI EVM we have McASP2 connected to TLV320AIC3106 audio stereo codec, controlled through i2C0. While on your custom board you have McASP0 connected to RT5640 audio codec, controlled through I2C0?

    arecord -D plughw:0,0 -d 10 -c 2

    static u8 ti8168_iis_serializer_direction_0[] = {
    TX_MODE, RX_MODE, INACTIVE_MODE, INACTIVE_MODE,
    INACTIVE_MODE, INACTIVE_MODE, INACTIVE_MODE, INACTIVE_MODE,
    INACTIVE_MODE, INACTIVE_MODE, INACTIVE_MODE, INACTIVE_MODE,
    INACTIVE_MODE, INACTIVE_MODE, INACTIVE_MODE, INACTIVE_MODE,
    };

    I see you are trying to use 2 channels, one for transmit/playback and one for receive/capture. Have you check the RT5640 datasheet? Does RT5640 support this configuration (like AIC3106)? You have to compare AIC3106 and RT5640 to see if you can use RT5640 in the same way.

    Also RT5640 driver do not exist in DM816x DVRRDK 2.6.37 linux kernel, we have AIC3106 there, but not RT5640:

    linux-dvr-rdk-dm81xx/sound/soc/codecs/tlv320aic3x.c

    The RT5640 driver comes from v3.11 onwards. You can take it from AM335x SDK7:

    ti-sdk-am335x-evm-07.00.00.00/board-support/linux-3.12.10-ti2013.12.01/sound/soc/codecs/rt5640.c

    Did you integrate the RT5640 driver in the 2.6.37 dvr kernel?

    Mr cai said:
    .txnumevt = 1,
    .rxnumevt = 1,

    You might set there 32 or 64, see the below patch:

    Mr cai said:
    // .clk_input_pin = MCASP_AHCLKX_OUT,

    In DM816x TI EVM, the AIC3106 codec MCLK is clocked via a 24.576MHz oscillator. What about your custom board?

    Mr cai said:
    ti81xx_register_mcasp(0, &ti8168_evm_snd_data_0);

    In DVRRDK code base we have:

    linux-dvr-rdk-dm81xx/arch/arm/mach-omap2/board-ti8168dvr.c:    ti81xx_register_mcasp();

    linux-dvr-rdk-dm81xx/arch/arm/mach-omap2/board-ti8168evm.c:    ti81xx_register_mcasp();

    In both board files, ti81xx_register_mcasp() has not parameters.

    Mr cai said:
    {
    .name = "RT5640",
    .stream_name = "AIF1",
    .cpu_dai_name= "davinci-mcasp.0",
    .codec_dai_name = "rt5640-aif1",
    .codec_name = "rt5640.1-001c",
    .platform_name = "davinci-pcm-audio",
    .init = ti81xx_evm_aic3x_init,
    .ops = &ti81xx_evm_ops,
    },

    If your board is based on DVR board, you should use the below file:

    linux-dvr-rdk-dm81xx/sound/soc/davinci/ti81xx-uddvr.c

    If your board is based on EVM board, you should use the below file:

    linux-dvr-rdk-dm81xx/sound/soc/davinci/ti81xx-evm.c

    Mr cai said:
    .codec_name = "rt5640.1-001c",

    The codec_name is made up of the name used in the codec driver along with the I2C bus and I2C address (1-0018 for the EVM). So you have your RT5640 codec on I2C bus 1 (I2C0) on addr 0x1C?

    Have you made the pinmux for McASP0?
