TLV320AIC34EVM-K: TLV320AIC34 audio codec with IMX8MP SoM

Part Number: TLV320AIC34EVM-K
Other Parts Discussed in Thread: TLV320AIC34

Hi,

I would like to connect my Variscite DT8M Custom Board with the TLV320AIC34 Evaluation Module by using an I2S connection.

For an unknow reason I cannot see SAI2_MCLK1 working properly, the value is always '0' on my oscilloscope, therefore when I try to play audio, aplay seems to be blocked.

HW configuration :

SAI vs Codec
SAI2_TXC <-> BCLK
SAI2_TXFS <-> WCLK
SAI2_MCLK <-> MCLK
SAI2_RXD0 <-> DIN
SAI2_TXD0 <-> DOUT

My device tree configuration :

	reg_audio_1v8: regulator-1p8v {
		compatible = "regulator-fixed";
		regulator-name = "1P8V";
		regulator-min-microvolt = <1800000>;

Any idea that could help ? I've tried many things but the SAI2_MCLK1 is still not moving.

  • Link to the Variscite dev kit documentation : www.variscite.com/.../

  • Hi,

    Are you using the USB-MODEVM in this setup, if you want to use external MCLK you need to configure SW2 as shown below.

    Here is the link to the EVM user guide for more detail.

    https://www.ti.com/lit/ug/slau855/slau855.pdf?ts=1633530475737&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FTLV320AIC34EVM-K

    Regards.

  • Hi Pjuandi,

    Thanks for your answer, I've done this already but it doesn't work.

    My BLCK value is always '1', MCLK '0', WCLK '0'

    When I try to play audio, aplay is blocked without any error logs :

    root@imx8mp-var-dart:~# aplay -D sysdefault:HTC2SoundCard /usr/share/sounds/alsa/Front_Left.wav

  • Hi,

    First thing first, have you checked your MCLK is correct from your source Sai2 and what frequency prior to connecting to the USB-MODEVM?

    Are you following the MCLK frequency as mentioned in the codec driver?

    If it's correct, where do you connect this MCLK in the EVM after you have configured SW2 above?

    Showing always '1' or '0' on the clock shows either the MCLK is not present from the source itself or some connection issue.

    If you set SW2 as above, you should connect MCLK at J14 and you can probe it either on the USB-MODEVM J17 header or on the TLV320AIC310xEVM MCLK pin.

    Once the MCLK is correct to the TLV320AIC310xEVM, then the WCLK and BCLK should be provided by the audio part since I think you are configuring them as master.

    Maybe send me the scope captures of MCLK, WCLK and BCLK once you have the MCLK running. Most of the time it's because the MCLK is not correct.

    Regards.

  • Hi Pdjuandi,

    MCLK is provided by the SoM and as you said BCLK and WCLK are provided by the codec as it's configured as master.

    I found the solution for MCLK, so my frequency is 12 MHz, my BCLK frequency is 1.5 Mhz and my WCLK frequency is 48 Khz when I try to play audio by using this command line: 

    root@imx8mp-var-dart:~# speaker-test -D sysdefault:HTC2SoundCard

    But I still cannot hear sound on my Headphone and speaker-test stays blocked :

    root@imx8mp-var-dart:~# speaker-test -D sysdefault:HTC2SoundCard

    speaker-test 1.1.9

    Playback device is sysdefault:HTC2SoundCard
    Stream parameters are 48000Hz, S16_LE, 1 channels
    Using 16 octaves of pink noise
    Rate set to 48000Hz (requested 48000Hz)
    Buffer size range from 64 to 16384
    Period size range from 32 to 8192
    Using max buffer size 16384
    Periods = 4
    was set period_size = 4096
    was set buffer_size = 16384
    0 - Front Left

    BLCK 1.5Mhz :

    WCLK 48Khz : 

    MCLK 12 Mhz : 

    Mathieu.

  • Hi Mathieu,

    That's good you have the clocks running, the clock frequencies look correct.

    So which path are you testing? What is your input and output?

    Can you send me your register settings?

    regards.

  • Hi,

    OK, looking at your register dump above, none of the audio path is enabled.

    Here is the detail and what's need to be set to send digital audio to HPL and HPR output:

  • See my feedback above. Your settings are not enabling the audio path.

  • Hi Pdjuandi,

    I tried to change manually the audio settings, when I open alsamixer they stay as they are, but when I try to use aplay or speaker-test everything is modified and looks like my previous i2cdump.

  • I tried a different command and I have this error message :

  • Hi Mathieu,

    I don't know why aplay or speaker-test change the settings of codec.

    It seems like they are not set with the correct input/output between the two.

    Regards.

    Peter

  • Hi Pdjuandi,

    This is my DIN CLK while I play audio and I have no input on it :

  • Hi Mathieu,

    I believe this DIN is data in and not a clock.

    Nonetheless, the issue still lies in getting the correct configuration on codec. Why the settings got changed?

    Regards.

    Peter

  • Hi Pdjuandi,

    Yes, sorry DATA and not CLK, all the other signals, BCLK, MCLK and WCLK are the same but DIN looks like that.

    Mathieu.

  • Hi Mathieu,

    Glad you fix the issue, so what's specifically you have to change in the aplay that overwrites the codec setting?

    Regards,

    Peter

  • Hi Pdjuandi,

    the codec has to be a slave and not a master, the NXP support pointed me at this configuration : 

    https://wiki.phytec.com/display/public/MD/L-1008e.A2+phyCORE-i.MX+8M+Plus+Alpha+Kit+Quickstart+Guide
    https://git.phytec.de/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8mp-phyboard-pollux-peb-av-010...

    I did a mix of their settings and mine, since it works perfectly well.
