AM625: The MIC IN of TLV320AIC3106 is unable to record

Chauncy ruan

Part Number: AM625
Other Parts Discussed in Thread: TLV320AIC3106

Tool/software:

Problem description:

I used the TLV320AIC3106 and found that when the MIC IN was recording the sound, it failed to do so. However, the line in and SPK functions of this chip are normal.

My dts configuration:

/{
......
    tlv320_mclk: clk-0 {
		#clock-cells = <0>;
		compatible = "fixed-clock";
		clock-frequency = <12288000>;
	};

Hello Chauncy,

Apologies for the delayed response here.

What version of Linux SDK are you using? Are you using a custom board or a TI EVM?

How are you running your tests?

Please provide the terminal output so that we can see exactly what steps you are taking, and any output you are seeing.
Please provide your terminal output so we can see how the peripheral is getting initialized during boot

Regards,

Nick

Hello

* Now my DTS has been modified to：

/{
......
    tlv320_mclk: clk-0 {
		#clock-cells = <0>;
		compatible = "fixed-clock";
		clock-frequency = <12288000>;
	};

	codec_audio: sound {
		compatible = "simple-audio-card";
		simple-audio-card,name = "scb7138-audio";
		simple-audio-card,widgets =
			"Headphone",	"Headphone Jack",
			"Line",		"Line In",
			"Microphone",	"Microphone Jack";
		simple-audio-card,routing =
			"Headphone Jack",	"HPLOUT",
			"Headphone Jack",	"HPROUT",
			"LINE1L",		"Line In",
			"LINE1R",		"Line In",
			"LINE2L",		"Microphone Jack",
			"LINE2R",		"Microphone Jack", //add
			"Microphone Jack",	"Mic Bias";
		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>;
		};

		sound_master: simple-audio-card,codec {
			sound-dai = <&tlv320aic3106>;
			clocks = <&tlv320_mclk>;
		};
	};
};

* I use custom-made boards；

* The SDK I use is: ti-processor-sdk-linux-am62xx-evm-09.02.01.10-Linux-x86-Install.bin；

* I tested directly using the sound recorder application;

* The following are some logs about the sound card：

Hi Chauncy,

I understand from your DTS that Codec is the Clock initiator and MCASP is receiving the clock. This is the same on our EVM.

Does playback work fine? What's different from our EVM vs. Custom board with regards to codec and MCASP interfacing?

Can you also share us if you are able to see the BCLK and WCLK/Frame sync correctly on the logic analyzer/oscilloscope? Whats the expected BCLK and WCLK?

Are you seeing the data on AXR pin of MCASP1?

Best regards,

Suren

Hi Chauncy,

Whats the BCLK, WCLK that you are expecting?

Also, can you check the padconfig register if RXACTIVE is enabled in order to record to function properly?

Best Regards,

Suren

I'm not quite clear about how BCLK and WCLK are normal for MIC IN.

Also, may I ask in which file can the detailed information of this register be viewed? I couldn't find a description about it in the materials here.

Thank you for your help

Hi Chauncy,

What is the value of BCLK and WCLK you are expecting? Did you check the MCASP1 registers or MCASP1 Pins to see those desired clock frequencies?

The padconfig register for L23 is F4084h. Use devmem2 and this address to dump the value.

Best Regards,

Suren
