AM625SIP: How to config the macsp0?

Roy, your question just got re-assigned to the appropriate subject matter expert. We'll get back here shortly.

Roy,

The Device tree changes look okay. Also can you share the main_mcasp0_pins_default { } for the pincontrols to see if everything is correct.

You can refer our DTS file: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-am62x-sk-common.dtsi?h=ti-linux-6.6.y#n574 where we are using MCASP1 and codec is the initiator of the clocks.

Best Regards,

Suren

Hi Suren，

When I use the device tree， the card cannot be registered, log:
[ 9.268032] davinci-mcasp 2b00000.audio-controller: ASoC: error at snd_soc_dai_set_fmt on 2b00000.audio-controller: -
22
[ 9.284788] asoc-simple-card: probe of sound failed with error -22

I add "format = "i2s" "  in dailink:

sound_master: pdm-to-i2s {
#sound-dai-cells = <0>;
compatible = "adi,adau7002";
};

codec_audio: sound {
compatible = "simple-audio-card";
simple-audio-card,name = "AM62x-SKEVM25";
simple-audio-card,format = "dsp_b";
simple-audio-card,bitclock-master = <&sound_master>;
simple-audio-card,frame-master = <&sound_master>;

simple-audio-card,dai-link@0 {

format = "i2s"
cpu {
sound-dai = <&mcasp0>;
};
codec {
sound-dai = <&sound_master>;
};
};

};

The sound card can be registered, but when I use: 

root@am62xx-evm:/proc/asound/AM62xSKEVM25/pcm0c# arecord -fS32_LE  -c 8 -D hw:0,0 /tmp/test.wav

the log:

Hi Roy,

you have configured as I2S and tdm-slots=2 can you please run the arecord command with -c 2 option and see if it works

	};
};

but I used the commend:
arecord -Dhw:0,0 -fS32_LE -c 8 -r 48000 -t wav /tmp/test.wav, the log show:
arecord:pcm_read:2221  read:error:Input/output error

-c 2 is the same error.

The use 4 adc, each adc provide 2ch data, total provide 8ch data, the bck is 3.07Mhz, the fclk is 48000, provide by external clk_gen.

By the way, do we support 4ADC/2CH merget to 8ch tmd format? 

Hi Roy,

Please explain more clearly, I didn't understand your previous query.

Also, are you able to probe MCLK, BCLK and FSYNC on MCASP0 pins?

Best Regards,

Suren

Hi Suren,

Our customer wants to get 8ch recording. They are using the four data lines of mcasp0 to connect to 4 ADC, with each ADC providing 2 ch of data. The ADC,BCLK,LRCK are all generated by an same external clock. The BCLK is 3.07Mhz,FCLK is 48Khz. I have configured the device tree, but it seems that I cannot record correctly, and it prompts the pcm read error 2272 mentioned earlier.

Our customer's chip does not have MCLK connected. Are you suggestion to use an oscilloscope to check the waveform on the pin corresponding to BCLK and FSYNC?

Yes Roy. 

Please connect a logic analyzer to check the BCLK and FSYNC.

Also if you want to record 8 channel recording, you would have to use 4 serializers in RX, which is what I see you are doing in Device tree.

Also have you tried to change the mic bias and see if it helps you record?

Hi Suren,

When customer uses the command shown in the figure, the waveform displayed on the logic analyzer  is shown in the first 4 figures.

The waveform from top to bottom are BCLK, FSYNC and data 1-4.

If there is a problem with the mic, the arecord command should not fail, it would just record distorted or poor-quality wav file.

Hi Roy,

What  Linux SDK version is the customer using?

Best Regards,

Suren

Hi Suren,

The Linux SDK version is ti-processor-sdk-linux-am62xxsip-evm-09.02.01.10.

Hi Roy,

As discussed today, please share the register dump with 2 channel recording (working) and 8 channel recording (non-working scenario) for us to analyze.

Best Regards,

Suren

Hi Suren,

The files in the attachment are the raw data(include registers, record command and sound wav files1050.test_data.zip) from the customer test, so to make it easier for you to view the registers, I have organized the registers of several different device tree configuration modes, the abnormal registers value is mark as red color.

Test 1:
tdm-slot=<2>
serial-dir =<
2 0 0 0
0 0 0 0
0 0 0 0
0 0 0 0

MCASP_RGNLCTL 0x1f
MCASP_RMASK 0xffffffff

MCASP_RTDM 0x3
MCASP_RINTCTL 0x1
MCASP_RSTAT 0x154
MCASP_RSLOT 0x1
MCASO_RCLKCHK 0x0

Test 2:

MCASP_RSTAT 0x154
MCASP_RSLOT 0x0
MCASO_RCLKCHK 0x0

Test 3:

Test 5:

MCASP_RSTAT 0x15e
MCASP_RSLOT 0x5
MCASO_RCLKCHK 0x0

Hi Roy,

Since their A/D converter supports 24 bit analog input, can you try and capture in S24_LE format and see if it works correctly?

Best Regards,

Suren

Roy,

The RSLOT shows 0x5, is it because you have configured tdm-slots=8 instead of 2? 

Best Regards,

Suren

Hi Roy,

Also can the customer try to capture 4 channels instead of 8 and see if it works fine? Also does capturing in 8Khz or 16Khz make any difference?

With tdm-slots=<2> in DTS.

Best Regards,

Suren

Hi Suren,

The customers had tested 4ch, same like 8ch, the wav file is L L R R, and the speed is abnormal. The customers also tested 8khz or 16khz, if 16K or 8K is used and recording cannot be done with the arecord command, an incorrect sampling rate is indicated.

Hi Suren，

Yes, it is tdm-slot=8. If customer configures device tree like:
tdm-slot=<2>
serial-dir =<
2 2 2 2
0 0 0 0
0 0 0 0
0 0 0 0
>,

the registers:

MCASP_RGNLCTL 0x1f
MCASP_RMASK 0xffffffff
MCASP_RFMT 0x180f0
MCASP_RTDM 0xff
MCASP_RINTCTL 0x1
MCASP_RSTAT 0x15c
MCASP_RSLOT 0x0
MCASO_RCLKCHK 0x0
