As the CMB is built with two PCM1864 ADCs and it is also a Beagle board, I followed this guide( https://www.ti.com/lit/an/sprac97/sprac97.pdf ) with some changes(channels_max=16). I have managed to record audio from 4 of the 8 microphones that the CMB has(I just tap the mic to check if that one is working). However I want to record the 8 channels. Currently the working microphones are MIC1, MIC4, MIC5 and MIC8, although I would say there is much noise.The CMB has 4 data output pins, I suppose each one transmits 2 channels, so the problem is that each pin is getting mono instead of stereo. This might be because a problem in DTS, therefore this is my dts file: pcm5102a: pcm5102a { #sound-dai-cells = ; compatible = "ti,pcm5102a"; status = "okay"; }; sound {compatible = "simple-audio-card"; simple-audio-card,format = "i2s"; simple-audio-card,name = "PCM5102a"; simple-audio-card,bitclock-master = ; simple-audio-card,frame-master = ; simple-audio-card,bitclock-inversion; simple-audio-card,cpu { sound-dai = ; }; sound1_master: simple-audio-card,codec { #sound-dai-cells = ; sound-dai = ; //clocks = ; //clock-names = "mclk"; }; }; &mcasp1 { #sound-dai-cells = ; pinctrl-names = "default"; pinctrl-0 = ; status = "okay"; op-mode = ; /* MCASP_IIS_MODE */ tdm-slots = ; num-serializer = ; serial-dir = ; rx-num-evt = ; tx-num-evt = ; }; The serial-dir is that way because I use mcasp1_axr0, mcasp1_axr1, mcasp1_10 and mcasp1_axr11 ,those are the ones available in Beaglbone AI. I connected the pins DATA1-MiniDSP, DATA2-MiniDSP, DATA3-MiniDSP and DATA4-MiniDSP in J5(of the CMB) to these pins in my Beaglebone: P9.18b 173 fast rx 0 mcasp 0 d0 mcasp@48460000 (mcasp1_pins) P9.17b 174 fast rx 0 mcasp 0 d1 mcasp@48460000 (mcasp1_pins) P9.30 183 fast rx 0 mcasp 0 d10 mcasp@48460000 (mcasp1_pins) P9.28 184 fast rx 0 mcasp 0 d11 mcasp@48460000 (mcasp1_pins) I also conected DATA1-MiniDSP, LRCLK and BCLK to an external I2S DAC to make a test and I could hear MIC1 and MIC2. So I can assure that outputs are coming in stereo. My problem is that when connect the outputs to Beaglebone and record, I just get 1 of those 2 channels for each DOUT. I checked all of them just in case with the external I2S DAC: Data 1 is giving MIC1 and MIC2 Data 2 is giving MIC5 and MIC6 Data 3 is giving MIC3 and MIC4 Data 4 is giving MIC7 and MIC8 In case it helps, here is myDummy CODEC: #include #include #include #include static struct snd_soc_dai_driver pcm5102a_dai = { .name = "pcm5102a-hifi", .playback = { .channels_min = 2, .channels_max = 2, .rates = SNDRV_PCM_RATE_8000_192000, .formats = SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S24_LE | SNDRV_PCM_FMTBIT_S32_LE }, .capture = { .stream_name = "Capture", .channels_min = 1, .channels_max = 16, .rates = SNDRV_PCM_RATE_8000_192000, .formats = SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S24_LE | SNDRV_PCM_FMTBIT_S32_LE }, }; static struct snd_soc_codec_driver soc_codec_dev_pcm5102a; static int pcm5102a_probe(struct platform_device *pdev) { return snd_soc_register_codec(&pdev->dev, &soc_codec_dev_pcm5102a, &pcm5102a_dai, 1); } static int pcm5102a_remove(struct platform_device *pdev) { snd_soc_unregister_codec(&pdev->dev); return 0; } static const struct of_device_id pcm5102a_of_match[] = { { .compatible = "ti,pcm5102a", }, { } }; MODULE_DEVICE_TABLE(of, pcm5102a_of_match); static struct platform_driver pcm5102a_codec_driver = { .probe = pcm5102a_probe, .remove = pcm5102a_remove, .driver = { .name = "pcm5102a-codec", .of_match_table = pcm5102a_of_match, }, }; module_platform_driver(pcm5102a_codec_driver); MODULE_DESCRIPTION("ASoC PCM5102A codec driver"); MODULE_AUTHOR("Florian Meier "); MODULE_LICENSE("GPL v2"); and also my CMB configuration: uint8_t U1_PCM1864_CONFIG[][2] = { {0x00, 0x00}, // Change to Page 0 {0x01, 0x40}, // PGA CH1_L to 32dB {0x02, 0x40}, // PGA CH1_R to 32dB {0x03, 0x40}, // PGA CH2_L to 32dB {0x04, 0x40}, // PGA CH2_R to 32dB {0x05, 0x86}, // Enable SMOOTH PGA Change; Independent Link PGA; {0x06, 0x41}, // Polarity: Normal, Channel: VINL1[SE] {0x07, 0x41}, // Polarity: Normal, Channel: VINR1[SE] {0x08, 0x44}, // Polarity: Normal, Channel: VINL3[SE] {0x09, 0x44}, // Polarity: Normal, Channel: VINR3[SE] {0x0A, 0x00}, // Secondary ADC Input: No Selection {0x0B, 0x44}, // RX WLEN: 24bit; TX WLEN: 24 bit; FMT: I2S format {0x10, 0x03}, // GPIO0_FUNC - SCK Out; GPIO0_POL - Normal {0x11, 0x50}, // GPIO3_FUNC - DOUT2; GPIO3_POL - Normal {0x12, 0x04}, // GPIO0_DIR - GPIO0 - Output {0x13, 0x40}, // GPIO3_DIR � GPIO3 - Output {0x20, 0x11} // MST_MODE: Master; CLKDET_EN: Disable }; uint8_t U2_PCM1864_CONFIG[][2] = { {0x00, 0x00}, // Change to Page 0 {0x01, 0x40}, // PGA CH1_L to 32dB {0x02, 0x40}, // PGA CH1_R to 32dB {0x03, 0x40}, // PGA CH2_L to 32dB {0x04, 0x40}, // PGA CH2_R to 32dB {0x05, 0x86}, // Enable SMOOTH PGA Change; Independent Link PGA; {0x06, 0x41}, // Polarity: Normal, Channel: VINL1[SE] {0x07, 0x41}, // Polarity: Normal, Channel: VINR1[SE] {0x08, 0x44}, // Polarity: Normal, Channel: VINL3[SE] {0x09, 0x44}, // Polarity: Normal, Channel: VINR3[SE] {0x0A, 0x00}, // Secondary ADC Input: No Selection {0x0B, 0x44}, // RX WLEN: 24bit; TX WLEN: 24 bit; FMT: I2S format {0x10, 0x00}, // GPIO0_FUNC – GPIO0; GPIO0_POL - Normal {0x11, 0x50}, // GPIO3_FUNC - DOUT2; GPIO3_POL - Normal {0x12, 0x00}, // GPIO0_DIR - GPIO0 - Input {0x13, 0x40}, // GPIO3_DIR � GPIO3 - Output {0x20, 0x01} // MST_MODE: Slave; CLKDET_EN: Enable }; So what is wrong?
