speaker-test error using sgtl5000 and imx27

Hello,

I would like to use the Freescale SGTl5000 audio codec with the Freescale imx27 processor.

Unfortunately, I get this error when I try to run « speaker-test »:

# speaker-test

speaker-test 1.0.28

Playback device is default

Stream parameters are 48000Hz, S16_LE, 1 channels

Using 16 octaves of pink noise

Rate set to 48000Hz (requested 48000Hz)

Buffer size range from 128 to 32768

Period size range from 64 to 16384

Using max buffer size 32768

Periods = 4

was set period_size = 8192

was set buffer_size = 32768

0 - Front Left

Write error: -5,Input/output error

xrun_recovery failed: -5,Input/output error

Transfer failed: Input/output error

The codec is connected to SSI2 pins and I would like to use the SSI0 internal port in asynchronous mode (4 wires). The command interface is I2C1. The codec seems to work because it generates both bit and frame clocks (the codec is the master) but no data are coming from the processor. I’m using kernel 4.1.7 but I have got the same error with versions 3.19.8, 4.0.5 and 4.0.9. I have also tried the « imx-sgtl5000 » driver and I get the same error. I can use « alsamixer » with no issue.

Here are my device tree bindings:

sound {

compatible = "simple-audio-card";

simple-audio-card,name = "sgtl5000-audio";

simple-audio-card,format = "i2s";

simple-audio-card,bitclock-master = <&dailink0_master>;

simple-audio-card,frame-master = <&dailink0_master>;

simple-audio-card,widgets =

"Microphone", "Mic Jack",

"Headphone", "Headphone Jack";

simple-audio-card,routing =

"MIC_IN", "Mic Jack",

"Mic Jack", "Mic Bias",

"Headphone Jack", "HP_OUT";

simple-audio-card,cpu {

sound-dai = <&ssi1 0>;

};

dailink0_master: simple-audio-card,codec {

sound-dai = <&sgtl5000>;

clocks = <&mclk>;

};

mclk: asvmpc {

#clock-cells = <0>;

compatible = "fixed-clock";

clock-frequency = <12288000>;

};

&ssi1 {

#sound-dai-cells = <1>;

status = "okay";

fsl,audmux-port = <MX27_AUDMUX_PPCR2_SSI_PINS_2>;

fsl,port-config = <

(IMX_AUDMUX_V1_PCR_SYN |

IMX_AUDMUX_V1_PCR_RXDSEL(MX27_AUDMUX_HPCR1_SSI0))

};

&audmux {

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_ssi2>;

status = "okay";

fsl,audmux-port = <MX27_AUDMUX_HPCR1_SSI0>;

fsl,port-config = <

(IMX_AUDMUX_V1_PCR_SYN |

IMX_AUDMUX_V1_PCR_TFCSEL(MX27_AUDMUX_PPCR2_SSI_PINS_2) |

IMX_AUDMUX_V1_PCR_TFSDIR |

IMX_AUDMUX_V1_PCR_TCLKDIR |

IMX_AUDMUX_V1_PCR_RXDSEL(MX27_AUDMUX_PPCR2_SSI_PINS_2))

};

&i2c1 {

clock-frequency = <100000>;

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_i2c1>;

status = "okay";

sgtl5000: sgtl5000@0a {

#sound-dai-cells = <0>;

compatible = "fsl,sgtl5000";

reg = <0x0a>;

clocks = <&mclk>;

micbias-resistor-k-ohms = <2>;

micbias-voltage-m-volts = <2250>;

VDDA-supply = <&reg_2p8v>;

VDDIO-supply = <&reg_2p8v>;

};

pinctrl_ssi2: ssi2grp {

fsl,pins = <

MX27_PAD_SSI2_FS__SSI2_FS 0x0

MX27_PAD_SSI2_RXDAT__SSI2_RXDAT 0x0

MX27_PAD_SSI2_TXDAT__SSI2_TXDAT 0x0

MX27_PAD_SSI2_CLK__SSI2_CLK 0x0

};

And the modules I have loaded before running « speaker test » :

# modprobe snd-soc-sgtl5000

[ 23.274351] sgtl5000 0-000a: sgtl5000 revision 0x11

# modprobe snd-soc-simple-card

# modprobe snd-soc-fsl-ssi

[ 79.752288] sgtl5000 0-000a: Using internal LDO instead of VDDD

# [ 79.853711] asoc-simple-card sound: sgtl5000 <-> 10010000.ssi mapping ok

# modprobe snd-soc-imx-audmux

Does anybody know what is the mistake?

Thank you for your help.

Best regards.

Dear Alexandre

I have the same issue like you.

Was you able to fix it ?

Kind regards

Wolfgang

Hello

IMX27 with SGTL5000 is not supported in official NXP BSPs.

Perhaps it makes sense to post this issue to meta-fsl-arm mailing list, https://lists.yoctoproject.org/listinfo/meta-freescale

Have a great day,
Yuri
