I2S Codec on Euler bus of Pine A64+

[RAZZY]

I  am using an armbian build image on PINE A64+ board with the kernel 3.10.107.  During build i enabled below I2S driver as built-in.

CONFIG_SND_SOC_SUNXI_RW=y
CONFIG_SND_SOC_SUNXI_AUDIO_DMA=y
CONFIG_SND_SOC_SUNXI_TDM=y
CONFIG_SND_SUNXI_SOC=y
CONFIG_SND_SOC_INTERNAL_AUDIOCODEC=y
CONFIG_SND_SOC_INTERNAL_I2S=y
CONFIG_SND_SOC_AUDIO_CODEC_MACHINE=y
CONFIG_SND_SOC_DAUDIO_PLATFORM=y
CONFIG_SND_SOC_VIRCODEC=y
CONFIG_SND_SOC_DAUDIO0_MACHINE=y
# CONFIG_SND_SOC_DAUDIO1_MACHINE is not set
CONFIG_SND_SUNXI_SOC_HDMIAUDIO=y

 

The Internal Audio  and HDMI Audio are initialized successfully but failed to snddaudio0 which can be accessed from Euler bus pins.  below is the error log.

 

Dec  4 02:22:10 localhost kernel: [   10.453351] snddaudio0 sound.8: ASoC: CPU DAI (null) not registered
Dec  4 02:22:10 localhost kernel: [   10.453386] snddaudio0 sound.8: snd_soc_register_card() failed: -517

apaly - l returns the following

Before I tried to load as modules with below changes .

<*>   ASoC support for audiocodec
   <M>   ASoC support for internal-i2s 
   <M>   ASoC support for audiocodec machine 
   <M>   ASoC support for daudio platform. 
   <M>   ASoC support for vircodec  
   <M>   ASoC support for daudio0 machine 
   < >   ASoC support for daudio1 machine 
   <M>   ASoC support for hdmiaudio 

 

changed the device tree file for sound@1  (sun50iw1pi-pine64-plus.dtb)

sound@1 {
compatible = "allwinner,sunxi-daudio0-machine";
sunxi,daudio0-controller = <0x4e>;
status = "disabled";   -------> "okay"
device_type = "snddaudio0";
};

The result is same.   Please help me to enable I2S codec testing on Euler bus I2S pins using  Armbian build image.

try changing "status = "disabled";   -------> "okay"" to

 

Quote

status = "okay";

 

[RAZZY]

I tried

sound@1 {
compatible = "allwinner,sunxi-daudio0-machine";
sunxi,daudio0-controller = <0x4e>;
status = "okay"
device_type = "snddaudio0";
};

 

and also changed the status to "okay" on below entry.

   daudio@0x01c22000 {
                        compatible = "allwinner,sunxi-daudio";
                        reg = <0x0 0x1c22000 0x0 0x58>;
                        clocks = <0x2 0x42>;
                        pinctrl-names = "default", "sleep";
                        pinctrl-0 = <0x43>;
                        pinctrl-1 = <0x44>;
                        pcm_lrck_period = <0x20>;
                        pcm_lrckr_period = <0x1>;
                        slot_width_select = <0x20>;
                        pcm_lsb_first = <0x0>;
                        tx_data_mode = <0x0>;
                        rx_data_mode = <0x0>;
                        daudio_master = <0x4>;
                        audio_format = <0x1>;
                        signal_inversion = <0x1>;
                        frametype = <0x0>;
                        tdm_config = <0x1>;
                        tdm_num = <0x0>;
                        status = "okay";
                        linux,phandle = <0x4e>;
                        phandle = <0x4e>;
                        device_type = "daudio0";
                };
 

Even with this changes I2S at Euler pin is not working.  Does anyone tried testing I2S on Euler bus pin with kernel 3.10.107 ?

Was this you: I2S on Pine64 Euler bus ?
