I2S Codec on Euler bus of Pine A64+
#3
Hi, Thanks for the reply. the dtb file used in arbmian image is sun50iw1pi-pine64-plus.dtb. and the noticeable difference is as below
sound@1 {
compatible = "allwinner,sunxi-daudio0-machine";
sunxi,daudio0-controller = <0x4e>;
status = "disabled";
device_type = "snddaudio0";
};
I have changed the staus to "okay" and also changed the "CONFIG_SND_SOC_DAUDIO0_MACHINE=m" in the config file. With the
change I could see the kernel module sunxi-snddaudio0.ko in the /lib/modules/3.10.107-pine64/kernel/sound/soc/sunxi
However the module is not loaded.

Then I manually tried to load by calling "insmod" which returns the following errors.
De 3 11:18:00 localhost kernel: [ 982.711898] snddaudio0 sound.8: ASoC: CPU DAI (null) not registered
Dec 3 11:18:00 localhost kernel: [ 982.711953] snddaudio0 sound.8: snd_soc_register_card() failed: -517

Dec 3 11:18:00 localhost kernel: [ 982.711991] platform sound.8: Driver snddaudio0 requests probe deferral

As I understand certain dependency driver need to be install as well. Could you please help what else need to be enabled in configure file during kernel build?
the kernel version in the armbian build environment is 3.10.107

Any help will be highly apricated.
Regards
Ranjit
