No SoundCard (tlv320aic3x) is detected

Other Parts Discussed in Thread: DA8XX

Hi,

I am working with a custom board with DM365. The codec IC is connected in I2S mode to the DM365.

I have given the dai_link parameters as below.

static struct snd_soc_dai_link custom_dai = {
        .name = "TLV320AIC3X",
        .stream_name = "AIC3X",
        .cpu_dai = &davinci_i2s_dai,
        .codec_dai = &aic3x_dai,
        .init = custom_aic3x_init,
        .ops = &custom_ops,
};

But for me the davinci_i2s_probe function is not called and cpu dai is not registering and sound card is not detecting.

Could you please tell me why davinci_i2s_probe function is not getting invoked. I am working with 2.6.32 kernel

Thank you, Sreedhar

Hi,

You can refer to the da8xx_evm_dai struct as a reference for what to do. If you have made appropriate changes in the davinci-evm.c file and registered the platform device in board file the probe should be called.

Hi Vaibhav,

Thank you, i found the issue.

dm365_init_asp(&dm365_leopard_snd_data); is not called in my board file.
