TLV320AIC3111: Unable to load module in Linux

Have you compiled the CONFIG_SND_SOC?

Hi, yes its set as a module.

And yes the have tired the default drivers that came with the Linux and also tried with one from TI website. 

https://www.ti.com/tool/TLV320AIC31XXSW-LINUX#description

Try this:

Before loading AIC3111 driver, kindly load CONFIG_SND_SOC first.

Yes, in the config file, CONFIG_SND_SOUND comes before CONFIG_SND_SOC_TLV320AIC31XX 

Try compile both into kernel instead of module

Can those errors be related to device tree? I have no yet configured the device tree for Linux processor. 

would you be able to explain how to do this please? 

In menuconfig, all I get is option to select as module. 

I don't think so, the issue is Unknown symbol. The Unknown symbols are the interfaces offered by SND_SOUND.

Good to know. I was tracing back the code to see where am I getting the errors and you are correct they are from SND_SOUND. 

devicetree is a must.

Sure once I get no errors with installing the module I will look into device tree. 

edit the .config file directly.

CONFIG_SND_SOC=y

CONFIG_SND_SOC_TLV320AIC31XX=y

May I know what kind of platform AIC3111 will be integrated into?

Oh okay, will try this right away. Am I expecting the KO files to be part of the kernel ?

No KO for both SND_SOC moduce and AIC31XX modules in my way.

Sure, I am trying to load this on RPi CM4 using Bullseye Linux

Makes sense. Anyway to verify it compiled correctly, please ?

I have rebuild the modules, zImage and dtbs but it did not rebuild zImage  

I compile the AIC31xx on krnel 6.3. So compiling is not isu=ssue.As to how to rebuild zImage, kindly consult the platform vendor.

I understand that. But would there be any verification to can suggests to verify that these modules are now part of kernel? 

Will this conversion of modules to kernel code work? as the ALSA is also added as module ?

which module stands for ALSA?

when I look in menuconfig, the codec drivers are part of ALSA and inside codec drivers we have tlv320aic31xx

In my view, CONFIG_SND_SOC cotains the core of alsa in kernel side

I did directly update the .config file with the configs but after building the kernel looking back at the .config they are reverted to modules. 

tell me your compiling commands

in menuconfig

Device Driver -> SOund Card support -> Advanced Linux Sound Arch 

And this ALSA is module. 

steps taken:

1. edit the .config to mark CONFIG_SND_SOC and CONFIG_SND_SOC_TLV320AIC31XX to y

2. sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage dtbs modules 

and this is the repo I am working from . 

git clone --depth=1 github.com/.../linux

Right, probably to are done for the day. but here is where I got to. 

1. In menuconfig I was able to build the TLV320AIC31XX as part of the kernel and I can see the kernel is build again after the change.

2. before starring to configure device tree, wanted to know if there is any test to do to make sure the driver for TLV320AIC31XX is part of the kernel. 

But I do appreciate all the support given on this. 

Thanks 

Also, would you have device tree or as overlay example for RPi CM4 for TLV320AIC31XX ?

Thanks. I am still unable to verify if the codec driver has installed as part of the kernel. any suggestions please?
