Hi Luis Fernando,

I need your help, please.

I have tryed to compile your driver tlv320aic32x4.c, tlv320aic32x4.h to create a new kernel module.

All steps, that I have execute, are here : sites.google.com/.../cross-compiling-linux-kernel-module

At the end, I have find some error, when compiling your source code.

Why this  errors?

Can you help me? I need to work with this codec: - tlv320aic3204

My idea is to create the new module to add on the board at my kernel . I use the Angstrom distribution.

I await your reply,

Best regards,

Ing. Francesco.

P.S.

Anyway, the way to work correctly with the codec driver, is correct. The Angstrom release, load automatically the audio codec:ti,audio-codec = <&tlv320aic3x>;

How to switch to my new driver?

the step are correctly?

1) create the new drive, through new module, compiling tlv320aic32x4.c, tlv320aic32x4.h without error

2) add new module to the kernel, that run on BBB board

3)change the dts file, that include tlv320aic32x4, compiling dts and crate dtbo

4)disable BB-BONELT-HDMI

5)load the DT file for Audio Cape

6)run ALSA

Are correct, is possible?
