Hi Everyone,

Greetings for the day.

In one of our design, we are interfacing TLV320AIC3253 Audio CODEC with Eyenix EN675-M1 ISP.

The requirement is Stereo Digital MIC with Volume Control.

This ISP EN675-M1 is running on Linux Kernel 4.2.

Do you have drivers for this Kernel ?

If do, please share the same.

Regards,

Hi,

It doesn't look like we have any drivers supporting this exact device, but there are Linux kernel drivers supporting the TLV320AIC32x4 line of devices, or the TLV320AIC326x devices. You could try the tlv320aic32x4 or tlv320aic326x drivers, but you would probably have to edit the driver code itself. You can read about the supported devices with Linux drivers here: https://e2e.ti.com/support/audio-group/audio/f/audio-forum/773056/faq-linux-drivers-device-drivers-for-aic31xx-dac31xx-aic325x-aic320x-aic326x-aic321x

I would recommend, if you can, to switch to a different part with already supported Linux driver code for the easiest implementation.

Best,
Mir

Hi Mir,

Thanks for your response.

Can you suggest what are the changes which has to be implemented if TLV320AIC32x4 (or) TLV320AIC326x drivers ? So we can use for TLV320AIC3253.

Unfortunately I do not know what parts of the file would need to be changed. But, if there is a section of the code that looks for a specific "name" of the device, you would want to change it to be the 3253. I would recommend getting a different audio codec that has the drivers if you are not a Linux audio driver expert, as we do not have anyone on our team who can support a non-Linux-kernel audio device driver. Sorry about this.

Best,
Mir
