Hi Sal,

I have created a Linux driver for TAS5805M. It can be reused for TAS5825M and few modifications are expected since TAS5805M and TAS5825M share very similar register maps on Book 0.

See the zip file and some slides below. Note that customers need to generate the header files in the TAS5825M plug-in.

Hi Andy,

Thank you for the info. I got TAS5825M working now.

Just one more question.

I have 4 TAS5825M I need 2 of them to be configured with a particular values during driver initialisation and the other two with different values.
How can I do the this in the driver ?

Regards

Hi Cijoy,

The easiest way I can think of now is to create a driver separately for each of these 4 TAS5825M devices since these 4 devices have 4 different i2c addresses. In this way, each driver / device can use different configurations.
