In current implementation the name of firmware filename is hard-coded in driver. So for ADAU1761 it should be "adau1761.bin".
One solution would be to remove the adau1761 module. Copy the DSP firmware file to "/lib/firmware/" folder and load…
I have a questions regarding the analog input channels of the codec ADAU1761.
I am using the single-ended input configuration with a bypass capacitor because the codec has the input biased at AVDD/2.
Now, before to enter in the codec I would…
Please find the output below:

I attached 4 x ADAU1761 to a Blackfin in TDM8 mode, each ADAU1761 must transmit 2 audio channels to the Blackfin. I can configure all ADAU1761 so that they transmit audio on the correct TDM8 channel. The first ADAU1761 uses TDM channel 1&2, the second…
I am able to register the sound card by correcting codec name but it gives error while loading firmware.
Below is the error message:

Is there a reason to use this board instead of the EVAL-ADAU1761? (EVAL-ADAU1761 Evaluation Board | Analog Devices )
That board can evaluate the ADAU1761 and is intended for use with SigmaStudio software.
Just selecting the ADAU1761 driver on its own wont help very much. You still need a host side I2S core and driver that is able to receive the audio from the ADAU1761 as well as a so called machine driver that describes how both components are connected…
here is asound state for adau1761
Using the simple-card I get the same result.
I have added an entry to debugfs for the adau1761 driver. In this directory (/sys/kernel/debug/adau1761) I aded a file (register_r) in order to read the whole memory map of adau1761 the following…
