ADAU1761 SigmaDSP firmware loading

Hi all,

I am using adau1761 to perform active noise cancellation on the audio signals. I designed a system in the sigmaDSP tool with NLMS system. I tested in the adau1761-eval board with audio input and output. It is working fine.

 

Now I integrated the eval board with BeagleBone Black using I2C and I2S. When I play audio, it is playing perfectly fine. Now i referred this Tutorial: 

SigmaDSP Firmware Utility for Linux [Analog Devices Wiki]

To create adau1761.bin file. Copied into /lib/firmware/ directory. Rebooted.

 

Now when I play the noisy input, I get the same as output. It is not really going through the blocks I designed in the tool.

From the log I found out it is loading the firmware.

 

What may be the problem?

Please help.
