I am working on ADAu1761 eval board along with BF548 EZ KIT LITE. Kernel is Linux Laeeq-blackfin 3.0.8-ADI-2011R1 and toolchain also of 2011R1. After following steps from http://wiki.analog.com/resources/tools-software/linux-drivers/sound/adau1361   to generate the sigma dsp firmware,

  1. Export the config files(parameter.bin and program.bin) from SigmaStudio, right click the capture window in SigmaStudio choose 'Save as Raw Data'→'Address + Data'.

  2. Use tool sigma-firmware-util to get firmware blob:

    1. Run 'make' under the directory to get 'gen_firmware' which is an executable program used to generate firmware.

    2. Copy (parameter.bin and program.bin) into the directory and run './gen_firmware',then get 'SigmaDSP_fw.bin'

  3. Change the firmware's name to “adau1761.bin” and copy it to the '/lib/firmware/' under rootfs of the image. 

 

Did the above steps, generated the bin. Is the BIN correct ? I am getting issues with sound and hence this question. Once sure the generated bin is correct and being loaded, further steps will be evolved.
