SigmaStudio 3.4- I am using a Ad9140 in my system.  brett alreay helped me on one problem I was having. I am using the standard SigmaStudio generated header files. However, I find that I can not use any slew models ( clickless volume controls  etc.) or nothing  comes out of the AD1940.

I redid hte schematic to eliminate all the slew type contorls , but I have to comment out the slew ram write block  function in the default_download fucntion to get the AD19490 to pass audio. It of course works fine in the EVAL board either way.

 

Anyone have any ideas.
