I checked the return value of submitbuffer function which is not zero, so I feel probably submitbuffer is the culprit. Here is the code any valuable suggestions would be of great help. Wishing y...

Howdy Willer, Looks like a homework problem. Learning how to debug is really something important to understand. The first question you _always_ ask of any electronic problem is: "Is it plugged in?" In this case, you are looking at power supplies, but even those have a source of power. Another way to look at that question is to ask "Are the source voltages good?" When you have mult...

Hi all, I am developing a project based on Talkthru example for ADSP-214xx (21489 AD1939 C Block-Based Talkthru 48 or 96 kHz). While debugging the project I noticed strange behavior with Codecs Input/Output. The problem occurs if you HALT a running program on DSP and than restart it without loading / reloading / rebuilding the project. While looking for the problem, I also tested the default Ta...
