Why ADSP-BF706 EZ-Kit Audio Test from POST always fails

Category: Software
Product Number: ADAU1761


I wonder if anyone here figured out why the Audio Test always fails in ADSP-BF706 EZ-Kit Power-On Self-Test (POST) sample project?

When running this Audio Test, it always fails.

 Please help me to understand:

  1. Why does Audio Test always fail?
  2. What are the reasons that it fails?
  3. Is it the problem of CODEC data output?
  4. Or is it the problem due to library functions in calculation algorithm?

Thank you for your help!
