  • Hi Jack,

    Please provide as much of the following information to help me understand your problem:

    Basic Information:

    • What target platform are you using?
    • What is your application? 
    • What ECU version are you using?
    • Has anything else changed in your code?

    Specific Information:

    • What do you mean by "it can't remove echo"?  Is the signal at send-out the same as the signal applied to send-in?  Is some echo leaking through?
    • Are you using the same signals as before?
    • What are the signals?  Voice?  Tones?  Noise?
    • Did you implement the ecuGetPerformance() API?  If so, please provide the output from this so I can determine what state the ECU is in.
    • Can you disable the ECU and ensure that the RX and TX path signals are intact?

    This should get us started.

    Regards,
    Charlie
