    Hallo,
    
 
    I'm working on ADSP-BF506F ver 0.0 EZ-Kit and UART echo example (VisualDSP++ 5.0 Update 10). I want to test the driver robustness and trying to catch any line failures. Using command pair  {ADI_UART_CMD_SET_LINE_STATUS_EVENTS, (void *)TRUE} and transmitting chars from the PC to the board with faulty baudrate will provide unexpected neverending loop. When I enable deferred callbacks, line status isn't handled anymore. The functionality of handling line status of the driver is completely different in comparison with ADSP-BF533 - where is line status handling safe.
    
 
    Thanks a lot, Zdenek

        Hi Craig,
        
 
        I send you whole project in the attachment. If I change baudrate of the 
        
 
        PC Hyperterminal to 19200bd and send for example char 'k', framing error aren't 
        
 
        handled and program never come back from ISR. When I disable macro 
        
 
        USE_DEFERRED_CALLBACKS, frame error is indicating, but not only once, 
        
 
        but forever. The same settings works fine on BF533.
        
 
        Thanks you very much, Zdenek
