    Product Number:  ADSP21569 
    
    		        		        		        
    Software Version: CCES
    
    		    		    	
			
    I work in a project that use adsp21569 with uart0, uart1 and freertos.
    

    when uart0 and uart1 are sending data, while uart1 is reveicing data, ADSP21569 runs into fatal error.
    

    the fatal error happens in the function "CommonDMAHandler".
    

    the Console prints that "a non-recoverable error or exception has occurred"
    

     
    

    what would  cause the problem?
    

    I have no idea...

      Hi,
       
      Could you please clarify whether your application is sending data via both UART0 and UART1, and at the same time trying to receive data via UART1? In your mail you mentioned that uart0 and uart1 are sending data, while uart1 is receiving data, ADSP21569 runs into fatal error. 
       
      We tried the attached porject which sends data from UART0 to UART1 in an RTOS environment. It works as expected.
       
      In order to simulate the issue, could you please share your test project which helps us to simulate the issue.
      

      Waiting for your reply.
      

      Best Regards,
      Santhakumari.K
