    Product Number:  ADSP-SC835 
    
    		        		        		        
    Software Version: CrossCoreUtilities-Rel1.8.0,
    
    		    		    
    
		    		    
		    			
    
			    
    The ADSPSC835W DSP processor can boot using UART0, which corresponds to the 0x3 hex-switch position. After pressing the reset button, the processor should enter the UART-BOOT stage.
    

    To download data in this mode, a special tool called ccsfp—located in the CrossCoreUtilities-Rel1.8.0 package—is used. The procedure involves three simple steps:
    

      

    • 

      Select the appropriate COM port
      

      • 

    • 

      Choose the desired LDR file
      

      • 

    • 

      Click the Start button
      

      • 

    

    However, this procedure failed due to a "No autobaud response" error. After a few second the fault red led indicate the error.  I kindly ask for help. The CCSFP software and booting in UART mode work without any issues with the EV-SC594 board.

        Any support?
        

        I am still testing two EVM boards: the first is the ADSP-SC594, while the second is the ADSP-SC835. To test the UART-BOOT mode and CCSFP software, I apply the same procedure, the same list of steps. Unfortunately, my test with ADSP-SC835 failed. The question is: Does the EVM, with SC835 on board, really support the flash program using the CCSFP?
        

        Best Regards

        Hi,
        

        We recommend you to follow chapter "3.11 ADSP21835W-EV-SOM and ADSPSC835W-EV-SOM Board Modification" in the "CrossCoreSerialFlashProgrammer_UsersGuide.pdf" which is available in the below path.
        

        C:\Analog Devices\CrossCoreUtilities-Rel1.8.0\Docs
        

        Also, please ensure to follow the steps provided in the manual at chapter 3.10.1.
        

        Regards,
        Santhakumari.V

          Thank you very much Santhakumari.V 
          

          for your response and for pointing out the modification to the circuit. It's not easy because the resistor are very small (0402 footprint), but I will give it a try. I believe these actions will solve the problem.
          

          Sincerely, Pawel.
