    Hi,
    
 
    We are looking for some assistance with adding the ability to update our
    
 
    ADSP-21489 firmware via RS-232. The fundamentals of what we want to do is
    
 
    discussed in Application Note EE-345, and we have played around with this a
    
 
    little bit, but never got it to work completely. We can continue to puzzle
    
 
    through this ourselves, but we'd rather find a consultant who can help add
    
 
    this ability into our existing software and we'll be happy to pay someone to
    
 
    help in this regard.
    
 
    If you have experience in this area and have some extra time on your hands,
    
 
    and want to earn some extra money in your pocket, please contact me.
    
 
    (Ideally the forum has some private messaging system, otherwise you could
    
 
    leave an email address. Let me know your thoughts...)
    
 
    Thank you,
    
 
    Marc

      Hi Marc,
      
 
      Sorry for the delay in response.
      
 
      In order to port the code written for ADSP-21469 processor present in the Application Note, you may have to make the following changes for it to work for ADSP-21489 processor:
      
 
        
  
      1. Make sure that you generate a LDF file corresponding to ADSP-21489 processor.
        2. 
  
      2. Change your project option to ADSP-21489 processor.
        3. 
  
      3. You may have to change the PLL initialization code for ADSP-21489 processor.
        4. 
  
      4. Also replace the DDR2 initialization code for ADSP-21469 processor with SDRAM initialization code for ADSP-21489 processor.
        5. 
 
      
 
      The initialization code for ADSP-21489 processor can be taken from any of the example codes present in the directory below:
      
 
      …\Program Files (x86)\Analog Devices\VisualDSP 5.0\214xx\Examples\ADSP-21489 EZ-Board
      
 
      When you try to make all the above changes and build the code, then please let me know what error messages do you encounter, so that we can look into it and assist you to resolve it.
