Help on ADSP-21489 firmware update via RS-232

Question

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

I ported the "SSL with GUI" project from EE-345 to work with the ADSP-21489, and tested it on a 21489 EZ-KIT Lite with the Power On Self Test example. Marc has also tested it successfully on his target, and looks to be working correctly. 
 I also hit the same issue as this customer using the GUI on Windows 7 x64, so copied MisterDSPs code from this thread and adapted it to work with a Binary LDR file (see MisterDSPs original post for code to work with ASCII ldr files). As with MisterDSPs post this uses the GPL rs232 library available from here . 
 Attached are two projects - the 21489 second stage loader for VisualDSP++, and the uart Upload project which was build with Eclipse CDT.
