I was about to start hacking on xc3sprog after e-mailing the author and not hearing back, but I was curious if anyone else has done the same. I'm interested in adding programmatic support for the spartan-3 USER1/USER2 instructions, as well as getting it to program my coolrunner-II CPLD and Virtex-4 LX. Before I reinvent the wheel, has anyone else done this?

Eric, I started using xc3sprog some weks ago (tired to upgrade the windrvr6 each time I upgrade or recompile the kernel ;-) ) I made a very minor change in the detectchain.cpp in order to print the device position of each device found in the chain. I wrote also a script to help chosing the device to program graphically. Nothing about USER1/USER2... but when I've a little bit of time I would like hacking on xc3sprog too!
If You are interested I can send You the changes I made to detectchain.cpp and the script I wrote.
Have a nice day Sandro
That sounds great!
After a few hours of work this morning I've already got it programming my 4VLX25, and I just managed to get USER1 working.
This is really a testament to the original code; it is well-thought-out and easy to understand.
I've modified it to run under FreeBSD (pretty trivial changes) but nothing more (since I'm only using Spartan 3's :)
Perhaps you could put it up on Sourceforge or something similar?
Yes, Sourceforge would be a good place.
I have changes to recognise different adapters ( Xilinx parallel, Altera Byteblaster and the MPSSE machine of an FT2232 USB Adapter).
I've created the sf project as xc3sprog -- I think with all these additions we've expanded the program a bit from what its original purpose was, but there seems to be no harm in keeping the name.
Evidently SF will be contacting me in a day or two saying they've set up the project, at which point I'll upload the code and we can start accepting patches. Does anyone else want admin bits on the site? ...Eric
Eric, Any news from sourceforge ?
Sandro
They created it this afternoon; it should be up! I'm going to import the original code into svn right now... ...Eric
Eric, Great... I saw the version you uploaded is slightly different than the version I worked on! I'll check how my changes apply to your version and after i'll send you!
bye Sandro
Eric, The version you uploaded is the latest ?!?
I got it from :
Sandro
Wow, I swear I started with the same copy. I don't know how that happened... try again? Revision 2 should be the latest latest.
What is the Sourceforge Web Address?
Uwe, I'm sorry, the main project site is at:
I was meaning to put up something in the web space of the project but I haven't had time to yet. ...Eric
