CCS v3.3 and CCS v6 code working together

Hi.  I am currently using CCS v3.3 for the 2812 but moving to Windows 7.  Looking at the forum, it seems as if there is a problem with CCS v3.3 and windows 7 so I am thinking about moving to a later CCS, like v6.  The problem is that there is common code already compiled with CCS v3.3 which cannot be changed. 

So the question is, can I link code from CCS V3.3 to a later CCS like V6?

    You are likely to be successful.  The CCS version doesn't matter that much, but the compiler version (which is numbered independently) does.  To get a better sense of it, please see this wiki article.

    What exactly cannot change?  Is this source code that can be re-compiled?  Or is this object code that cannot be re-compiled?  Linking against old object code, while still likely to work, is nonetheless more likely to cause problems than re-compiling old source with a new compiler.

    Thanks and regards,

    Thanks for the information on the compiler, when I looked at Help->About->Component Manager->Build Tools->TMS320C28xx it showed v4.1.3

    On the not changable common code it is an "elf" file ( so yes it is object code).  I cannot recompile. 

    With this information, should I try to get CCS V3.3 to run on my windows 7 machine?

    Thanks.

    What makes you say that?  The C2000 compiler can only create COFF object files, not ELF.

    That is not officially supported, though we have heard reports of users making it work.

    Thanks and regards,

    Sorry you are right, not elf, but a .out file.
