Code Composer Studio Version: 4.2.1.00004 genearate .s43 file

I have some legacy MSP430 assembly code that I am trying to compile to a .s43 file format.

How can I accomplish this in CCS4? The assembly code compiles OK, but  how do I get CCS4 to generate the .s43 file?

I would like to then use the .s43 in an Legacy IAR project.

    .s43 is the file extension used by assembly source files in the IAR tools. The extension used in the TI tools is .asm. Although the assembly instructions themselves are the same, IAR and CCS use different assembly directives and variable declarations.

    If your goal is to convert assembly source file from one tool syntax to another, this page might be helpful: http://processors.wiki.ti.com/index.php/IAR_to_CCS_ASM_Perl_Script

    However, depending on your source file, the conversion may not be 100%, there may still be some manual conversion you may need to do after using the script for conversion.

    There is also information on this topic in Appendix C of Code Composer Studio v4.2 Users Guide for MSP430.

    This is sort of a follow-on question to this topic.  I have a group of about thirty .s43 files in which I have to do some minor edits and then recompile.  It sounds like I'm better off just using IAR instead of translating them to  the CCS/.asm format.  Is this correct?  I'd also be grateful for any links to IAR background or reference materials that are out there.

    Thanks and regards -- Chris
