CW 7.0 SE Unlimited Assembler/Debugger?

[swright]

Hi,

The feature matrix document for Codewarrior for Coldfire V7.0: http://www.freescale.com/files/soft_dev_tools/doc/fact_sheet/950-00395.pdf indicates that the assembler and debugger have no code size limitations only C coding is limited to 128K.  The documenation that comes with the SE download indicates a code size limitation of 128K (without distinction between assembly and C code).  Which is correct?  Is it possible to use the IDE for assembly only projects >128K?  Is the assembler/linker available via the command line?

The reason I ask is, I hope to port my current, assembly only, code base over to the Codewarrior and if satisfied, have the company I work for purchase the appropriate version for future mixed C/Assembly coding.  I would be doing the porting/testing on my own time (and dime!) so I really don't want to spend thousands of dollars up front and would instead probably use an open source alternative.

Thanks

I've only got Cw for ColdFire 6.4, but perhaps there's enough similarities to help you out. First, look in the E68K_Tools directory (it's within the CodeWarrior directory) and see if there's a sub-directory, Command_line_tools, present. It holds the command line version of the c compiler, assembler, and linker. To figure out how to use these tools, look in the (CodeWarrior Examples) directory and see if there's a CmdlineTools sub-directory. That should have some batch files that allow you to build projects using the command line.

I assume that the Weclome_to_CodeWarrior_for_ColdFire.txt file is stating: "Code size is liited to 131072 bytes" and nothing else, unlike the PDF file?

Tom, thanks for the info on the command line tools, I'll have a look at the version 7.0 directories to see if they're similar.

Yes the Weclome_to_CodeWarrior_for_ColdFire.txt file states: "Code size is limited to 131072 bytes", unlike the PDF file but also in the CodeWarrior help files under limitations for Special Edition.  What I need to know is, which document is correct?  Does the 128Kbyte limit apply to the Assembler, Linker and Debugger?

Now that I know that we're on the same page, let me look into this.

According to our engineer, the data sheet is wrong. The maximum amount of code the Special Edition linker can handle is 128 KB, whether it's from C, assembly, or a mix of the two. Put another way: assembly code size is limited to 128 KB. I hope tis clears things up.

Thanks Tom for clearing that up.  I was pretty sure that this was the case, it would be difficult to create a linker to recognize the difference between the object files created by 'C' and Assembler and yet be secure from a simple file parsing to bypass the 128K limit.  Actually I guess there is always the possibility of someone with lots of time on their hands writing their own linker., (no system is totally secure, you just want to make it too much trouble to bother with).

I guess someone should clean up the 'fact sheet' documentation.

Thanks again,

Scott
