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?
