GENERAL: Source/Symbols in Emulator Software

Information in this article applies to:

• C51 All Versions

QUESTION

I can't see my source code or symbol information in my ICE(In-Circuit Emulator) software. What am I doing wrong?

ANSWER

There are a few things that need to be done to see your source code and symbol information in your emulator software.

1. Make sure that you're loading the absolute object file (created by the linker), not the hex-format file. The Intel hex file format does not allow for debug information to be included. The absolute object file, if you're using µVision, will have a filename of PROJECTNAME.(no extension.)
2. Make sure that debug switches are turned on for the linker, assembler, and compiler. Use DEBUG for the Assembler. Use DEBUG and OBJECTEXTEND for the C compiler.
3. For some emulators, source files must be located in the same directory as the absolute object file. If your configuration does not allow for this, your emulator software should provide a means of telling it where to find your source files. Remember, the OMF (absolute object) file does not contain your source code - it only contains references to filenames and line numbers. The source must be read from the actual source code file by your emulator software.
