C51: WHERE IS THE ABSOLUTE OMF OBJECT MODULE?


Information in this article applies to:

  • C51 Version 5.x
  • C51 Version 6.x
  • µVision2 Version 2.10

QUESTION

I'm using the C51 compiler and I can't find the absolute object module to load into my emulator. I've looked for .ABS and .OMF files but there are none. Where is the absolute OMF file and what is its filename?

ANSWER

The absolute object module (or absolute OMF file) is the output file created by the linker. This object module has NO relocatable entries. Instead all entries are assigned absolute or fixed memory locations. Additionally, the absolute OMF file includes source level and symbolic information necessary for debugging.

To create an Absolute OMF file, you must compile and link the files in your project. The file that is output by the linker is an Absolute OMF file.

By default, when you use the µVision or µVision2 IDE, the absolute object module is given the name of the project with NO extension. For example, if your project is MYCODE.PRJ, the absolute OMF file is named MYCODE.
