LX51: Finding the End of the Binary

Information in this article applies to:

• C51 All Versions

SYMPTOM

I need to locate the end of my binary image, to allow me to run a checksum on my program.

CAUSE

Set a given segment as the last, in the link order.

RESOLUTION

The LX51 linker has a feature that allows a given segment to be explicitly placed at the end of a binary image. To use this feature:

1. Create a .C file (for example, foo.C) with a single line, as follows;

   unsigned char code EOM;
   

2. Add foo.C to your project.

3. Under the Project - Options for Target... - LX51 Locate tab, add the following to the User Segments box:

   ?co?*, ?pr?*, ?co?foo(last)
   

4. EOM is now the last byte in the program binary image.

SEE ALSO

• Refer to SEGMENTS in the LX51 User's Guide.
