LX51: Cannot Locate Segments

Information in this article applies to:

• LX51

QUESTION

I am porting an 8051 project from the BL51 Linker/Locater to the LX51 Linker/Locater. But I'm getting now:

*** ERROR L108: SEGMENT IN LOCATING CONTROL CANNOT BE ALLOCATED
    SPACE:   CONST
    SEGMENT: ?CO?EXAMPLE
    LENGTH:  000005H

What is wrong in my invocation?

ANSWER

The LX51 Linker/Locater provides two generic directives to locate CLASSES and SEGMENTS.

These directives are able to process any kind of segments (CODE, DATA, IDATA, BIT, XDATA, ect.). However, it is required to provide a memory prefix in an address specification (C: for CODE, I: for DATA/IDATA, X: for XDATA, ect.).

You need to add the memory prefix to the address specifications in the µVision dialog Project - Options - LX51 Locate or to the addresses in the SEGMENTS/CLASSES directive.

MORE INFORMATION

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