As of the February 2007 Update for VisualDSP++ 4.5, the Expert Linker will not allow the modification of any System Builder generated LDF. These are LDFs which have been created either in the Project Wizard during creation of a project, or in the 'Project Options' dialog if modifying an existing project, using the "Add Startup Code/LDF" option. When such files are opened by the Expert Linker, they are detected as having been created by the wizard, and are opened as read only.

Changes to such LDF files should instead be made in one of the following ways:

1) Modify the settings within the appropriate sections in 'Project Options'->'LDF Settings'. Any settings not available must be modified using method 2).

2) Modify the LDF file by opening it as a text file within the IDDE (or other editor) and changing ONLY text within the $VDSG tags. These modifiable sections are denoted by:

/*$VDSG<insert-user-ldf-commands> */
/* Text inserted between these $VDSG comments will be preserved */
/*$VDSG<insert-user-ldf-commands> */

Any changes to the file made outwith these sections will be lost when it is regenerated.

System Builder Generated LDFs can be identified by comment "/*MANAGED-BY-SYSTEM-BUILDER*/" at the top of the file.
