Generate a Linker Script dialog box

You can use the Generate a Linker Script dialog box to create a linker script for the software application. To open this dialog box, select the application project in the Project Navigator or C/C++ Projects view, and right-click Generate Linker Script.

Note: You can also open it by selecting Xilinx Tools > Generate Linker Script.

The Linker Script Generator dialog box contains the following functions:

Name Function

Output Settings Control output options for linker script generation.

Project

Displays the name of the software application project.

Output Script

Specify the name of the generated linker script here. This linker script will be added to the linker option of the software application

Modify project build settings as follows

This drop-down list has two options:

Set generated script on all project build configurations: Select this option to use the linker script with all build configurations, (for example, run, debug, and profile).

Set generated script on project's active build configuration: Select this option to associate the linker script with the active configuration.
