Choosing a linker configuration file
The config directory contains ready-made linker configuration files for all supported devices. The files contain the information required by ILINK. The only change, if any, you will normally have to make to the supplied configuration file is to customize the start and end addresses of each region so they fit the target system memory map. If, for example, your application uses additional external RAM, you must also add details about the external RAM memory area.
To edit a linker configuration file, use the editor in the IDE, or any other suitable editor.
Do not change the original template file. We recommend that you make a copy in the working directory, and modify the copy instead.
Each project in the IDE should have a reference to one, and only one, linker configuration file. This file can be edited, but for the majority of all projects it is sufficient to configure the vital parameters in Project>Options>Linker>Config.
