Declaring the build type

informing the linker of whether the build is for a traditional ROM system or for a RAM system, helping the linker check that only suitable sections are placed in the different memory regions.

Defining available addressable memories

giving the linker information about the maximum size of possible addresses and defining the available physical memory, as well as dealing with memories that can be addressed in different ways.

Defining the regions of the available memories that are populated with ROM or RAM

giving the start and end address for each region.

Section groups

dealing with how to group sections into blocks and overlays depending on the section requirements.

Defining how to handle initialization of the application

giving information about which sections that are to be initialized, and how that initialization should be made.

Memory allocation

defining where—in what memory region—each set of sections should be placed.

Using symbols, expressions, and numbers

expressing addresses and sizes, etc, in the other configuration directives. The symbols can also be used in the application itself.

Structural configuration

meaning that you can include or exclude directives depending on a condition, and to split the configuration file into several different files.

Special characters in names

When specifying the name of a symbol or section that uses non-identifier characters, you can enclose the name in back quotes. Example: ‘My Name‘.
