Next, let’s discuss the Linker Command file. Embedded programming often requires you to precisely specify where sections of the program and its data must reside in memory. You can accomplish this using the Linker Command file. This is a text file that contains a set of commands and information that instruct the linker on the addresses to assign to every code and data section that make up the program.

This Linker Command file typically has an extension of .lcf, although there are exceptions to this rule. The DSP tools accept a .cmd extension. The file is read by the linker whenever the build uses a Linker Command file, whether required or optional.
