Hi
Open the project settings and look in "C/C++ Build | Settings | ARM Linker | Input".
This will show you the "Linker Command File" with a path and the name of the *.lcf being used for the present target.
By default this will be in a directory high up in the project hierarchy. By adding new location defines the exact location can be changed if required:
eg. "${APPLICATION_LOC}"/Project_Settings/Linker_Files/MK60N512VMD100_ram.lcf
where the path variable APPLICATION_LOC is added as a path variable in the "Linked resources" register in the project properties.
Regards
Mark
