A separate project that creates a library of routines you want to load from flash.
A PC program analyzes the routines included in the overlay scheme, and modifies your IAR project to include the overlay manager.
The routines you want included in the overlay scheme are appended to the program image, offsets are calculated at run time, and the selected set of routines are loaded into RAM, and you call the routines as you would any code..
Takes care of forcing uncalled routines to be included in the symbol map, modifies the icf file with sizes of overlays, and sections. Also empties MMU pipeline before executing.
If you are interested in this, or any part of the NXP library, please contact me.
