Customizing Linker Directives File

------------------ INTEGRITY RTOS Green Hills C++ Compiler PowerPC embedded system

------------------

INTEGRITY RTOS contains default linker directives files for various BSPs and Simulator isimppc. Those files are used to build an INTEGRITY applications. There are three sorts of linker directives files:

• for Dynamic Downloadable applications (virtual AddressSpaces) , default linker directives file - INTEGRITY.ld;

• for Kernel RAM applications (KernelSpace in RAM), default linker directives file - default.ld;

• for Kernel ROM/Flash applications (KernelSpace in ROM/Flash), default linker directives file - flash.ld;

Linker directives files have comments which describe

• the various sections in the map and

• recommendations how to specify various sections to change behavior of the applications (increasing, decreasing sizes; placement of kernel in RAM, ROM, Flash; etc).

But to customize (create a new) linker directives file I need more information of its sections (how they affect an application behavior; what must not do with them; etc).

Is there some documentation describing the meaning and use of all these sections: for various BSPs and Simulators.
