SCIOPTA - Real-Time Kernel

15 Building SCIOPTA Systems

15.7.6 WIN32 Linker Script

The linking process and memory mapping is fully controlled and defined by the Microsoft® Visual C++ IDE.

15.7.6.1 Module Data RAM

In SCIOPTA system running in a real target CPU the module RAM memory map is defined in the linker scripts.

In the SCIOPTA SCSIM Simulator you need to declare the module RAM by a character array of the size of the

module.

For the system module the declaration looks as follows:

/* define module ram */

static char system_module[0x20000];

sc_module_addr_t system_mod = {

system_module,

sizeof(system_module),

};

In the delivered SCIOPTA examples the module data RAM declaration is usually included in the file system.c.

system.c SCIOPTA SCSIM Simulator setup.
