SCIOPTA - Real-Time Kernel

15 Building SCIOPTA Systems

15.7.2.3 Specific Module Values

For each module four values are calculated in the linker script:

<module_name>_start Start address of module RAM

<module_name>_initsize Size of initialized RAM

<module_name>_size Complete size of the module

<module_name>_mod A structure which contains the above

three addresses.

The SCIOPTA configuration utility SC

ONF is using these definitions to pass the module addresses to the kernel.

Example in the linker script:

.module_init :

{

system_mod = .;

LONG(system_start);

LONG(system_size);

LONG(system_initsize);

dev_mod = .;

LONG(dev_start);

LONG(dev_size);

LONG(dev_initsize);

ips_mod = .;

LONG(ips_start);

LONG(ips_size);

LONG(ips_initsize);

user_mod = .;

LONG(user_start);

LONG(user_size);

LONG(user_initsize);
