BSP and Device Driver Development Guide
The RTEMS configuration table contains the maximum number of objects RTEMS can handle during the application (e.g. maximum number of tasks, semaphores, etc.). It's used to allocate the size for the RTEMS inner data structures.
The RTEMS configuration table is application dependent, which means that
one has to provide one per application. It is usually defined
by defining macros and including the header file <confdefs.h>.
In simple applications such as the tests provided with RTEMS, it is
commonly found in the main module of the application. For more complex
applications, it may be in a file by itself.
The header file <confdefs.h> defines a constant table named
Configuration. It is common practice for the BSP to copy
this table into a modifiable copy named BSP_Configuration.
This copy of the table is modified to define the base address of the
RTEMS Executive Workspace as well as to reflect any BSP and
device driver requirements not automatically handled by the application.
For more information on the RTEMS Configuration Table, refer to the RTEMS Application C User's Guide.
