29  * EFFS-STD configuration file for MOD5282 processor flash memory. This file is part
30  * of an example that allocates 64kB of flash space to the file system, and the
31  * rest to the application.
32  *
33  * To modify the amount of space allocated to the file system:
34  *
35  * 1. Change the definition in this file: #define FS_SIZE ( 64 * 1024 )
36  * 2. Change the compcode memory address range for the application in your
37  * NBEclipse project settings so that the end of the application space does
38  * not exceed the start of the file system space. See the EFFS Programmer's
39  * Guide for details, and the header comments in main.cpp of this example
40  * on how to make the changes in the NBEclipse project.
41  * 3. Be sure to add the \Nburn\lib\StdFFile.a library to your NBEclipse project
42  * C/C++ build linker library options. See the header comments in main.cpp
43  * for this example on how to add the library in the NBEclipse project.
