// TITLE:   Linker Command File For 28335 examples that run out of RAM
//
//          This ONLY includes all SARAM blocks on the 28335 device.
//          This does not include flash or OTP. 
//
//          Keep in mind that L0 and L1 are protected by the code
//          security module.
//
//          What this means is in most cases you will want to move to 
//          another memory map file which has more memory defined.

// For Code Composer Studio V2.2 and later

// In addition to this memory linker command file, 
// add the header linker command file directly to the project. 
// The header linker command file is required to link the

//
// The header linker files are found in <base>\DSP2833x_Headers\cmd

// locations within the memory map                                    */

/* -l DSP2833x_Headers_BIOS.cmd */

/* 2) In your project add the path to <base>\DSP2833x_headers\cmd to the
   library search path under project->build options, linker tab, 
   library search path (-i).

/* Define the memory block start/length for the F28335  
   PAGE 0 will be used to organize program sections
   PAGE 1 will be used to organize data sections

   Notes: 
         Memory blocks on F28335 are uniform (ie same
         physical memory) in both PAGE 0 and PAGE 1.  
         That is the same memory region should not be
         defined for both PAGE 0 and PAGE 1.
         Doing so will result in corruption of program 
         and/or data. 
         
         L0/L1/L2 and L3 memory blocks are mirrored - that is
         they can be accessed in high memory or low memory.
         For simplicity only one instance is used in this
         linker file. 
         
         Contiguous SARAM memory blocks can be combined 
         if required to create a larger memory block.
