// TITLE: Linker Command File For F2812 eZdsp examples that run out of RAM
// This linker file assumes the user is booting up in Jump to H0 mode

// Ver | dd mmm yyyy | Who | Description of changes
// =====|=============|======|===============================================
// 1.00| 11 Sep 2003 | L.H. | Changes since previous version (v.58 Alpha)
// | | | Added BEGIN section to the start of H0
// | | | Removed .bss, .const and .sysmem
// | | | These are for a small memory model. All examples
// | | | use the large model.
// | | | Added .esysmem section
// | | | Changed ramfuncs section to load and run from RAM
// | | | (previously this was type DSECT)
// | | | Moved peripheral register files to DSP28_Headers_BIOS.cmd
// | | | and DSP28_Headers_nonBIOS.cmd
// | | | Added CSM_RSVD memory section in FLASHA - this region
// | | | should be programmed with all 0x0000 when using the CSM

/* ======================================================
// 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
// peripheral structures to the proper locations within 
// the memory map.
//
// The header linker files are found in \DSP281x_Headers\cmd
// 
// For BIOS applications add: DSP281x_Headers_nonBIOS.cmd
// For nonBIOS applications add: DSP281x_Headers_nonBIOS.cmd 
========================================================= */
/* ======================================================
// For Code Composer Studio prior to V2.2
// --------------------------------------
// 1) Use one of the following -l statements to include the 
// header linker command file in the project. The header linker
// file is required to link the peripheral structures to the proper 
// locations within the memory map */
/* Uncomment this line to include file only for non-BIOS applications */
/* -l DSP281x_Headers_nonBIOS.cmd */
/* Uncomment this line to include file only for BIOS applications */
/* -l DSP281x_Headers_BIOS.cmd */
/* 2) In your project add the path to \DSP281x_headers\cmd to the
library search path under project->build options, linker tab, 
library search path (-i).
