- // 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

- //
- // The header linker files are found in <base>DSP281x_Headerscmd
