- // Ver | dd mmm yyyy | Who | Description of changes
- // =====|=============|======|===============================================
- // 1.00| 11 Sep 2003 | L.H | Changes since previous version (v.58 Alpha)
- // | | | Removed .bss, .const and .sysmem
- // | | | These are for a small memory model. All examples
- // | | | use the large model.
- // | | | Added ECANA_LAM ECANA_MOTO and ECANA_MOTS memory
- // | | | blocks. Also allocated the register files
- // | | | to these memory blocks.
- // | | | Added CSM Password locations to Page 0
- // | | | in order to program new passwords
- // | | | 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

- Notes:
- Memory blocks on F2812 are uniform (ie same

- 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
