Running an Application from Internal Flash Memory on the TMS320F28xx DSP (Rev. H)

Several special requirements exist for running an application from on-chip flash memory on the TMS320F28xxx DSP. These requirements generally do not manifest themselves during development in RAM since the Code Composer Studio™ debugger can mask problems associated with initialized sections and how they are linked to memory. This application report covers the requirements needed to properly configure application software for execution from on-chip flash memory. Requirements for both DSP/BIOS™ and non-DSP/BIOS projects are presented. Some performance considerations and techniques are also discussed. Example code projects are included that run from on-chip flash on the eZdspF2812, eZdspF2808, and eZdspF28335 development boards. Code examples that run from internal RAM are also provided for completeness. These code examples provide a starting point for code development, if desired.
