Assembly Source Listings and

Program Examples

The flash array is erased and programmed by code running on the DSP core. This code can originate from off-chip memory or can be loaded into on-chip RAM. The available flash programming tools for the 'F20x/F24x allow you to program the on-chip flash module without having knowledge or visibility of the algorithms. One scheme uses the scan emulation feature of the 'F20x/F24x to load the algorithms onto the DSP and control execution, and another scheme relies on boot loader code preprogrammed into the flash memory at the facto- ry. You can find more information about these stand-alone flash programming tools on the Texas Instruments web page at http://www.ti.com. This appendix explains how to use the algorithm source files to program the flash module. You need this information to create new flash programming tools or to add such features as remote reprogrammability to a design.
