Troubles with memory flash programing

Other Parts Discussed in Thread: TMS320F28335

I ve attempting to program a TMS320F28335 experimenter Kit on Its flash memory , I've adjusted the Linker comand file .cmd as to load to the flash and run it from the RAM but it happens that when running from the compiler the led blinks but when I reset the CPU the led turns off, so the flash never gets programed.

Can some one explain the requiered steps to program the flash memory. I've guided on C200 delfino WorkShop> lab>10 without well results. I am using CSS v4.

Hello!

Try go through that link http://processors.wiki.ti.com/index.php/C28x_Compiler_-_Understanding_Linking and that AR 8865.TI_Running_from_Flash_spra958l.pdf.

In general you need to do the following:

- define "FLASH" in "Predefined symbols" of project's properties;

- add to project the Flash version of CMD file (F28335.CMD) instead the RAM version (and don't forget about DSP2833x_headers_nonBIOS.cmd or DSP2833x_headers_BIOS.cmd depending on using DSP/BIOS in your project );

- add to project DSP2833x_CodeStartBranch.asm file.

Regards,

Igor
