I have an ezdsp28335 with CCSv4.1, XDC 3.16, and DSP/BIOS 6.20 and I'm preparing my project for standalone operation (which won't be on the ezdsp board).
The spraau8 application note implies that the method of copying the .text section during the codestart execution may not work when using the DSP/BIOS (Tim Love indicated he abandoned the attempt). My assumption is that this is because there is some BIOS boot code that runs prior to branching to _c_int00 which would be otherwise designated to run from RAM, but would not be copied over until after the codestart functions were run.
Would it be possible, however, to include the copy code in the Boot.xdc package or somewhere similar? There are several functions in there that I would assume get executed before the branch to _c_int00. I've read the other application notes (spra958h in particular) and have determined that it would be possible to simply assign each critical code section to RAM using the method indicated, but I'd rather run my entire application from RAM rather than just certain functions. Also, there are a few differences in the way DSP/BIOS 6.xx works compared to the application notes that seem to be based on version 5.xx which makes me wary to follow them directly.
Any help would be appreciated.
