1) where is the "DSP28xxx_SectionCopy_nonBIOS.asm" file referenced in SPRAAU8? I have the header files and peripheral examples for the 2833x (SPRC530), didn't see it in there.
2) How does this actually get everything to work properly? How does this impact debugging? Can you still set breakpoints on code that runs in RAM?
From what I can tell, SPRAAU8 section 3.1.3 and 3.2.1 seem to indicate that the key to this approach is the LOAD and RUN directives... so that presumably the linker places all the final code into the "LOAD" area, but branch/jump/call addresses are set to point to the "RUN" area.
The note at the bottom of the page says that breakpoints should not be set until the copy_section routine has executed... how does Code Composer v4 figure out where to set breakpoints, anyway?
3) If there is a concern about copying time, is it possible to set the PLL to something other than 1x PLL?
