F2810 stack should only be put into data memory?

Robert Wolfe

Hello,

In the TMS320C28X Optimizing C/C++ Compiler User's Guide (spr514), page 158, it says that the stack should only be put into data memory, in memory Page 1, as shown in the attached picture.  I am wondering why this is, and what would be the possible effect of having it located in program memory, Page 0 instead?  This could have been the source of an issue that we had seen with our F2810 target, and would like to know.

Regards,

Robert

    I can't answer whether or not those specific sections MUST be on the pages specified.

    I do know that, in general, you can put data/program code anywhere you want, on either page.  This is because it is all the same physical ram, just dual-mapped.  HOWEVER, if you keep data on the data page and code on the program page, you benefit from being able to fetch an instruction, read a data value, and write a data value, all in a single cycle. If you mix it up, you can incur delays.
