Hi Guys,

https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/535034

Regarding this post I have the following question:

Should I now use

#pragma DATA_SECTION(variable,".TI.ramfunc");

instead of

#pragma DATA_SECTION(variable,"ramfuncs"); ??

    This is typically used for functions and not variables, so I'm not sure why you are doing placing a variable in ramfuncs.  I think you meant CODE_SECTION and a function, not DATA_SECTION and a variable.

    If you are using the new BINIT feature of 15.x.y C2000 compiler that automatically copies functions from FLASH to RAM, you can do it a couple of different ways (provided you are using TABLE(BINIT) in your sections in your .cmd file).

    If you are using the GCC __attribute__((ramfunc)), the section must be called .TI.ramfunc otherwise the linker complains and gives an error.
    If you are just using pragma, the memory section can be called whatever you like.
