Compiler/TMS320F28374S: Codes copied to two RAM locations (to run) which are not continuous

Tool/software: TI C/C++ Compiler

Hi,

Just one doubt: can the codes (copied to RAM) run in different RAM locations?

I'd like to copy several Flash codes to RAM and run. But, there's no enough continuous RAM size for code running. So I'd like to do like:

ramfuncs : LOAD = FLASHB_D,
RUN = RAMGS0|RAMGS6,
LOAD_START(_RamfuncsLoadStart),
LOAD_END(_RamfuncsLoadEnd),
RUN_START(_RamfuncsRunStart),
PAGE = 0

Is this OK? If OK, is there totally the same like continuous RAM?

Thanks a lot.

Jordan,

It is possible. You will need to replace the equal sign (=) with (>) for the RUN section. You can check out this page that describes how to extend across different memory ranges.

Ozino,

I don't understand about "You will need to replace the equal sign (=) with (>) for the RUN section".

The issue comes from the size of RAM, but not Flash. RAMGS0 is not enough to save all of the codes. RAMGS6 is needed.

This is why I'd like to do "RUN = RAMGS0|RAMGS6". Is this correct?

Jordan,

Yes you can do that but you need replace the equal sign (=) with a forward arrow (>) or it will fail to build. You can split the memory allocation across multiple ranges.
