Compiler/TMS320F28377D: redefining CLAscratch section?

Tool/software: TI C/C++ Compiler

Dear readers,

I'm having 1 software project for two CPU cores so I only need to flash 1 CPU core with 1 firmware file for the entire controller.

I've divided the FLASH in pages for specific code sections which are copied through the IPC to the right RAM area (CPU1, CLA1, CPU2 and CLA2).

That all works just fine, i'm only running into some difficulties with the CLAmath library and things could be done more easy if I could redefine some sections for CLA2

like for the 2nd CLA renaming the CLAscratch -> CLA_2scratch

Is this possible?

Or maybe it's possible to put all the sections of CLA sources in folder to a specific page ( CLA_RAM: { projectfolder/dir/*.obj(CLAscratch) }

Or some other advanced techniques

Tjarco,

I've asked the compiler team to comment on this question. The scratchpad naming convention information is commented in section 10.2.4 of the compiler user's guide (http://www.ti.com/lit/spru514).

Tjarco,

Could you please send more details on how you are trying to use each cla1 and cla2?

And perhaps the linker map files and your linker cmd files?

What version of compiler and clamath lib are you using?

Thanks,
Greg

Hi Tjarco,

I'm looking at this again and would like to understand why you would like all of the code for both subsystems in one project. Having one project per subsystem is very straight forward and is how we recommend building up the application. Understanding your use case will help.
