using Predefined symbols in .cfg file

tarun goel

Is there a way to access the predefined symbols in .cfg file. what I want to do is define a symbol SYM_0 and then in .cfg file

if(SYM_0)

{..........}

else

{...........}

if not predefined symbols, is there any other way to access outside symbols like from a file.

Regards

Tarun,
I am assuming you are talking about predefined C symbols. CFG scripts cannot read C command lines or preprocessor macros. However, you can turn the order around and define a symbol in the CFG script and make that symbol available to C sources.
You can add the following to your CFG script:
Program.global.SYM_0 = 1;
and then in your C file you have to include <xdc/cfg/global.h>, which will make SYM_0 visible. Here is more about Program.global: http://rtsc.eclipse.org/cdoc-tip/xdc/cfg/Program.html#global

Another option is to define SYM_0 on the CFG command line, using -D option, -DSYM_0=1. Then, in the CFG script you can access SYM_0 as environment["SYM_0"]. Where exactly you need to add the -D option depends on your build setup (CCS or command line, are you using configuro).

Hi Sasha, sorry for the late reply

Yes I am using configuro, what do i need to do in order to define the symbol using -D option.

Go to Project->Properties->CCS Build->XDCtools->Advanced Options. There is a text box Java properties there, where you can click on the plus icon and add -D options. While you are there, check Show details during build so you can see the whole command line, and verify that your -D option is correctly generated.
