Other Parts Discussed in Thread: TMS320F2808

Hi,

I'm using CCS5.3 with a TMS320F2808 under windows xp.

My project contains a file named firmware_info.c with some constants for build date, build time and compiler version, obtained from preprocessor.

How can I forcethe compiler to refresh this file, since his time stamp nether change?

Thanks.

Basically you need to `touch` the file. On Linux you could use the touch command to do it. On windows what you can do is setup a batch file as a pre build step that does the equivalent of touching the file.

Here is an example batch file. It changes to the location of my file and then runs a special copy command to change the timestamp on the file.

cd C:\Users\John\workspace_v5_3\c28
copy /b C:\Users\John\workspace_v5_3\c28\main.c +,,

Dear JohnS,

your solution works fine, after some small modifications in batch file for more portability (versionning).

Thank you very much

I used following configuration in my projects settings:

and my batch file contains this lines:

@echo off
echo.

REM take srce_root argument from line command
set SRCE_ROOT=%1

REM replace slash by a backslash
set SRCE_ROOT=%SRCE_ROOT:/=\%

REM change directory tor source directory
cd %SRCE_ROOT%

REM refresh SRCE_ROOT as new current directory (more readable)
set SRCE_ROOT=%CD%

echo source root: %SRCE_ROOT%

REM display file that will be modificated
echo touch %2-file to force rebuild
echo.

REM apply touch command (actualize date/time modification stamp)
@echo on
copy /b %2 + ,,

Best regards
