ccsv3.3 timake incremental build

Hi,

I am trying to use timake that comes with ccsv3.3 to do a command line incremental build:

timake SM.pjt Custom

and it does a full build every time.  Using the ccsv3.3 GUI the incremental build

works.  I am not using the '-a' flag.  If I check usage on timake I get the following

information which doesn't mention the ability to do an incremental build:

Usage: timake.exe pjt -lc | cfg [-a | -clean] [-nr]

The first parameter <pjt> is required and must be a valid project file (.pjt)

The second parameter must be one of the following:
-lc List configuration names
<cfg> A configuration name
If the second parameter is a configuration name there can be a third option.

The third option can be one of the following:
-a Rebuild all
-clean Remove all intermediate files
If the second parameter is a configuration name there can be a fourth option.

The fourth option can be:
-nr ignore recursive sub-projects

However, from the FAQ(http://processors.wiki.ti.com/index.php/CCStudio_FAQ) it implies

an incremental build will work with no -a flag:

The syntax for invoking the timake utility is:

>timake.exe PJT -lc | CFG [ -a | -clean ]

The first parameter is required.

• PJT - The name of a Code Composer Studio project file (.pjt).

The second parameter must be one of the following:

• lc: Lists the names of all configurations within the specified project. No build is performed.
• CFG: The name of a project configuration. Performs an incremental build of the specified configuration. Only files that have been modified since the last build are recompiled. For additional information, see Building a Program.

When a project configuration (CFG) is specified as the second parameter, one of the following options can be specified as the third parameter:

• -a: Rebuilds all files. By default, an incremental build is performed. This options forces the recompilation of all files.
• -clean: Removes all intermediate files that may remain following a build.

Ex:

>timake.exe modem.pjt Debug -a

So, which is it?  Does timake with ccsv3.3 do an incremental build, and if so, what am I doing wrong?

Thanks, Jason
