Pinpack utility,

So the binpack utility appears to take in a binary input file and produce a binary output file. The command to invoke it looks like this:
binpack -i program.bin -o program_out.bin -a 0x1800

You can add this as a post-build step in CCS where you pass in the .bin file as input. If you already have a tiobj2bin command in the post-build step to generate the .bin file, then you can simply add the binpack command as a second command.

In CCSv6, it is easy to add multiple commands for the Post-build steps (just add each on a new line), as mentioned in the link I sent earlier:
http://processors.wiki.ti.com/index.php/Projects_and_Build_Handbook_for_CCS#Pre_and_Post_Build_Steps

So the first line could be the tiobj2bin command and the next line could be the binpack command.

If I am still not understanding your question, please elaborate in detail as much as possible, preferably with an example of what you would like to achieve.
