Introduction

This is a package of Perl scripts used to process the XML files that come from the TI code generation tools. Use it to do things like build a spreadsheet that details the size of all the sections, or figure out how much of the memory map is taken up by specific libraries.

These scripts are now post-processed as part of the release to create executables on Windows & Linux - so you don't need to have Perl installed as a prerequisite.

Also note that these scripts now work with COFF or ELF object file formats. They can also work with other vendor Codegen outputs - for example the scripts were tested against ELF libraries built by the MontaVista GCC ARM compiler. This is true for utilities like sectti which only depend on the (COFF or ELF) Object File information - however scripts like call_graph require detailed Dwarf debug information to obtain the call tree and stack size hence will only work with TI based CGT ELF output.

Download

cg_xml is available here
- CG_XML v1.20 or later is recommended because it contains the executable versions of the scripts. Also the RTSC Package Wizards and the QualiTI tool depend on >= cg_xml v1.20

Sample Outputs

Categorizing memory usage: -

C:\dir>ofd6x -x app.out | sectti
Reading from stdin ...
