TMS320F28335: Worst Case Stack question (cg_xml scripts call_graph errors)

ngohara1991

Part Number: TMS320F28335

Hello,

a search across the TI forumns told me the appropriate tool for getting the worst case stack of my program was cg_xml. 
If there is a better more recent tool, please let me know.

I am working with a project generated in CCS 6.1.0.0014.

When I run ofd6x.exe -xg  project.out | perl.exe call_graph.pl --stack_max

I get numerous parsing errors, as seen in the attached example file.

This, to me, implies the tools are not working well together in modern development.

Questions:
Am I doing something wrong with this process?

Is there a better way to get worst case stack, preferably out of Code Composer's build settings?

Thank you for any assistance.

    Hello,

    I am moving to the TI C/C++ Compiler - Forum. Someone there should be better equipped to support your inquiry.

    Best Regards,

    No, you're not.  There is a problem with how later versions of XML::Simple and the cg_xml package work together.  It is not diagnosed.  In the mean time, you can use the standalone executable form of the script in the \bin directory.  Replace "perl.exe call_graph.pl" with "\path\to\cg_xml\bin\call_graph".

    In CCS version 7.x or later, there is a feature for viewing stack usage.  In the Project Explorer View, select your project.  Then click the menu selection View | Stack Usage.

    Thanks and regards,
