TMS320F28075: --unused_section_elimination option not shown

Part Number: TMS320F28075

Hello C2000 forum,

The TMS320C28x Optimizing C/C++ Compiler v22.6.0.LTS documentation mentions on page 27 that there is an option called --unused_section_elimination available under the Miscellaneous settings. However, I am unable to find this option. When I manually add it to the build flags, I receive a warning stating 'Unrecognized flags entered: --unused_section_elimination=off'. 

Regards,

Paul

    It is only valid when you build your project for the newer EABI.  This is configured when a new project is started.  Here is a screenshot.

    Or, it is possible to import a project that already has this configuration.

    Thanks and regards,

    Thank you George,

    based on the screenshot I provided, the project is currently configured for EABI. However, I am still unable to locate that option under the Miscellaneous settings (See screenshot from original post). Could I be looking in the wrong place? Additionally, when I create a new project, the option seems to be missing too. Interestingly, I noticed that the linker is using the default value and omitting unused sections, which is different from the behavior observed in COFF.

    When I posted my reply, your screenshots were not visible for some reason.  I see it now.

    No, you are doing everything correctly.  The support for --unused_section_elimination is incomplete.  I filed EXT_EP-11226 to have that addressed.  You are welcome to follow the entry with that link.  Feel free to use this option.  When you see ...

    ... just ignore it.
