CCS TI ARM Linker Allocating Too Much SRAM

Other Parts Discussed in Thread: TM4C123GH6PM

I'm building a CSS project for a TM4C123GH6PM microcontroller using FreeRTOS and am currently trying to figure out why the linker is allocating nearly 30kB for the .bss heap when I've explicitly specified a flag that sets the heap size to 0. Has anyone encountered this issue or found a way for explicitly setting the size of this section of SRAM?

I have attached my linker map file to this post. I appreciate any help that can be provided!

    It does so on behalf of the source code - in this case, your FreeRTOS code. Check your "FreeRTOSConfig.h" file somewhere in your project, which usually enables/disables the features included in your build. To make founded changes, you probably need to consult the FreeRTOS documentation, and your requirements.

    And to view the results, generate a map file and check the sizes of your sections.
