After compilation of TMS570LS31x project into ccs and warning i am getting like below,

Description Resource Path Location Type

    Hi Anand,

    The C/C++ compiler uses an uninitialized section .sysmem for the C run-time memory pool used by malloc(). The size of this memory pool is set at link time by using the --heap_size option. The linker creates the .sysmem section only if there is a .sysmem section in an input file.

    If --help_size is not used in linker cmd file or not included in CCS like options, 0x800 will be used as default for .sysmem.
