Hello,
The linker does no define global symbol __TI_SYSMEM_SIZE (size of .sysmem section) like the document "ARM Assembly Language Tools v20.2.0.LTS" (SPNU118Y from February 2020) says.
The linker flags of my project contain the --heap_size option (--heap_size=0x800). The .sysmem is referenced in the source code and the linker creates the .sysmem section. It does not defines __TI_SYSMEM_SIZE, but it creates __SYSMEM_SIZE instead.
Maybe there is a newer version of the "ARM Assembly Language Tools", but a have not found it.
I am using ti-cgt-arm_20.2.7.LTS.
Regards,
Marcio.
