Memory Map¶
The devices supported by the SimpleLink CC13xx/CC26xx SDK each contains several memory regions including RAM, ROM, and Flash. This section aims to show how these memory regions are utilized by the stack and user application.
After building your application, the full overview of all your objects and their location is stored in the .map file found in the build folder (e.g. Release folder). The .map file for a given project can be consulted to see exactly what objects reside in flash and ROM.
