Below is the memory usage of two applications:
- The minimal-configuration application is configured to only include the bare minimum of functionality for the low level kernel to run. That is, the thread scheduler and system tick.
- The default-configuration application is built with the default configuration, including a lot more functionality. See the list of Default system features above for a summary.
