System Modules
System modules, such as the system ability manager (SAMGR) and DFX subsystem, provide basic capabilities for upper-layer applications. During board-level system porting, you can directly select the system modules as required without any adaptation.
SAMGR
Introduction
This service-oriented framework enables you to develop services, features, and external APIs, and implement multi-service process sharing and service invocation for inter-process communication (IPC).
NOTICE: This module must be used during board-level system porting. Otherwise, other service modules cannot run properly.
For details about how to use SAMGR, see samgr_lite.
DFX
Introduction
The design for X (DFX) subsystem mainly includes design for reliability (DFR) and design for testability (DFT), providing code maintenance and testing.
For details about how to use the DFX subsystem, see DFX.
