Loading Flow
The processors and devices of the system can be downloaded through Loading
procedure from LSM software executables, data, and other elements, which are
required to perform their functions.
During the system initialization procedure, Loading the system is performed.
Loading is also involved when a specific board is mounted in the system, when a
hardware reset is carried out, or when the operator of an upper management
system restarts a specific board.
At the first system initialization, the system is loaded through LSM. As the loading
information is stored in the internal storage, no unnecessary loading is carried out
afterward. After the first system initialization, it compares software files and
versions of LSM and downloads the changed software files.
The loading information contains the software image and default configuration
information file, and so on.
The following figure shows the Loading signal flow:
