Introduction
Files Managed by the LSQM1WCMB0
The LSQM1WCMB0 access controller module manages the following three types of files:
z
BootWare program file
z
Application files
z
Configuration files
BootWare Program File
The BootWare program file is used by the LSQM1WCMB0 access controller module to load the
application program. The whole BootWare program file consists of basic BootWare and extended
BootWare.
z
The basic BootWare implements system initialization.
z
Extended BootWare provides abundant man-machine interaction functions. It is used for interface
initialization for application program and boot system upgrade.
z
The whole BootWare refers to the combination of the two sections. After the basic BootWare is
started, you can load or upgrade the extended BootWare.
Application Files
The LSQM1WCMB0 access controller module supports the Dual Image function. By default, three
application files are defined for system boot:
z
Main application file (main file)
z
Backup application file (backup file)
z
Secure application file (secure file)
These files are stored in the built-in CF card, with an extension name of
.bin
.
Typically, the default application file is written into the built-in CF card before the access controller
module is delivered.
If you have loaded the three application files into the CF card, the system will use one of these three
files to boot in the order described below. For how to set the application file types, refer to section
“Setting Application and Configuration File Types” on page 5-20.
The default names and types of the application files and their loading sequence are as follows:
z
Main application file. The default name is
main.bin
, and the file type is M. It is the default
application file to be loaded when the system starts.
z
Backup application file. The default name is
backup.bin
, and the file type is B. Upon failure of
loading the main application file, the system tries to load the backup file.
z
Secure application file. The default name is
secure.bin
, and the file type is S. If the system fails to
load the backup application file, the secure application file is the last choice. If it again fails to load
the secure application file, the system will give a boot failure message.
