start the main application code because, if for example the main partition has been corrupted by a system
power-off during software upgrade.
Services available in the Recovery Application Code are a subset of those available in the Main Application
Code: for example VoIP modules, SSH and SNMP access are not available.
Note: Recovery Application Code uses the same configuration file as the Main Application Code. Configuration
parameters for modules not available on Recovery Application Code are simply ignored when the CPE
runs in recovery mode.
1.1.3.1.3 Main partition
The gateway operating system is named Main Application code and is stored in a third flashfs partition area (the
Main Partition) that provides permanent storage for the Main Application code, and for files that are normally used
only during system bootstrap.
During the system bootstrap the files stored in the main partition are copied into isfs in order to make them
available to all application processes. Processes typically use the isfs to store temporary configuration data.
The configuration is stored within the main partition.
1.1.3.2 Gateway with 8MBytes of FLASH with and without EEPROM
The main difference between models with and without the EEPROM is the location of unit-specific information
like MAC address, serial number, model name etc.
Figure 1-2 below depicts the two different partitions side-by-side. 8 MByte Flash Memory partitioned with and
without EEPROM
