Individually upgrading a portion component is needed support, the risk that the aforementioned control information area is destroyed at this time is just exposed, because
Individually upgrading and switching is needed to need to guarantee to match each other again there are relevance for component, once the letter of the control information area
Breath is lost, and system can not select correct effectively software system according to pre-set default value.
For example: as shown in Fig. 2, Liang Ge software area is available when terminal device dispatches from the factory, it is assumed that software area A is primary
System, software area B are back-up system.After only upgrading JAVA environment at this time, then effectively software system is switched to " linux system A
+ bottom software A+JAVA environment B ", on this basis, after upgrading linux system again, then effectively software system will be switched to
" linux system B+ bottom software A+JAVA environment B ".Since component needs individually upgrading and switching, the group in Liang Ge software area
Part can be used staggeredly, and the control information area is most important at this time, and control information area process error, information are updated when upgrading
It loses, system can not select to select correct effectively software system.
