For safeguarding other information, will relate in subsequent embodiment.
A kind of method flow diagram that Fig. 1 provides for the embodiment of the present invention, as it is shown in figure 1, the method is permissible
Comprise the following steps:
In 101, the new system image write internal memory that will obtain.
When embedded device is upgraded by needs, can be by the way of network or the mode of serial ports
Internal memory by new system image write embedded device.Such as, attendant can download new from network
System image to the internal memory of embedded device.Or attendant can by the way of telecommunication,
By new system image by network push to embedded device, embedded device write internal memory.Again or
Person, attendant can obtain new from other such as USB flash disk, portable hard drive etc. storage devices by serial ports
System image, and write the internal memory of embedded device；Etc..
In 102, before upgrading, the start-up parameter of startup normal to the last time backs up, and arranges liter
Level flag bit.
The parameter used is needed, including the load address of such as system kernel when start-up parameter is system start-up
Information, need the filesystem information of carry, etc..Lose in order to avoid upgrading in embodiments of the present invention
Lose rear system cannot normally start, can before upgrading, the start-up parameter of startup normal to the last time is entered
Row backup.
The embodiment of the present invention is provided with a new Information sign position, flag bit of i.e. upgrading, and is used for identifying liter
Level whether success, is arranged by this upgrading flag bit, it is possible to make during system reboot, know on
Subsystem upgrading is the most successful, determines whether to start from new system image.
Before upgrading, first to upgrading flag be configured, this be provided for instruction upgrading and not
Success.Above-mentioned start-up parameter and upgrading flag bit can serve as starting volume in code (Bootloader)
The environmental variable of outer interpolation.
In 103, the new system image obtained being verified, if verifying successfully, then continuing to hold
Row 104；Otherwise terminate current escalation process.
Two kinds of information would generally be comprised: one is this system image file institute in the file header of system image
The hardware information used, another is the MD5 value of system image file.

If it is, illustrate that this new system image is applicable to this embedded device.
The verification carried out in this step can also include new system image being carried out integrity checking, such as
File in new system image is carried out MD5 process, MD5 value and the new system image that will obtain
File header in the MD5 value that comprises compare, if unanimously, then pass through integrity checking；Otherwise
Do not pass through integrity checking.
This step is to improve the step that success rate for upgrading preferably is carried out, and is not that present invention institute is necessary
Step.It addition, the execution of this step can also be carried out, only after new system image write internal memory
Ensure to perform before step 104.If new system image verifies unsuccessfully, current except terminating
Outside upgrading flow process, it is also possible to report an error, the new system image of prompting maintenance personnel verifies unsuccessfully.
In 104, according to running system information, it is judged that the system partitioning at the system place being currently running is
The first system subregion, carries out data erasing and the write of new system image to second system subregion.

Shellfish is to second system subregion, it is achieved mode is the easiest.
In 107, in embedded device start-up course, it is judged that whether upgrading flag bit is set, if
It is to perform 108；Otherwise, 109 are performed.
If upgrading flag bit is in the state being set, then explanation upgrading is unsuccessful, therefore in 108,
The start-up parameter utilizing backup starts, and the first system subregion is the system partitioning being currently running, and terminates
This escalation process.Unsuccessful it is to say, upgrade it is also ensured that again open from the original system run
Dynamic, it is ensured that equipment will not become " brick ".
If upgrading flag is eliminated, then illustrate that the system image in second system subregion is written to
Merit, therefore in 109, according to current start-up parameter, starting the new of second system subregion write is
System mirror image, second system subregion is the system partitioning being currently running, and this upgrading is considered as successfully.I.e. smooth
Start the system after upgrading.
