Description
Technical field
The present invention relates to embedded device technology field more particularly to a kind of self-regeneration methods of embedded device.
Background technique
Existing embedded device, especially embedded Android device, the partition holding of file are broadly divided into following a few classes:
(1) bootloader subregion
Bootloader is stored in nor flash, can directly be accessed by cpu, and the starting of guidance system is responsible for.
(2) kernel subregion
The kernel (kernel) of operating system is independently stored in a subregion.But it is identical with following all subregions, all
It is stored using nand flash.
(3) system subregion
System subregion is responsible for storing all system files other than operating system nucleus, contains Android use
Family interface and preassembled system application.Android system will be deleted by erasing this subregion, need to enter
Recovery mode or bootloader mode go to be brushed again into firmware.
(4) recovery subregion
Recovery subregion is considered as another boot partition, can star equipment and enters recovery console and goes to hold
The advanced system of row restores and management operation.
(5) other data subregions
Including data subregion, cache partitions, sd card subregion etc., the damage of these subregions will lead to loss of data, but not
It will affect the starting of operating system.
Embedded Android system is bigger, is limited to cost reason, often deposits in nand flash, but nand
The safety of flash is not very reliable, will appear subregion damage once in a while and system the case where can not starting.In this case
Need to reinstall operating system, implementation mainly there are following a few classes:
(1) online upgrading
Process: upgrade package is obtained by network, saves it in local, reboots into upgrade mode, decompresses upgrade package, is used
File therein replaces former local file.
Advantage: easy to operate, bandwidth consumption is small.
Disadvantage: it is required that operating system and network environment are normal.
(2) pass through recovery installing firmware
Process: being downloaded complete firmware by user manually, and preservation is brushed to local into recovery into firmware.
Advantage: can be with prosthetic appliance in the case where operating system is not normally functioning.
Disadvantage: needing user to download firmware manually, consumes to server bandwidth big.And require subregion that cannot damage.
(3) computer controls burning
Process: being downloaded complete firmware by user manually, is saved to computer, is connected equipment, pass through special burn recording software
It brushes into firmware.
Advantage: can be with prosthetic appliance in the case where subregion damage.
Disadvantage: needing user to download firmware manually, consumes to server bandwidth big.And it is cumbersome.
But these three mainstream autonomous repair technologies require locally keeping complete firmware in advance, but also bring along volume
Outer unnecessary expense, increases the cost of product.
Summary of the invention
The technical issues of present invention provides a kind of self-regeneration method of embedded device, solution be, existing embedded to set
Standby the autonomous repair technology of use requires locally keeping complete firmware in advance in the case where subregion damage, brings
Additional unnecessary expense, increases the cost of product.
In order to solve the above technical problems, the present invention provides a kind of self-regeneration method of embedded device, including following step
It is rapid:
S1. P2P network is established using index server as source node in advance；
S2. embedded device is opened；
S3. judge whether subregion has been damaged, if so then execute next step, if otherwise guiding os starting；
S4. self-regeneration file is downloaded by the P2P network and carries out self-regeneration.
Further, the step S1 is specifically included:
S1-1. index server is established, for providing TFTP service；
S1-2. the index server is built into P2P framework as source node, shared terminal as non-source node
DHT network.
Further, the step S4 is specifically included:
S4-1. it connects the index server and the P2P network is added, become one of node；
S4-2. the node that the shared subfile for having the self-regeneration file is found in the P2P network, is enjoyed together
The node of the subfile establishes connection and downloads the self-regeneration file；
S4-3. it parses the self-regeneration file and carries out self-regeneration.
Further, the step S4-2 is specifically included:
S4-21. it is searched and the self-regeneration in the shared file in the non-source node by TFTP service
The subfile that file matches；
S4-22. the non-source node for enjoying the subfile together establishes downloading connection, and starts to download；
S4-23. judge whether the subfile required for the self-regeneration file all can be from the non-source node
Middle downloading, if then the subfile of downloading is stored in same memory；If otherwise found in the source node it is described self
The remaining subfile of file is repaired, is stored in after downloading in the same memory；
S4-24. confirm whether comprising all subfiles in the self-regeneration file in the same memory, if then
Exit the TFTP service；If otherwise returning to the step S4-21, until confirm in the same memory comprising it is described self
All subfiles in file are repaired, and TFTP described in backed off after random is serviced.
Further, the step S4-3 is specifically included:
S4-31. nand flash subarea is formatted；
S4-32. subregion is written into the self-regeneration file in the same memory；
S4-33. the os starting of the self-regeneration file is written in guidance.
Further, in the step S4-1, the index server is connected specifically: the rope is obtained by DNS
The IP address for drawing server establishes connection by accessing the IP address and the index server.
The self-regeneration method of a kind of embedded device provided by the invention, especially suitable for embedded Android device.
A kind of self-regeneration method of embedded device provided by the invention cannot be opened in subregion damage or operating system
In the case where dynamic, using P2P network share mode, damage subregion is obtained by each node of its network service in P2P network
Required reparation file simultaneously repairs subregion, does not need locally keeping complete reparation file in advance, avoids bringing additional
Unnecessary expense, save the cost.
