Please referring to Fig. 1, be the structural representation of the guidance system of a kind of embedded system of first embodiment of the invention.
Embedded system guidance system provided by the invention comprises scalable guiding subsystem 1 and basic guiding subsystem 2.
Described scalable guiding subsystem 1 comprises: scalable boot, and (the concrete memory element in the present embodiment is FLASHMEMORY to deposit the memory element of the embedded system of this program, flash memory, abbreviation FLASH) first storage area, its address space is FFF80000～FFFFFFFF, take four pieces (Block, each piece comprises the 1024K byte).
Described basic guiding subsystem 2 comprises: basic boot, and second storage area of FLASH of depositing the embedded system of this program, its address space is FFF00000～FFF7FFFF, takies four pieces.
In other address space FF800000～FFFEFFFF of the FLASH of described embedded system, deposited application program.This part program does not belong to this embedded system bootstrap program.
Described scalable boot is used to realize main system boot functions, it comprises that MAC/SN (network identity/product mark) verification, FTS (test procedure in the production) program designation, the verification of Application Image (application program) legitimacy, TFTP SERVER (network transmission protocol) start, Command Line Interface (CLI, Command Line Interface), functional module such as Application Image (application program) guiding.Store the protection that the storage area of this scalable boot is not latched by hardware, the user can carry out write operation to this zone by the boot upgrade interface among the Application Image, realizes the upgrading to scalable boot.
Described basic boot comprises POST (Power On SelfTest, power-on self-test is surveyed), functional modules such as the verification of scalable boot legitimacy, MAC/SN verification, FTS program designation, the verification of Application Image legitimacy, TFTP SERVER startup, CLI, Application Image guiding.Simultaneously, (FFF00000～FFF80000) locked by hardware (BLOCK LOCK) is unless after at first using corresponding unlocking program (BLOCK UNLOCK) release, just can carry out write operation to this zone for second storage area at basic boot place.Above-mentioned measure guarantees that basic boot remains good working condition.Certainly, do not get rid of by CLI, by CLI basic boot is upgraded then the described second storage area release.Under normal circumstances, when carrying out system bootstrap, each functional module of this basic boot is all operations not, but after modules such as operation POST (Power On SelfTest), the verification of scalable boot legitimacy, if through the scalable boot of checking proof is legal, then scalable boot is transferred in the control of system, finished system boot functions by scalable boot.
Although in the present embodiment, the storage area at basic boot place is locked by hardware, but also can not carry out hardware in actual the use locks, at this moment, the effect of basic boot is to have prepared a backup for boot, can section upgrade boot when being damaged in support.
The guidance system of the embedded system of present embodiment, for the user provides the scalable boot that can conveniently upgrade, the user can be as requested easily to its upgrading, make the effect of this embedded system of performance that the user can be maximum.Simultaneously; the guidance system of this embedded system is subjected to the basic boot of hardware locking protection for the user provides storage area again; in the time of can guaranteeing that this embedded system maloperation or other reason occur and causes scalable boot destroyed, by the ultimate system guiding down program realize guiding to this embedded system.
Please referring to Fig. 2, this figure is an embedded system bootstrap technique provided by the invention.This bootstrap technique is realized by the operation of described boot.
Step S200, beginning, embedded system powers on.
Step S201 loads the initial part and wherein the POST of operation of basic boot.
After described embedded system powered on, at first load store was in the initial part and the operation of the basic boot of the particular memory region of FLASH.Described basic boot is at first carried out Power-On Self-Test program (Power On SelfTest) after this embedded system powers on, this program detects the hardware of embedded OS.After detection shows that the hardware of embedded system is intact, enter next step.If there is fault in hardware system, then crashes and report to the police.
Whether step S202 checks described scalable boot to exist.If enter step S203; If not, then enter step S205.
Described scalable boot at this moment, will be finished guiding function by each functional module of basic boot self because a variety of causes may reality not exist.If described scalable boot exists, then should use scalable boot to finish guiding function.This be because, scalable boot can be upgraded at any time by the user, can make embedded system have better operational effect.
The method that under prior art, has the described scalable boot of the above-mentioned check of multiple realization whether to exist.For example, certain zone bit is set, this zone bit carries out set after described scalable boot is mounted, and consults for basic boot.
Whether step S203 checks described scalable boot complete correct.If then enter step S204; If not, then enter step S205.
After check shows that this scalable boot exists, also need the further integrality and the correctness of the described scalable boot of check, this is because scalable boot can easier be rewritten, therefore might be damaged, for avoiding the impaired scalable boot of operation, should test to this program.
The integrality of the scalable boot of described check, specifically be by MD5 (Message-DigestAlgorithm5, realize that md5-challenge) this algorithm can produce informative abstract (Message-Digest) to a segment information, to prevent that this segment information from being distorted.
Step S204 loads described scalable boot, and uses this program to finish system bootstrap.Whole bootup process finishes, and enters step S210.
Step S205 loads the remainder of described basic boot, and uses basic boot to finish system bootstrap.
After finishing system bootstrap, the kernel of operating system control is called, and realizes guiding and loads kernel.The task of guidance system is finished, but because described scalable boot is in abnormal state of affairs, is necessary this is carried out some processing.For this reason, carry out following step.
Step S206 judges whether application program (Application Image) is complete correct.If then enter step S207; If not, then enter step 208.
The application software of described embedded system has the upgrading page, and the user can be under the indication of this page of upgrading, and realizes upgrading to described scalable boot by remote access mode.
If described application program is complete correct, then can directly uses the upgrading of the upgrading page realization of this application program, thereby finish recovery and upgrading scalable boot to scalable boot.If application program is imperfect, then can not use this page upgrading mode, in order to avoid make mistakes.
The above-mentioned upgrading page also can be advanced into after the embedded system operate as normal certainly by the user, at any time guidance system is upgraded.
Step S207 recovers the described scalable helical pitch preface of answering by the upgrading page.
The described upgrading page, be actually of entering that this embedded system application program provides be used to realize the to upgrade page of described scalable boot, the user is under the guiding of this page, the relevant website of control embedded system visit, perhaps obtain scalable boot and download from other approach, the program that is downloaded can be written in the particular memory region of described scalable guiding subsystem, finally finishes the upgrading to scalable boot.At this, use this page to finish to being damaged or as yet not by the recovery or the installation of scalable boot of dress.After this step was finished, scalable boot was just recovered to finish, and enters step S210.
Under the situation of the normal operation of embedded system, also can enter the described upgrading page, by downloading the redaction of scalable boot, realize upgrading to scalable boot.
Step S208, and startup command row interface (Commond Line Interface, CLI).
The interface of described Command Line Interface this embedded system of rewriting FLASH content that to be described embedded system provide by serial line interface.Can manually rewrite the content of the FLASH of embedded system by this interface.If do not need to carry out the Command Line Interface upgrading, also can withdraw from this interface, directly enter step S210.
Step S209, the described scalable boot of upgrading.
After entering the CLI interface, adopt the manually method of input, by the upgrading of described CLI interface with recover described scalable boot.This upgrading and reset mode more complicated, and go wrong easily, therefore generally need be undertaken by producer.Owing to need the situation of manually upgrading more rare, therefore, when occurring destroying, generally can realize the recovery and the upgrading of system by page upgrading mode for scalable boot.
Step S210 finishes, and enters application program.
It is a kind of function that FLASH producer provides that FLASH is carried out the hardware locking protection.Use this function to realize that for unit hardware locks according to piece (Block, each piece comprises the 1024K byte) to FLSASH.Present most embedded OS does not lock to the FLASH address of depositing boot, and this is because the user that can make who locks is difficult to voluntarily boot be upgraded.The problem that causes thus is that boot might be destroyed by maloperation.
Method provided by the invention is owing to have scalable guiding subsystem 1 and basic guiding subsystem 2, therefore, can carry out hardware to the FLASH address area of basic guiding subsystem 2 locks, and not carried out hardware, the FLASH address at scalable guiding subsystem 1 place do not add latching operation, be not destroyed thereby reach the system of assurance, and at any time can purpose of upgrading.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
