Embodiment
By describe in detail technical scheme technology contents, structural attitude, realized object and effect, coordinate accompanying drawing to be explained in detail below in conjunction with specific embodiment.
Refer to Fig. 1 and Fig. 2, Fig. 1 shows the data programming system that the embodiment of the present invention provides, the target device that described data programming system comprises burn writing equipment and is connected with described burn writing equipment, can data communication between described burn writing equipment and target device, burn writing equipment can will treat that programming data or firmware programming are in target device.In concrete enforcement, burn writing equipment can for having firmware or data programming to the embedded device in other equipment or PC equipment or data flashburn tools/device of being installed in equipment, and described target device can be mobile terminal, embedded device, PC equipment and the mainboard with memory module and central processing unit.
Refer to Fig. 2, Fig. 2 shows the data programming method of the embodiment of the present invention based on data programming system, comprising:
S202, burn writing equipment generate treats the segmentation checking data of programming data, to target device, the programming of described segmentation checking data is judged that described segmentation checking data is by correct programming; Wherein, described segmentation checking data comprise according to described in treats the segments that programming data are divided, the first check information corresponding to programming data, initial LBA address and data block size are treated in each segmentation;
By described, S204, described burn writing equipment treat that the programming of programming data is to described target device;
S206, described target device generate and treat the target programming data that programming data are corresponding, generate the second check information corresponding to described target programming data according to described segmentation checking data; Wherein, described second check information is according to described segments, the check information that each segmented objects programming data are corresponding;
First check information, the second check information described in S208, described target device comparison, determine comparison result, and described comparison result be sent to described burn writing equipment.
Here, one skilled in the art will appreciate that the first check information comprises multiple check information, corresponding segments treats programming data respectively; Second check information comprises multiple check information equally, respectively corresponding each segmented objects programming data.Concrete, whether the first check information described in comparison, the second check information be consistent.If consistent, then described comparison result is successfully; If inconsistent, then comparative result is unsuccessfully.Wherein, described comparison result for represent each segmentation that the first check information is corresponding treat programming data whether by correct programming to target device.At specific embodiment, if comparison result is successfully, then show to treat programming data by correct programming to target device; If comparison result is unsuccessfully, then the segmentation that the check information that in the first/the second check information, comparison is inconsistent is corresponding treat programming data not by correct programming to target device.
The embodiment of the present invention is by second check information more corresponding than each segmented objects programming data of each segmentation treating programming data target programming data after the first check information corresponding to programming data and programming, treat described in determining programming data whether by correctly programming to target device, and comparison result is sent to burn writing equipment.The first check information due to embodiment of the present invention comparison is that programming data are treated in corresponding each segmentation, namely what then comparison result was corresponding is that each segmentation treats that whether programming data are all by correct programming, according to comparison result, burn writing equipment just can judge which segmentation treats programming data not by correct programming.In order to more clearly explain above-mentioned principle, for example bright below.Suppose to treat that programming data are a data firmware with 1GB data volume, after systematic analysis, set this data firmware be divided into 4 sections, namely segments is 4.
The setting of this segments can set according to the factor such as size, the efficiency of system process, the time of programming DATA POPULATION of data firmware automatically for burn writing equipment; Also can be burn writing equipment receive outside input and establish, it is 4 that such as user inputs this segments by burn writing equipment; Also can according to the processor quantity set of target device, such as target device is four nuclear equipments, then this segments can be 4.
S202, generally, burn writing equipment to treat that according to segments 4 blocks such as programming data divide, and obtains multiple segmentation and treat programming data.Certainly, burn writing equipment also can not will treat that the blocks such as programming data divide, as long as treat programming data by treating that programming Data Placement becomes with multiple segmentations of segments equal number.After dividing, burn writing equipment can get initial LBA address and the data block size that programming data are treated in each segmentation, and treats that programming data carry out verify calculation to each segmentation, obtains the first corresponding check information.Concrete, can treat that programming data carry out CRC algorithm calculating to each segmentation, obtain a CRC numerical value.After above-mentioned, burn writing equipment can obtain the segmentation checking data treating programming data, as shown in table 1 below.At specific embodiment, the form of expression of this segmentation checking data can be data layout as shown in table 1.For convenience of description, following form is to treat that programming data are waited block to divide, and address offset amount is that segmentation treats that programming size of data (i.e. 256MB) is example.
Table 1
After described segmentation checking data generates, burn writing equipment by the programming of described segmentation checking data to target device.In order to just as explanation, that suppose the original generation of burn writing equipment is segmentation checking data A, target device by programming for segmentation checking data B, burn writing equipment obtains described segmentation checking data B to target device, and compares one by one with the segmentation checking data A of original generation.If B is completely the same for segmentation checking data A, segmentation checking data, then show segmentation checking data A by correct programming to target device.If segmentation checking data A and segmentation checking data B is also not quite identical, then show that segmentation checking data A does not have by correct programming to target device.Now, burn writing equipment can again by the programming of segmentation checking data to target device, and carry out contrast judgement, until treat segmentation checking data by correct programming to target device.
S204, segmentation checking data are by after correct programming to target device, by described, burn writing equipment treats that the programming of programming data is to target device.
S206, target device, by after programming data, obtain corresponding target programming data.The second check information corresponding to target programming data is generated according to segmentation checking data.Concrete, according to the data of each segmentation in the acquisition of information target programming data such as the LBA start address enumerated in segmentation checking data, data block size, i.e. each segmented objects programming data.Target device carries out verify calculation by checking algorithm to each segmented objects programming data again, such as, carry out verify calculation by CRC algorithm to each segmented objects programming data, generates the 2nd CRC numerical value that each segmented objects programming data are corresponding, i.e. the second check information.The second check information obtained can be as shown in table 2 below.
Table 2
Target device is a CRC1-4, the 2nd CRC1-4 described in corresponding comparison respectively, generates comparison result.Described comparison result can be as shown in table 3 below.
Table 3
Described comparison result is sent to burn writing equipment by S208, target device.
Can know clearly after burn writing equipment receives this comparison result which blocks of data treating programming data is not by correct programming.Burn writing equipment treats the total data of programming data without the need to programming again, and only programming, not by the data of correct programming (as programming data 3,4 are treated in the segmentation in foregoing description), improves data programming efficiency, saved cost again.Concrete, burn writing equipment can determine after receiving comparison result that programming data are treated in the segmentation of failure, thus determines that programming data are treated in corresponding failed segmentation, and the segmentation for failure treats that programming data re-start above-mentioned programming process.
In order to programming data are treated in the segmentation that burn writing equipment can be made to look for programming failure quickly, in the further improvement of the embodiment of the present invention, target device also can delete the successful segmentation checking data of comparison, the segmentation checking data of comparison failure is preserved, and only the segmentation checking data of comparison failure is sent to burn writing equipment.Burn writing equipment can find corresponding failed segmentation to treat programming data according to the segmentation checking data of comparison failure rapidly.Based on illustrating above, the segmentation checking data of comparison failure is as shown in table 4 below.
Table 4
| Source segment data sequence number | First check information | Initial LBA address | Data block size |
| Programming data 3 are treated in segmentation | One CRC3 | One LBA address+512MB | 256MB |
| Programming data 4 are treated in segmentation | One CRC4 | One LBA address+768MB | 256MB |
Refer to Fig. 1 and Fig. 3, the present embodiment provides a kind of data programming method, the method be applied to comprise as shown in Figure 1 burn writing equipment, target device data programming system, described in data programming system shown in Fig. 1 describes and can refer to above, do not repeat them here.In the present embodiment, described in treat that programming data are the system image of a firmware, it has boot.Fig. 3 illustrates the sequential process flow diagram of data programming method, and concrete scheme is as follows.
(1) burn writing equipment first reads the boot treated in the firmware of programming, calculates the CRC numerical value (i.e. the 4th check information) of boot, starts this boot of programming in the main memory of target device.Boot in retaking of a year or grade main memory the CRC numerical value (the 5th check information) calculating the boot that retaking of a year or grade is returned compare, if consistent, show boot programming success.
(2) burn writing equipment reads the system image (namely treating programming data) treating programming, and receive the segments of the system image of producers' input, staging treating is carried out to described system image, obtains multiple segmented system mirror image (namely programming data are treated in segmentation).Burn writing equipment calculates the CRC numerical value (i.e. the first check information) of each segmented system mirror image of this system image respectively, be recorded as list data (i.e. segmentation checking data), the form of list data is the initial LBA address of this segmented system mirror image and the data block size of this segmented system mirror image, and the CRC numerical value of correspondence.Concrete form can consult table 1 above.
(3) burn writing equipment is by this list data programming in the main memory of target device, and this form of retaking of a year or grade, this list data preserved with burn writing equipment this locality compares, and guarantees that list data programming is correct.Concrete, that suppose that burn writing equipment retaking of a year or grade returns is list data B, and the original list data of the local storage of burn writing equipment is list data A.If list data A and list data B is completely the same, then show list data A by correctly programming to target device.Otherwise, need again programming list data A to target device, and again multilevel iudge list data A whether by correct programming to target device.
(4) burn writing equipment is by the programming of whole system mirror image as in the main memory of target device, and target device generates corresponding goal systems mirror image (i.e. target programming data).
(5) burn writing equipment sends reset command to target device.Target device restarts also load operating boot, and (step (1) programming verifies, can guarantee correct), boot is according to the field (form described in step (2)) enumerated in list data (step (2) produces), the each segmented objects system image (namely segmented objects treats programming data) reading target device this locality successively calculates CRC numerical value (i.e. the second check information), and the real CRC numerical value of this segmented objects system image (i.e. the first check information) compares in list data.If comparative result difference, show this segmented system mirror image programming mistake; If comparative result is identical, show that this segmented system mirror image programming is correct, concrete, table 3 above can be consulted.Further, target device also can by list data, and the segment information of verification succeeds is deleted, and only retains the failed segment information (i.e. the segmentation checking data of comparison failure) of verification.If each segmented system mirror image verification all successes, then the list data in target device main memory is all deleted complete.
(6) suppose that having some segment data to verify finds that programming have failed more afterwards, the information that then this segment data is corresponding can be remained (as described in step (5) by target device in described list data, the corresponding informance of the segmented system mirror image of success programming all can be deleted, the corresponding informance having the segmented system mirror image of programming failure only can be retained), and send to burn writing equipment.
(7) burn writing equipment receives the list data of target device passback, according to the residual term (information of the segmented system mirror image of programming failure described namely, comprise the LBA address of this segmented system mirror image, size, CRC check value), this segmented system mirror image of independent programming, need not the whole system mirror data of programming again.
(8) before, failed segment data is by after programming again, target device also can according to the list data information (part charge of the corresponding last programming failure of residual list data information residual before, the namely part charge of this programming more corresponding, the i.e. segmentation checking data of comparison failure), calculate the CRC numerical value (the 3rd check information) of the segmented system mirror image of this programming, compare.According to described mode before, write as merit if reburned, then delete to reburn in residual list data information and write successful segmented system Mirror Info, if failure, continue to retain this information, finally send to burn writing equipment again.
The like, circulate from step (7), until all segmented system mirror images are by entirely true programming success.
