embodiment bis-:
Fig. 4 shows the realization flow of the partition table data updating method that second embodiment of the invention provides, and these partition table data generate the data in partition table file for the step by above-described embodiment one, and details are as follows:
In step S401, whether the new partition table file that judgement gets is identical with current partition table file, is, performs step S402, no, performs step S405, keeps this current partition table file constant;
In step S402, according to attribute bit descriptor in the descriptor of this current partition table file, read protected partition data to extra buffer.
In step S403, upgrading this current partition table file is this new partition table file.
In step S404, this protected partition data in this extra buffer is write again in the attribute bit descriptor of descriptor of this current partition table file.
In the software version update replacement process of veneer, situation about changing is planned in the use that likely occurs flash, now, may there is difference in some critical data address and former and later two versions of size definition on flash, the partition address that will look for novelty like this still can correctly read the data of old partition address.
The partition table data updating method that the embodiment of the present invention provides or the title flash partition protecting upgrading flow process based on partition table mechanism can meet this requirement.Particularly; new partition table file is passed to upgrading module as first image; whether newer partition table file is identical with current already present partition table file (old partition table); if it is not identical; first read in current partition table file protected data temporary to extra buffer, data in this current partition table file whether protected in the descriptor of current partition table file attribute bit descriptor decide.Reading protected partition data to extra buffer; can utilize new partition table file to replace current partition table file in flash driving; again the temporary protected data of extra buffer is write back in flash; at this time destination address is the address of new table subregion; also use corresponding data in the new table of protected data replacement; realized the object of the male cousin's data that drive with new table data replacement flash; further, by above-mentioned steps, can continue the upgrading write operation of other subregion mirror images.Thereby the comparison of the embodiment of the present invention by the old and new's subregion can realize two critical datas between different editions and protect.
Further, as shown in Figure 5, this partition table data updating method also comprises:
In step S501, in the electrifying startup stage, by boot loader, from flash fixed address, obtain partition table file.
In step S502, according to the attribute bit descriptor in the descriptor of this partition table file, judge whether partition data is valid data, is, performs step S503, no, perform step S504.
In step S503, obtain the partition data that flash fixed address is preserved.
In step S504, obtain the partition data that the partition table symbol content in executable image comprises.
In step S505, effective partition data is left in shared drive.
In the electrifying startup stage of veneer, partition table file is activated loading procedure and reads out from the fixed address of flash, head zone bit by judgement partition data is identified the validity of partition data, be specially by with each partition table file in the zone attribute position of each subregion data validity attribute in describing identify.If this partition data is effective, the partition data that preferentially obtains and use flash fixed address to preserve, if this partition data is invalid, the partition table data of using compiling link to be comprised to the partition table symbol content inside executable image (as bootloader).Wherein, these partition table data are as preliminary data, the difference of the partition data of preserving with fixed address is above: it is a default value that the partition data of list item the inside takies size, this default value is larger than the actual valid data of subregion, and the partition data of the data table items that flash fixed address is preserved the inside takies size and the actual valid data of subregion are in the same size.Further effective partition data is stored in to veneer shared drive, access when starting for a plurality of core.
In embodiments of the present invention, based on above-mentioned steps, this partition table data updating method also further comprises:
At multinuclear, access in the situation of single flash space, at each core, be loaded after startup, each is checked the flash driver of answering and from this veneer shared drive, reads this effective partition data, and this effective partition data is changed and saved as and check with each the flash answering and drive adaptive activation bit.
Particularly, multinuclear is accessed in the situation of single flash space, each core is loaded after startup, they can read public partition table data by flash driver separately from above-mentioned shared drive, also read effective partition data, and the flash that these partition data information are changed and saved as separately drives adaptive partition information, such as saving as linux, be converted to MTD partition data information etc.

embodiment tri-:
Fig. 6 shows the realization flow of the partition table data updating method that third embodiment of the invention provides, and these partition table data generate the data in partition table file for the step by above-described embodiment one, and details are as follows:
In embodiments of the present invention, after the use providing based on above-described embodiment two is newly shown the partition table data upgrading of male cousin's data that data replacement flash drives, this partition table data updating method also comprises the steps:
In step S601, whether judgement has in the descriptor that a plurality of subregions of identical partitions functional identity, different zone name are corresponding subregion count value all identical, is, performs step S602, no, performs step S603.
In step S602, it is efficient zoned that the most front subregion of skew first address is set, and other non-effective subregions are backup subregion.
In step S603, the subregion that subregion count value maximum is set is efficient zoned, and other non-effective subregions are backup subregion.
In specific implementation process, with subregion count value unit in the descriptor of subregion, usually realize many back mechanisms of the subregion with identical partitions functional identity.For a plurality of subregions with identical partitions functional identity, different zone name, the subregion value initial value of each subregion is 0.
When edition upgrading, always get older subregion (subregion count value the is less) renewal of upgrading, it is efficient zoned that this subregion is further set, and is always getting newer subregion (subregion count value is larger) as efficient zoned in formal use.Such as, to plan two subregions with identical partitions functional identity, but the zone name of two subregions is not all example, but is not limited to this example.The subregion count value initial value of these two subregions is all 0.Now judge the subregion count value that these two subregions are corresponding identical, it is efficient zoned adopting forward subregion, and the most front subregion of skew first address is also set is efficient zoned, and other non-effective subregions are backup subregion.Afterwards, the subregion count value that these two subregions are corresponding is no longer identical, and the subregion that subregion count value maximum is set is efficient zoned, and other non-effective subregions are backup subregion.
In addition, when carrying out subregion upgrading, this partition table data updating method also comprises:
The subregion of regeneration block count value minimum is maximal value, and this maximal value is that current efficient zoned subregion count value adds the value after 1;
The subregion that subregion count value maximum corresponding in current a plurality of subregion is set is efficient zoned, and other non-effective subregions are backup subregion.
Particularly, when subregion is upgraded, invalid partition data or claim non-effective partition data can be searched to and write, corresponding subregion count value can be set as maximal value simultaneously, this maximal value is that current efficient zoned subregion count value adds the value after 1, in current a plurality of subregions after arranging, the subregion of corresponding subregion count value maximum is efficient zoned, and other non-effective subregions are backup subregion.If upgrading, can find older subregion according to count value again again, carry out Data Update, become new efficient zoned.By that analogy, the partition data before always upgrading last time of backup partition data.
One of ordinary skill in the art will appreciate that all or part of step realizing in above-described embodiment method is to come the hardware that instruction is relevant to complete by program, described program can be stored in a computer read/write memory medium, described storage medium, as ROM/RAM, disk, CD etc.
