Firstly, in the embodiment of the present application, an EMMC adaptive upgrade method is provided, an execution subject of the EMMC adaptive upgrade method is an EMMC adaptive upgrade apparatus, the EMMC adaptive upgrade apparatus is applied to a computer device, and the EMMC adaptive upgrade method includes: acquiring a first capacity of an EMMC and a preset upgrade package, wherein the upgrade package is a preset upgrade file for upgrading the EMMC, the upgrade package comprises a plurality of partitions, and the plurality of partitions comprise user data partitions; acquiring a second capacity of the upgrade package, and comparing a difference value between the first capacity and the second capacity with a preset capacity threshold, wherein the second capacity is the sum of the capacities of all the partitions in the upgrade package; and when the difference value between the first capacity and the second capacity is larger than the capacity threshold, adjusting the user data partition according to the first capacity and the capacity threshold so as to realize the self-adaptive upgrading of the EMMC.
Fig. 2 is a schematic flow chart of an embodiment of an EMMC adaptive upgrade method according to an embodiment of the present application, where the EMMC adaptive upgrade method includes:
s100, acquiring a first capacity of the EMMC and a preset upgrade package, wherein the upgrade package is a preset upgrade file for upgrading the EMMC, the upgrade package comprises a plurality of partitions, and the partitions comprise user data partitions.
An embedded multimedia card (English full name: embeded Multi Media Card, abbreviated to EMMC) is established by the MMC society, and is mainly aimed at the standard specification of an embedded memory of a mobile electronic product such as a mobile phone or a tablet computer. The EMMC consists of an embedded memory solution, in which a controller is integrated in a package, providing a standard interface and managing flash memory, with a multimedia Card (english: multi Media Card, abbreviated: MMC) interface, a flash memory device and a main controller, the EMMC being an EMMC configured by a device, for example, the EMMC configured by the computer device 100 in fig. 1, the first capacity being the actual capacity of the EMMC, and the EMMC of different capacities being configured by the same product series depending on the location of the device, for example, 8G, 16G, 32G, etc.
The preset upgrade package is a preset upgrade file for upgrading the EMMC, the preset upgrade package can be obtained from the upgrade file of the device for configuring the EMMC, and upgrade packages with different capacities are generally configured in the traditional upgrade file, but in order to reduce the data volume and the software maintenance cost of the upgrade file, the same upgrade package is used for the EMMC with the same series of EMMCs with different capacities, and the preset upgrade package is the upgrade package corresponding to the EMMC with the smallest capacity in the EMMC with the same series of EMMCs with different capacities. The upgrade package includes a plurality of Partitions, and the plurality of Partitions may include, besides a User Data partition (User Data Area), other Partitions such as a startup partition (Boot Area Partitions), a User encryption and decryption User partition (Replay Protected Memory Block Partitions, RPMB Partitions), a general partition (General Purpose Partitions, GPP), and the like.
Because the same upgrade package is used by the same series of EMMCs with different capacities, the preset upgrade package is not necessarily adapted to the EMMCs, in order to achieve adaptive upgrade of the EMMCs, in this embodiment, first capacity of the EMMCs and the preset upgrade package are obtained first, so that in a subsequent step, whether the preset upgrade package is adapted to the EMMCs is judged according to the first capacity, that is, whether a plurality of partitions in the upgrade package are normal with respect to the EMMCs, and in the case that the partition of the plurality of partitions is abnormal, user data partitions in the upgrade package are adjusted, so that the preset upgrade package is adapted to the EMMCs.
In a specific embodiment, in step S100, the step of obtaining the first capacity of the EMMC includes:
s110, calling a preset self-adaptive function to initialize the EMMC, and acquiring a first capacity of the EMMC through the initialization of the EMMC.
In this embodiment, an adaptive function for acquiring the first capacity is preset, and when the first capacity of the EMMC needs to be acquired, the preset adaptive function is called to initialize the EMMC, and in the process of initializing the EMMC by the adaptive function, the adaptive function may call the EMMC driver, and the first capacity of the EMMC is acquired by calling the EMMC driver to read a register in the EMMC. For example, when the device is based on a Uboot system starting architecture, an emmc_self_adaptation function may be added to the Uboot and packaged in a CMD form, and when the first capacity of the EMMC needs to be obtained, the first capacity of the EMMC may be obtained by calling the emmc_self_adaptation function to initialize the EMMC.
S200, obtaining a second capacity of the upgrade package, and comparing a difference value between the first capacity and the second capacity with a preset capacity threshold, wherein the second capacity is a sum of capacities of all partitions in the upgrade package.
The second capacity is the sum of the capacities of all the partitions in the upgrade package, for example, when the upgrade package comprises a startup partition, a user encryption and decryption user partition, a general partition and a user data partition, the second capacity is the sum of the capacities of the startup partition, the user encryption and decryption user partition, the general partition and the user data partition. The capacity threshold is a preset capacity threshold for measuring whether a plurality of partitions in the upgrade package divide a normal capacity, and the inventor finds that for EMMC with capacity of 4G to 128G, the reserved capacity is different from 50M to 1024M, that is, the preset capacity threshold is 1% of the first capacity.
In this embodiment, after the first capacity and the preset upgrade package are acquired, the second capacity of the upgrade package is acquired, a difference value between the first capacity and the second capacity is compared with a preset threshold value, and whether a plurality of partitions in the upgrade package are normally divided is determined according to a comparison result between the difference value between the first capacity and the second capacity and the preset threshold value. For example, when the first capacity is T1 and the second capacity is T2, and the preset capacity threshold is P, comparing the difference between the first capacity and the second capacity, i.e., T1-T2, and the preset capacity threshold P, and determining whether the division of the plurality of partitions in the upgrade package is normal according to the comparison result.
In a specific embodiment, in step S200, the step of obtaining the second capacity of the upgrade package includes:
s210, obtaining third capacity of each partition in the upgrade package;
s220, determining the second capacity of the upgrade package according to the third capacity.
The upgrade package includes a plurality of partitions, each partition has its corresponding capacity, for example, the capacity of the boot area partition and the user encryption and decryption user partition is typically 4MB, and the capacity of the user data partition is typically the total capacity minus the capacities occupied by other partitions. In order to obtain the second capacity of the upgrade package, that is, the sum of the capacities of all the partitions in the upgrade package, the embodiment first obtains the third capacity of each partition in the upgrade package, and then adds the third capacities of each partition to obtain the second capacity of the upgrade package.
And S300, when the difference value between the first capacity and the second capacity is larger than the capacity threshold, adjusting the user data partition according to the first capacity and the capacity threshold so as to realize the self-adaptive upgrading of the EMMC.
The difference value between the first capacity and the second capacity represents the difference value between the actual capacity of the EMMC and the partition capacity, and when the difference value between the first capacity and the second capacity is not greater than the capacity threshold value, the difference value indicates that the partition capacity in the preset upgrade package is normally partitioned, and the EMMC can directly use the upgrade package to upgrade without adjusting the user data partition. When the difference between the first capacity and the second capacity is greater than the capacity threshold, it indicates that the capacity of the partition divided in the preset upgrade package is smaller than the actual capacity of the EMMC, and the user data partition needs to be adjusted.
Typically, the capacity of the other partitions of the several partitions except the user data partition is fixed, for example, the capacity of the boot partition and the user encryption and decryption user partition is typically 4MB. In this embodiment, when the difference between the first capacity and the second capacity is greater than a capacity threshold, that is, the capacity of the partition divided in the preset upgrade package is smaller than the actual capacity of the EMMC, the user data partition is adjusted according to the first capacity and the capacity threshold, so as to implement adaptive upgrade of the EMMC.
In one embodiment, the step of adjusting the user data partition according to the first capacity and the capacity threshold in step S300 includes:
s310, re-dividing the user data partition according to the first capacity and the capacity threshold;
s320, writing the user partition data in the user data partition backed up in advance into the user data partition after repartitioning.
The user partition data is data stored in the user data partition, when the difference between the first capacity and the second capacity is greater than the capacity threshold, the embodiment reclassifies the user data partition according to the first capacity and the capacity threshold, and writes the user partition data backed up in advance into the reclassifed user data partition, so that the EMMC can be upgraded by using a preset upgrade package, thereby realizing the adaptive upgrade of the EMMC.
In one embodiment, step S310 includes:
s311, obtaining a third capacity of the upgrade package, wherein the third capacity is the sum of the capacities of all the partitions except the user data partition in the upgrade package;
s312, the user data partition is divided again according to the third capacity, the first capacity and the capacity threshold.
The third capacity is the sum of the capacities of all the partitions except the user data partition in the upgrade package, for example, when the partitions comprise the user data partition, the starting partition, the user encryption and decryption user partition and the universal partition, the third capacity is the sum of the capacities of the starting partition, the user encryption and decryption user partition and the universal partition. When the user data partition is re-divided, the third capacity of the upgrade package is obtained first, and then the user data partition is re-divided according to the third capacity, the first capacity and the capacity threshold value, so as to realize the self-adaptive upgrade of the EMMC.
In one embodiment, step S312 includes:
s3121, determining a fourth capacity according to the third capacity, the first capacity and the capacity threshold;
and S3122, re-dividing the user data partition according to the fourth capacity.
The fourth capacity is the difference value between the third capacity, the first capacity and the capacity threshold, the calculation formula of the fourth capacity is T4=T1-T2-P, wherein T4 is the fourth capacity, T1 is the first capacity, T2 is the second capacity, and P is the capacity threshold. When the user data partition is re-divided, the fourth capacity is first determined according to the third capacity, the first capacity and the capacity threshold, and then the fourth capacity is used as the capacity of the user data partition to re-divide the user data partition.
In a specific embodiment, before step S310, the method further includes:
s301, acquiring user partition data stored in the user data partition;
s302, backing up the user partition data.
In order to avoid the loss of the user partition data stored in the user data partition, the embodiment acquires the user partition data stored in the user data partition, backs up the user partition data, and erases the user partition data in the user partition data before the user data partition is re-divided according to the first capacity and the capacity threshold. For example, when the device starts the architecture based on the Uboot system, the device enters a recovery mode to erase the user partition data in the user partition data.
In order to better implement the EMMC self-adaptive upgrade method in the embodiment of the present application, on the basis of the EMMC self-adaptive upgrade method, the embodiment of the present application further provides an EMMC self-adaptive upgrade apparatus, as shown in fig. 3, where the EMMC self-adaptive upgrade apparatus 600 includes:
