Problems solved by technology

[0003] During the use of smart terminals, various suspected EMMC damages often occur. For example, if the mobile phone password cannot be verified, the after-sales maintenance personnel must first determine whether the password entered by the user cannot be stored in the EMMC due to EMMC damage. The password is verified, so that the password cannot be verified, and the smart terminal cannot be used
However, in the prior art, since determining whether the EMMC is damaged requires additional testing equipment, and the testing equipment is expensive, most after-sales maintenance points do not have testing equipment, and the after-sales maintenance personnel will directly replace the EMMC when determining whether the EMMC is damaged.
[0004] However, the above method will cause EMMC to be replaced in many cases where there is no need to replace the EMMC. Due to the high cost of EMMC, the after-sales cost will increase.

Embodiment 1

[0019] figure 1 The flow chart of the method for a kind of EMMC health degree judgment that the embodiment of the present invention provides, present embodiment can be applicable to the situation that needs to judge EMMC health degree, and this method can be carried out by the device of EMMC health degree judgment, this Devices may consist of software and / or hardware. The method provided in this embodiment specifically includes the following steps:

[0020] Step 110, acquire and save the stored value in the preset register bit in the EMMC.

[0021] Wherein, the preset memory bit may be a register bit in the EMMC to determine whether the storage block is valid. For example, the storage structure of EMMC is composed of a preset number of storage blocks. The ratio of the number of valid storage blocks to the total number of storage blocks or the number of invalid storage blocks and the storage block can be stored in the preset register bits. The proportion of the total number ...

Embodiment 2

[0031] figure 2 It is a flowchart of a method for judging the health degree of an EMMC provided by Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the foregoing embodiments. The method provided in this embodiment specifically includes the following steps:

[0032] Step 210, divide the corresponding health level for the storage value in the preset register bit in the EMMC and save the corresponding relationship between the storage value and the health level.

[0033] Preferably, the corresponding health level can be divided for the stored value according to the range of the stored value in the preset memory, and the corresponding relationship between the stored value and the health level can be saved, so that after the stored value is obtained, it can be determined and obtained. Corresponding health level. Among them, the higher the health level, the lower the damage of the EMMC. If the health level is high, the EMMC may not be re...

Embodiment 3

[0051] image 3 It is a flowchart of a method for judging the health degree of an EMMC provided by Embodiment 3 of the present invention. This embodiment is further optimized on the basis of the foregoing embodiments. The method provided in this embodiment specifically includes the following steps:

[0052] Step 310, divide the corresponding health level for the stored value in the preset register bit in the EMMC and save the corresponding relationship between the stored value and the health level.

[0053] Step 320, acquiring the stored value in the preset register bit in the EMMC and caching the stored value into the preset buffer.

[0054] Wherein, step 310 may be the same as step 210, and step 320 may be the same as step 220, which will not be repeated in this embodiment.

[0055] Step 330, saving the health level corresponding to the stored value in the preset buffer to a preset file.

[0056] Preferably, after the storage value is obtained from the preset buffer, acc...

Abstract

The embodiment of the invention discloses a method and a device for judging the health degree of an EMMC (Embedded Multi Media Card). The method comprises the following steps that: obtaining and storing a storage value in a preset register bit in the EMMC; and according to the storage value in the preset register bit, determining the health degree of the EMMC. By use of the method, a user can visually and conveniently determine the health degree of the EMMC so as to determine whether the EMMC needs to be replaced or not so as to avoid a situation that the EMMC which does not need to be changed is changed, after sale cost is lowered, meanwhile, operation is convenient and simple, and cost is low.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for determining the health of an EMMC. Background technique [0002] With the continuous development of smart terminals, the use of smart terminals is becoming more and more popular. Currently, most smart terminals use EMMC (Embedded Multi Media Card, embedded multimedia card). [0003] During the use of smart terminals, various suspected EMMC damages often occur. For example, if the mobile phone password cannot be verified, the after-sales maintenance personnel must first determine whether the password entered by the user cannot be stored in the EMMC due to EMMC damage. The password is verified, so that the password cannot be verified and the smart terminal cannot be used. However, in the prior art, since determining whether the EMMC is damaged requires additional testing equipment, and the testing equipment is expensive,...
