Embodiment Construction

[0044] As mentioned in the background technology, since the user formatted the SD card as an encrypted built-in storage, the normal mount operation cannot be performed in the recovery mode at this time, resulting in the inability to obtain the OTA upgrade package on the built-in SD card in the recovery mode, and a smart The problem that the OTA in the device cannot be upgraded.

[0045] In view of the above problems in the prior art, the present application proposes an OTA upgrade package upgrade method. The method generates a mapping file from the upgrade package, and writes the mapping file into the Cache high-speed memory, so as to solve the problem in the prior art that the upgrade package is downloaded to a built-in encrypted SD card and the OTA upgrade fails, thereby improving user experience.

[0046] Such as figure 1 As shown, it is a schematic flow diagram of an OTA upgrade package upgrade method proposed in the embodiment of the present invention, including the foll...

Abstract

The invention discloses an OTA upgrade package upgrade method and equipment, which are applied to an intelligent system to read the encrypted upgrade package from a designated storage path for storing the encrypted upgrade package; decrypt the encrypted upgrade package, and obtain The upgrade package is written into the address space under the specified storage path, and the mapping relationship file is generated with the address space and the identifier used to index the address space; when the specified storage path and the mapping relationship file When the storage paths are different, the upgrade package obtained after decryption is read according to the mapping relationship file, and the upgrade is started after reading the upgrade package. When the intelligent system is OTA upgraded, the present invention can obtain the upgrade package information according to the mapping file generated by the upgrade package, thereby solving the problem that the upgrade package is downloaded to the built-in encrypted SD card and the OTA upgrade fails.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an OTA upgrade package upgrade method. The invention also relates to an intelligent device. Background technique [0002] In the current smart terminal, starting from Android 6.0, the smart system supports (accepts) the SD card in the adopt mode. The adopt mode is to format the SD card and set it as the built-in storage of the Android system, which can expand the system to a certain extent. The internal storage space, and the upgrade package will be encrypted before being stored in the SD card in the built-in storage state, so that the system cannot directly identify the encrypted upgrade package from the SD card, which can improve the privacy of the upgrade package. [0003] After downloading the upgrade package to the SD card using OTA technology, you need to restart the Android system to enter the recovery mode. In this mode, load the upgrade package data into the runni...
