Description
Technical Field
The invention relates to an android firmware application device and an android firmware upgrading method.
Background
An operating system of some kind, plus the necessary hardware (e.g., processors, memory, etc.) needed to run the operating system, may be considered an example system in which various applications (an application refers to software or programs that can run in the operating system of the example system) can run. The cloud system can be formed by centrally managing a plurality of example systems according to a certain architectural mode (such as distributed mode). Generally, the cloud system is in charge of daily operation by an operator to provide services for users.
In recent years, the open source Android (Android) system has been widely used and is often selected as the operating system of the instance system. Generally, an operator of the cloud system is responsible for software development and does not have hardware production capacity. The operator provides firmware (firmware) to the factory with hardware production capability, and the factory burns the firmware into the memory of the example system, so that the example system can work normally. For an operator, the process has a risk of disclosure, and the technical secret of the operator can be obtained by cracking the firmware by others.
Furthermore, the amount of code for the android system is large, which may exceed 1G if the firmware includes all partitions of the android system. The larger the firmware, the longer the time to burn in the memory, and the factory typically charges the operator a fee in terms of the burn-in time. Operators often subscribe to a large number of example systems, and the excessive android firmware can significantly increase the cost of the operators. If the code of the android system is updated frequently by the operator, new firmware is compiled when a new instance system is ordered, further increasing the cost.
The disclosure in the "background" section of the specification is helpful to those skilled in the art to understand the technical solution of the present invention, but should not be construed as necessarily belonging to the prior art or common general knowledge.

Detailed Description
The following describes embodiments of the present invention in further detail. It should be noted, however, that the scope of the present invention is not limited by the specific disclosure described. Any technical solution obtained by performing the same or equivalent replacement on technical elements in the described specific technical solution or technical solution obtained by a person skilled in the art without creative work on the basis of the described specific technical solution should be considered to fall within the protection scope of the present invention.
The android instance system is implemented in a simpler way by utilizing an existing development board (such as an ARM development board). Conventional android firmware for development boards includes u-boot, resource, misc, kernel, system, recovery, sysbackup partitions, where the partition names boot, misc, system, recovery, etc. exist in almost all android systems solutions. The boot partition is a common boot partition, and the android system is dependent on the boot partition when normally starting up to enter a normal mode. In some technical solutions of the android system, the boot partition includes a kernel of the android system, but in the technical solution of the present invention, the kernel of the android system is stored in the kernel partition, and the boot partition does not include the kernel of the android system. The misc partition is a miscellaneous partition and stores configuration files of some system settings or other partitions, such as boot information of a recovery partition. The system partition is a common system partition that stores the entire android system (except for the kernels that have been stored in other partitions, etc.). The recovery partition stores files required when the android system enters a recovery (recovery) mode. The u-boot partition is a universal boot loader (universal boot loader). The resource partition stores parameters corresponding to the development board, for example, what operation the kernel of the android system performs according to different level signals of the development board. The kernel partition stores the kernel of the android system. The sysbackup partition is a system backup partition, in some technical solutions, the android system is provided with more than two system backup partitions, the firmware only includes one system backup partition, the partition is a read-only partition, and a number 1(sysbackup1) is added behind the name of the partition.
The android firmware provided by the technical scheme of the invention only comprises u-boot, misc, recovery partition files and files (parameter files) for identifying the partition table information. The recovery partition file is composed of a virtual memory disk (ramdisk) started by a boot, a resource and kernel partition file (i.e. complete files in the resource and kernel partitions), and a small amount of user mode (user mode) applications.
The application of recovery partition files comprises an application with a special function (hereinafter referred to as an R application), wherein the R application can run in a recovery mode of an android system, and enters different working modes according to different Input levels (which can be single levels or level combinations) of a bus extender (General Purpose Input Output, GPIO), the working modes comprise a test mode and an initialization mode, the test mode can detect hardware of an example system, and the initialization mode can download a complete partition file of the android system from a storage server of a cloud system.
When the android firmware provided by the technical scheme of the invention is started (the android firmware can be regarded as an incomplete android system and can also be started due to the u-boot partition), the file of the u-boot partition is loaded and executed firstly, the u-boot partition finds that the boot partition is not verified, the android system cannot be normally started to enter a conventional mode, and the u-boot partition loads the file of the recovery partition to enter a recovery mode. The files of the recovery partition comprise kernel files of an android system, the android kernel can run in a recovery mode, and the R application can correspondingly run in the android kernel.
When the example system is located in a factory, a debugging board externally connected with the example system development board can enable the R application to enter a test mode by inputting the GPIO level. In the test mode, the R application can detect whether hardware such as a processor, a memory and the like of the example system works normally according to the instruction of the debugging board.
After the operator obtains the example system from the factory, the cloud system is built by using the example system. Different types of controllers are arranged in the cloud system to manage the example system. The controller comprises an ARM controller, namely a Linux server (armcontroller) with an ARM architecture, the controller is low in cost, a hardware circuit of the controller is connected with a development board of the example system, and the android system in the example system is managed through the input GPIO level. Operators often set storage servers in the cloud system, the storage servers store files related to technical secrets of the operators, and the operators take strict physical isolation and technical protection measures on the storage servers. Each instance system in the cloud system can communicate with the storage server, and the storage server transmits the required files to the instance system after verifying that the identity of the instance system is correct.
After the example system is added into the cloud system, the ARM controller enables the R application to enter an initialization mode through the GPIO level, and the R application can download a complete partition file of the android system from the storage server.
By utilizing the android firmware and the R application, the android firmware upgrading method can be realized. The flow of the android firmware upgrading method is shown in fig. 1, and includes:
s101: the controller controls the android firmware application to enter an initialization mode.
Specifically, the ARM controller inputs a preset GPIO level to enable the R application to enter an initialization mode.
S102: and the android firmware application is connected with the storage server according to the address written in advance, and the complete partition file of the android system is downloaded from the storage server.
Specifically, an address of a storage server is written in the R application in advance, after the R application enters an initialization mode, the R application is connected to the storage server according to the address, the latest version of the android system complete partition file is downloaded from the storage server, and the files are stored in a memory of the instance system.
S103: the android firmware application restarts into the normal mode of the android system.
Specifically, after all android system partition files are stored locally, the R application restarts the android system, and the android system enters a conventional mode to run after file deletion does not exist after the android system is restarted.
The conventional android firmware may exceed 1G, while the android firmware provided by the technical scheme of the invention is only about 30M. The 1G data is programmed for at least 5 minutes according to the current programming technology, while the 30M data is programmed for only 10 seconds. The android firmware provided by the technical scheme of the invention has a single function, only contains partition files essential for factory test case system hardware, does not contain core codes of the android system, does not need to be updated or upgraded except extreme conditions such as repartitioning of a partition table, and can be used by an operator for a long time. Meanwhile, codes related to technical confidentiality of the operator do not need to be sent out, and the risk of secret leakage of the operator is greatly reduced.
On the basis of the specific technical solutions described above, those skilled in the art can completely construct other solutions, which are not listed here.
