Description

The present invention relates to the field of mobile terminals, and in particular to a method and apparatus for updating firmware of a mobile terminal. BACKGROUND OF THE INVENTION A mobile terminal (also referred to as a mobile communication terminal) refers to a portable mobile computer device, and broadly includes a mobile phone, a data card, a tablet computer, and the like. Firmware refers to the software that is the most basic and lowest-level work of a digital product. The firmware is generally stored in an EEPROM (Electrically Erasable Programmable Read-Only Memory) or FLASH (Flash) chip in a mobile terminal. In, it can be updated in some way. Since the firmware version is closely related to the hardware of the mobile terminal, the firmware of the early mobile terminal can generally only be provided by the mobile terminal manufacturer. With the development of smart mobile terminals and their operating systems, especially the development of the open source Android operating system, in addition to mobile terminal manufacturers, a large number of individuals or third-party companies have begun to develop and provide mobile terminal firmware. The firmware of mobile terminals is becoming more and more abundant, but the way of firmware update is mostly complicated, cumbersome or subject to many factors, thus hindering the copying and propagation of firmware. At present, the more common firmware update methods are as follows.

1. Update by PC side auxiliary tool. This method requires more preparation work. You need to find the right target firmware version, the appropriate upgrade tool, and the right driver. Moreover, the upgrade exception is also likely to damage the mobile terminal firmware, making the mobile terminal that failed the update completely unusable.

2. Updated via FOTA (Firmware Over The Air). The method only needs to connect the mobile terminal to the receiving network, and the mobile terminal can automatically download the differential upgrade package and automatically complete the upgrade process, which is convenient and fast, and has high reliability. However, this method is generally only applicable to the same manufacturer and the same series of versions. The differential upgrade package can only be provided by the mobile terminal manufacturer. Therefore, the FOTA upgrade can only be upgraded to the official firmware version, the selectivity is small, and the firmware changes are limited in a single upgrade.

3. Update the package update via SD (Secure Digital) card. This method needs to obtain the SD card update package (usually also needs to be searched and downloaded through the network), and then copy it to the SD card; then start the update process through the menu of the mobile terminal interface. The whole update process is relatively fast, relatively safe and reliable, but the source of the update package is often only the mobile terminal manufacturer, and the range of options is small. In summary, all three methods need to find and obtain the target firmware version to be upgraded, and some need help tools to perform firmware update. In addition, these three types of solutions can only see the effect of the target firmware after the update is completed.

The method and device for updating the firmware of the mobile terminal of the present invention will be described in detail below with reference to specific embodiments. The existing firmware update method must rely on the network and computer platform. It needs to find the appropriate target firmware before updating, and the target firmware effect cannot be predicted before the update. In view of this situation, the present invention provides a mobile terminal firmware update method and apparatus, which can copy firmware in one mobile terminal to another mobile terminal, which simplifies the process of finding the target firmware and finds a suitable mobile. The terminal finds the target firmware, does not need external environment support such as network, does not need to use the personal computer platform, and does not need to copy and dump. In addition, the method does not need other auxiliary software and auxiliary equipment, and the operation is simple and quick. Moreover, the effect of the target firmware can be known in advance by the first mobile terminal providing the target firmware before the firmware update. The technical solution of the present invention includes a first mobile terminal that provides target firmware and a second mobile terminal that receives target firmware. The first mobile terminal includes a data communication module, a firmware extraction module, a hardware information acquisition module, a compatibility detection module, and a mode switching module. The second mobile terminal includes a data communication module, a firmware receiving module, a firmware update module, and hardware information. Detection module and mode switching module. The first mobile terminal is responsible for providing the target firmware, controlling the second mobile terminal, establishing a data channel, and transmitting the built-in target firmware to the second mobile terminal through the data channel. The second mobile terminal is responsible for assisting the first mobile terminal to establish a data channel, receiving the target firmware sent by the first mobile terminal, and replacing the original built-in firmware with the received target firmware. The data channel is a bridge connecting the first mobile terminal and the second mobile terminal, and is responsible for transmitting data between the first mobile terminal and the second mobile terminal. The data includes, but is not limited to: instruction data sent by the first mobile terminal to the second mobile terminal, command response information fed back by the second mobile terminal to the first mobile terminal, target firmware data embedded in the first mobile terminal, and second Hardware information of the mobile terminal, etc. In addition, each module of the first mobile terminal and the second mobile terminal may coexist in the same mobile terminal. Thus, each mobile terminal can serve as both the first mobile terminal and the second mobile terminal. Specifically, as shown in FIG. 5, the mobile terminal firmware update method of the present invention includes the following step aal-step aal0. Step a1: The data communication modules of the first mobile terminal and the second mobile terminal cooperate to establish a second data channel. Data channel types include, but are not limited to, USB cable, WIFI, Bluetooth, and the like. Preferably, the first mobile terminal and the second mobile terminal can be connected by a USB cable. Using the OTG (On The Go) technology, the second mobile terminal is used as the USB peripheral device of the first mobile terminal, and a USB data transmission path is established between the first mobile terminal and the second mobile terminal. In addition, the step may attach a protection mechanism such as identity authentication between the first mobile terminal and the second mobile terminal, so as to initially confirm that both parties are the same-group mobile terminal supporting firmware replication. Step a2: The first mobile terminal detects whether the own target firmware is compatible with the hardware of the second mobile terminal. The hardware information acquisition module in the first mobile terminal acquires the hardware configuration information of the second mobile terminal by using the hardware information detection module in the second mobile terminal, and further determines whether the hardware of the second mobile terminal can run the target built in the first mobile terminal. firmware. Preferably, the compatibility detecting module in the first mobile terminal queries whether the model of the hardware acquired from the second mobile terminal is in the supported hardware model list according to the pre-stored hardware model list supported by the target firmware. If all hardware of the second mobile terminal is supported, it indicates that the target firmware can run on the second mobile terminal, that is, the target firmware of the first mobile terminal is compatible with the hardware of the second mobile terminal; otherwise, it indicates that the two are incompatible. Step a3: The first mobile terminal sends a mode switching instruction to the second mobile terminal by using the second data channel, and the mode switching module of the second mobile terminal switches itself to the controlled upgrade mode after receiving the mode switching instruction, and the switching result is obtained. Report to the first mobile terminal. In order to update the mobile terminal firmware, the partition in which the mobile terminal firmware is located must be written without the mobile terminal firmware being used. Therefore, there is a need for an alternate thin system for mobile terminal firmware updates, hereinafter referred to as a firmware update system. The system comprises the foregoing four modules of a data communication module, a firmware receiving module, a firmware update module and a mode switching module located on the second mobile terminal. Under the firmware update system, the firmware update module has full write permission to the storage device partition where the firmware of the mobile terminal is working normally, and can update the entire contents of the partition where the mobile terminal firmware is located. The flow of the second mobile terminal switching to the controlled upgrade mode is as shown in FIG. 6. When receiving the mode switching instruction, the second mobile terminal sets an identifier to enter the "controlled upgrade mode" (an empty file /flags/enter_upgrade_firmware_mode.flg of the firmware file name stored in the pre-agreed path). Then, the mode switching module passes It is known that the second mobile terminal is restarted. During the restart of the second mobile terminal, the mode switching module checks whether the aforementioned identifier exists, and if so, enters the firmware update system; otherwise, starts the mobile terminal normal working system. After successfully cutting into the controlled upgrade mode, the second mobile terminal reports the information about the successful mode switching to the first mobile terminal, and sends a request for establishing the data channel to the first mobile terminal. Step a4: After receiving the feedback that the second mobile terminal mode is successfully switched, the first mobile terminal switches itself to the firmware extraction and transmission mode by the mode switching module. In order to extract the firmware of the mobile terminal, it is necessary to read the storage partition where the mobile terminal firmware is located without running the working terminal of the mobile terminal. Therefore, a specialized, streamlined system for firmware extraction and transmission is required, hereinafter referred to as the firmware extraction and delivery system. The firmware extraction and delivery system is a streamlined system that provides only the essential functions of data communication, firmware extraction, firmware delivery, and mode switching. Specifically, the foregoing includes a data communication module, a firmware extraction module, and a mode switching module, which are located on the first mobile terminal. The firmware extraction and delivery system is another backup system that is completely separate from the operating system when the mobile terminal is in normal use. The two systems are stored separately in two separate partitions. Both systems can be started independently, but not simultaneously. The application in the firmware extraction and transmission system has read data permission for the partition where the mobile terminal firmware is located. The process of the first mobile terminal switching from the normal working mode to the firmware extracting and transmitting mode is as shown in FIG. First, when the first mobile terminal receives the mode switching instruction, the mode switching module sets the identifier of the "firmware extraction and transmission mode" (an empty file /flags/enter_get_firmware_mode stored in the pre-agreed path of the firmware file name). Flg ) ₀ Then, the mode switching module notifies the first mobile terminal to restart. Finally, during the restart of the first mobile terminal, the mode switching module detects whether the foregoing identifier exists, and if so, enters the firmware extraction and transmission system; otherwise, starts the mobile terminal normal working system. Step a5: The first mobile terminal in the firmware extraction and transmission mode and the second mobile terminal in the controlled upgrade mode re-establish the data channel through the respective data communication module, that is, the first data channel. After the two steps a3 and a4 are completed, the first mobile terminal and the second mobile terminal respectively cut into the new mode will re-establish a connection through the USB device, the first mobile terminal is still a USB host device, and the second mobile terminal is still a USB slave device. device. Step a6: The first mobile terminal extracts its own built-in target firmware through the firmware extraction module, and sends it to the second mobile terminal. As mentioned earlier, there are multiple storage partitions on the storage device of the first mobile terminal. The firmware extraction module holds a partition information file that describes each partition information in the storage device. The file is written during the production process of the mobile terminal, and is updated by the upgrade tool when the partition information of the storage device changes. This file is stored in the root directory of the partition where the firmware extraction and sending system is located. The fixed name is: partiti _0n _t _a bl _e .inf. The firmware extraction module determines information such as a partition where the target firmware is located, a target firmware size, a start and end position, and the like according to the partition information file. And according to the information, the corresponding data is read from the storage device and sent to the second mobile terminal. Step a7: The first mobile terminal notifies the second mobile terminal to perform firmware upgrade after the target firmware is sent. Step a8: The firmware update module of the second mobile terminal updates its own firmware according to the received target firmware, and notifies the first mobile terminal after the update is completed. The firmware update module also holds a partition information file of the second mobile terminal, and after receiving the target firmware, writes the received target firmware to the corresponding partition corresponding to the mobile terminal firmware according to the partition information of the second mobile terminal. In the middle, the firmware update of the second mobile terminal is completed. At this time, the second mobile terminal has the target firmware (ie, the firmware to be updated) that is completely complete with the first mobile terminal, that is, the second mobile terminal clones the firmware of the first mobile terminal. The second mobile terminal sends an update completion instruction to notify the first mobile terminal that the firmware update is completed. Step a9: After the first mobile terminal receives the update completion instruction of the second mobile terminal, the sending mode switching instruction notifies the second mobile terminal to switch back to the normal working mode. Step a10: The first mobile terminal switches from the firmware extraction and transmission mode back to the normal working mode. At this point, the target firmware of the first mobile terminal is successfully cloned into the second mobile terminal, and the first mobile terminal and the second mobile terminal are all in the normal working mode, and the entire mobile terminal firmware update process ends. By adopting the technical solution of the invention, the purpose of updating the firmware of the mobile terminal quickly and conveniently is achieved, and the convenience of the firmware update process of the mobile terminal is improved. Compared with a mobile terminal that only supports the traditional firmware update mode, the firmware can be effectively accelerated in the user circle of the mobile terminal supporting the technical solution of the present invention, thereby promoting the development and growth of the user group of the mobile terminal. At the same time, enhance the brand loyalty and product recognition of such mobile terminal manufacturers. Many of the functional components described in this specification are referred to as modules to more particularly emphasize the independence of their implementation.

For example, an identified executable code module can comprise one or more physical or logical blocks of computer instructions, which can be constructed, for example, as an object, procedure, or function. Nonetheless, the executable code of the identified modules need not be physically located together, but may include different instructions stored in different physicalities. When these instructions are logically combined, they form a module and implement the specified purpose of the module. . In fact, the executable code module can be a single instruction or a number of instructions, and can even be distributed across multiple different code segments, distributed among different programs, and distributed across multiple memory devices. Likewise, operational data may be identified within the module and may be implemented in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed at different locations (including on different storage devices), and may at least partially exist as an electronic signal on a system or network. When the module can be implemented by software, considering the level of the existing hardware process, the module can be implemented in software. Without considering the cost, a person skilled in the art can construct a corresponding hardware circuit to implement the corresponding function. The hardware circuitry includes conventional Very Large Scale Integration (VLSI) circuits or gate arrays as well as existing semiconductors such as logic chips, transistors, or other discrete components. Modules can also be implemented with programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices, and the like. In the method embodiments of the present invention, the sequence numbers of the steps are not used to limit the sequence of the steps. For those skilled in the art, the steps of the steps are changed without any creative work. It is also within the scope of the invention. The above is a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
