Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In one embodiment, as shown in fig. 1, a firmware recovery method is provided, where this embodiment is applied to a terminal to illustrate the method, and it is understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:
step 102, when an abnormal state is detected, a timer is started.
Terminals are a type of embedded computer system device, and software structures can be divided into system software and application software. In the software structure of the terminal, the system software mainly comprises an operating system and middleware, and a common terminal operating system comprises IOS, android, webOS, open source MeeGo, windows and the like. User terminals using different operating systems can acquire new versions of firmware packages from the server to perform firmware upgrading, for example, a user can use a smart phone to download the latest versions of firmware packages from the server to perform upgrading. The Firmware (Firmware) refers to a program written in an EROM (erasable read only memory) or an EEPROM (electrically erasable programmable read only memory). The firmware acts as the software for the bottommost operation of the system. In a hardware device, some hardware devices have no other software components than firmware, so the firmware determines the functions and performances of the hardware devices. Firmware is typically stored in an electrically erasable read-only memory EEPROM (Electrically Erasable Programmable ROM) or FLASH chip in the device, a program that can be upgraded by a user, typically by a specific refresh program. Generally, software that is the most Basic and bottom-level of a digital product can be called firmware, such as Basic Input/output System (BIOS) on a computer motherboard. Typically, the programs stored in these hardware are not directly readable or modifiable by the user. With the development of technology, it is urgent for users to modify firmware to adapt to the continuously updated hardware environment, so that the rewritable programmable erasable read-only memory EPROM (Erasable Programmable ROM) and flash chips appear, and these chips can be repeatedly written and brushed, so that the firmware can be modified and upgraded. The terminals in the present application may include various types such as mobile terminals and PC terminals (personal computer). In the application software of the terminal, a developer can create applications of different service functions around the service field component, and the applications can be independently developed, managed and updated, so that the deployment, management and service function delivery can be simpler. The embedded terminal product is common acquisition and data transmission equipment, and the product functions are realized by executing firmware stored in a memory chip. The firmware can be programmed into the chip and then the chip is fixed in the product, and the more common way is to fix the chip on the circuit board.
Because the firmware in the terminal product needs to be upgraded in the using process of the terminal product, the product is perfected. Firmware upgrade can be performed by burning firmware on a chip. For example IAP (In Application Programming) applies field programming techniques, which are widely used for firmware upgrades without requiring special equipment and chip removal, saving labor. IAP is In Application Programming's acronym, and IAP is that the User's own procedure burns the partial region of User Flash chip in the operation process, and the purpose is in order to be convenient to update the firmware program in the product through the communication port of reserving after the product is released. However, if the remote IAP technology fails in the process of upgrading the application field, or the upgrade file is wrong, the terminal cannot work normally. For example, when firmware is upgraded, a new version of firmware is not completely written into the chip, and power failure occurs, so that the product cannot work normally at this time, and the terminal cannot work normally. Specifically, in the firmware upgrading process, when the terminal detects an abnormal state, a timer is started to start timing. The abnormal state is a state that the firmware may be interfered by external factors in the upgrading process, so that the firmware is failed to be upgraded, and the terminal cannot work normally, namely the abnormal state. For example, the system is accidentally powered off in the upgrading process, so that the terminal cannot work normally.
And 104, when the timing reaches the preset duration, acquiring the identification information in the version number rule information corresponding to the firmware.
When the terminal detects an abnormal state, a timer is started. When the terminal detects that the timing reaches the preset duration, the terminal can acquire the identification information in the version number rule information corresponding to the firmware. The preset duration refers to a preset waiting duration in the system, for example, the preset duration may be set to 2 minutes. The version number rule information refers to preset version rules corresponding to different firmware. For example, the firmware version number rule information may be custom set to abcd.zzzz.hh.kk.nn.ss, where HH represents operater ID, i.e., the vendor identification or firmware identification, and KK represents the major version number. For example, when the operator ID value is 01, the firmware package corresponds to AT & T (AT & T is us operator), when the operator ID value is 09, the firmware package corresponds to DT (DT is japan operator), and when the operator ID value is 00, the firmware package corresponds to a general version. Specifically, when the terminal detects that the timing reaches the preset duration, the terminal may acquire the identification information in the version number rule information corresponding to the firmware from a default folder, or the terminal may also acquire the identification information in the version number rule information corresponding to the firmware from the NV value, where NV is short for NVRAM, and english name Nonvolatile Random Access Memory is a nonvolatile random access memory. Once the data is written into the NV value, the data is not lost even if power is lost, and the original setting can be still reserved after the next restart. Typically, NV is a proprietary file system that holds basic configuration and radio frequency parameters for the handset. When the mobile phone is turned off, the data stored in the NV cannot be lost. NV can thus be employed to save important parameters of the handset terminal.
And 106, recovering the firmware to the firmware version corresponding to the identification information according to the identification information.
After the terminal obtains the identification information in the version number rule information corresponding to the firmware, the terminal can restore the firmware to the firmware version corresponding to the identification information according to the identification information. The identification information refers to an operator identification or a firmware identification, for example, when the identification information corresponding to a certain firmware is 00, the identification firmware package corresponds to a general version. Specifically, when the terminal detection timer reaches the preset duration, the terminal may obtain the identification information in the version number rule information corresponding to the firmware from the NV value or the preset default folder, for example, when the terminal obtains that the identification information in the version number rule information corresponding to the firmware is 01, that is, the operator ID value is 01, the terminal restores the firmware to the firmware version corresponding to the identification information, that is, the firmware version corresponding to the firmware package is an AT & T package (AT & T is the american operator) according to the identification information 01. When the terminal obtains the identification information in the version number rule information corresponding to the firmware from the preset default folder as 09, namely, the operator ID value is 09, the terminal restores the firmware to the firmware version corresponding to the identification information according to the identification information 09, namely, the firmware version corresponding to the firmware package is a DT package (DT is a japan operator). The firmware package is a firmware of a certain operator, different operators can produce and manufacture different firmware, and each firmware carries corresponding firmware identification information.
In the traditional firmware recovery mode, when the firmware is recovered automatically, no matter which version the previously operated firmware is, the firmware is recovered to the general version finally, so that the process of converting the firmware is required to be carried out for different user terminals, the current correct firmware version used by the user can be switched, the accuracy of the firmware recovery is poor, and the targeted quick and convenient firmware recovery can not be provided for the user. In this embodiment, when the terminal detects the abnormal state, the terminal starts the timer to start counting. When the terminal detects that the timing reaches the preset duration, the terminal can acquire the identification information in the version number rule information corresponding to the firmware, and the terminal restores the firmware to the firmware version corresponding to the identification information according to the acquired identification information. Therefore, the firmware can be directly restored to the version used by the current user, the complicated conversion process is avoided, the processing time is effectively saved, the firmware restoration efficiency is improved, and the firmware restoration accuracy is effectively improved.
In one embodiment, before the abnormal state is detected, the method further includes a step of acquiring identification information corresponding to the currently running firmware, and specifically includes:
and acquiring the identification information corresponding to the currently running firmware.
The identification information is stored in a nonvolatile manner.
Before the terminal detects the abnormal state, i.e. the terminal is in a normal working state, or before the terminal is in firmware upgrading, the terminal can acquire the identification information corresponding to the currently operated firmware, i.e. the terminal acquires the firmware identification information corresponding to the normal working state, and the identification information corresponding to the currently operated firmware is stored in a nonvolatile manner. For example, after the terminal acquires the identification information corresponding to the currently running firmware, the terminal may write the acquired identification information into the NV value, and when the firmware is recovered, the terminal may directly read the identification information corresponding to the firmware in the NV value. Once the data is written into the NV value, the data is not lost even if power is lost, and the original setting can be still reserved after the next restart. Typically, NV is a proprietary file system that holds basic configuration and radio frequency parameters for the handset. When the mobile phone is turned off, the data stored in the NV cannot be lost. NV can thus be employed to save important parameters of the handset terminal. Therefore, even if unexpected situations such as unexpected power failure occur in the upgrading process, the terminal can acquire the firmware identification information matched with the user terminal from the nonvolatile memory after the terminal is started and when the firmware is required to be recovered, the firmware is recovered automatically, and the accuracy of the firmware recovery is improved effectively.
In one embodiment, as shown in fig. 2, the method further includes a step when changing the SIM card to cause the firmware package to be switched, specifically including:
step 202, when the SIM card is changed to cause the switching of the firmware package, the identification information corresponding to the switched firmware package is obtained.
Step 204, synchronously updating the identification information into a nonvolatile storage, wherein the nonvolatile storage is used for recording the changed identification information.
When the user changes the SIM card, namely when the terminal detects that the firmware package is switched caused by the operation of changing the SIM card, the terminal can acquire the identification information corresponding to the switched firmware package. Further, the terminal synchronously updates the acquired identification information into a nonvolatile memory, and the nonvolatile memory is used for recording the changed identification information. For example, when the terminal detects that the identification information corresponding to the currently running firmware is 01, and when the user changes the SIM card, that is, when the terminal detects that the firmware package is switched due to the operation of changing the SIM card, the terminal may acquire that the identification information corresponding to the switched firmware package is 09. Further, the terminal synchronously updates the acquired identification information 09 to the nonvolatile storage, and the nonvolatile storage is used for recording the changed identification information, that is, the terminal can synchronously update the identification information corresponding to the original firmware in the NV value to the identification information 09 corresponding to the switched firmware package when the identification information corresponding to the original firmware in the NV value is 01. In addition, a customized firmware version number rule may be preset, for example, the firmware version number rule information may be customized to abcd.zzz.hh.kk.nn.ss, where HH represents operater ID, i.e., a vendor identifier or a firmware identifier, and KK represents a major version number. The third byte in the version number rule information can be set to represent an operator ID, and an initial value of 00, i.e., an operator ID of 00 indicates that the firmware packet corresponds to a general version. When the user changes the SIM card operation to cause the switching of the firmware package, the terminal can synchronously update the firmware package identification information to the nonvolatile storage according to the dynamically changed firmware package identification information, and the nonvolatile storage is used for recording the changed identification information. Therefore, the firmware can be directly restored to the version used by the current user terminal, the complicated conversion process is avoided, the processing time is effectively saved, the firmware restoration efficiency is improved, and the firmware restoration accuracy is effectively improved.
In one embodiment, before the abnormal state is detected, the method further includes a step of acquiring identification information corresponding to the currently running firmware, and specifically includes:
and acquiring the identification information corresponding to the currently running firmware.
The identification information is stored in a built-in data folder.
Before the terminal detects the abnormal state, i.e. the terminal is in a normal working state, or before the terminal is in firmware upgrading, the terminal can acquire the identification information corresponding to the currently operated firmware, i.e. the terminal acquires the firmware identification information corresponding to the normal working state, and stores the identification information corresponding to the currently operated firmware into the built-in data folder. For example, after the terminal acquires the identification information corresponding to the currently running firmware, the terminal may store the acquired identification information in the built-in data folder, and when the firmware is recovered, the terminal may directly read the identification information corresponding to the firmware in the built-in data folder. Therefore, when the OACC state occurs due to unexpected power failure in the upgrading process, the terminal automatically executes the firmware recovery flow after the preset time length, and the firmware can be directly recovered to the firmware version matched with the current user terminal after the operator ID value corresponding to the current terminal equipment is acquired by firstly reading the data in the built-in data folder, so that the complicated conversion process is avoided, the processing time is effectively saved, the firmware recovery efficiency is improved, and the firmware recovery accuracy is also effectively improved.
In one embodiment, as shown in fig. 3, the method further includes a step when changing the SIM card to cause the firmware package to be switched, specifically including:
Step 302, when the SIM card is changed to cause the switching of the firmware package, the identification information corresponding to the switched firmware package is obtained.
Step 304, synchronously updating the identification information into a built-in data folder, wherein the built-in data folder is used for recording the changed identification information.
When the user changes the SIM card, namely when the terminal detects that the firmware package is switched caused by the operation of changing the SIM card, the terminal can acquire the identification information corresponding to the switched firmware package. The terminal synchronously updates the acquired identification information into a built-in data folder, wherein the built-in data folder is used for recording the changed identification information. For example, when the terminal detects that the identification information corresponding to the currently running firmware is 01, after the user changes the SIM card, that is, when the terminal detects that the firmware package is switched, the terminal may acquire the identification information corresponding to the switched firmware package, that is, the terminal acquires the identification information corresponding to the switched firmware package as 09. Further, the terminal synchronously updates the acquired identification information 09 to the built-in data folder, where the built-in data folder is used for recording the changed identification information, that is, the terminal can synchronously update the identification information corresponding to the original firmware in the built-in data folder to the identification information 09 corresponding to the switched firmware package with 01. Therefore, when the abnormal state occurs due to unexpected power failure in the upgrading process, the terminal automatically executes the firmware recovery flow after the preset time length, and the firmware can be directly recovered to the firmware version matched with the current user terminal after the updated operator ID value corresponding to the terminal equipment is 09 by firstly reading the data in the built-in data folder, namely, the terminal recovers the firmware to the DT (DT represents Japanese operator) firmware version corresponding to the identification information 09, so that the complicated conversion process is avoided, the processing time is effectively saved, the firmware recovery efficiency is improved, and the firmware recovery accuracy is also effectively improved.
In one embodiment, after power-on, when only OACC ports are detected, the system is indicated as entering an abnormal state.
In the process of upgrading the firmware, the firmware may be interfered by external factors, so that the firmware is failed to upgrade, and the terminal cannot normally work, for example, the system is accidentally powered off in the process of upgrading, so that the terminal cannot normally work. When the terminal detects that only OACC ports are needed after the system is powered off accidentally in the upgrading process and is restarted, the system is indicated to enter an abnormal state. For example, when the terminal encounters power-off or forced power-off in the upgrading process, after restarting, the user can open the device manager interface by triggering operation, and only OACC ports are left in the ports related to the system from the device manager interface, i.e. the terminal enters OACC state, which indicates that the system enters an abnormal state and firmware recovery is required. In the firmware upgrading process, various external factors may cause firmware upgrading failure, so that the terminal enters an abnormal state, therefore, when a user cannot judge whether the current terminal equipment is in the abnormal state or not and needs firmware recovery, the user can check whether only OACC ports exist through checking ports operated in the background in the equipment manager, if the user judges that the current terminal equipment has completed firmware upgrading and does not need firmware recovery, the user can cancel the firmware upgrading through triggering operation when the system timer does not reach the preset duration. Fig. 4 is a schematic flow chart of firmware recovery corresponding to a certain mobile terminal device. When the terminal detects that only OACC ports exist currently, namely the terminal enters OACC state, the terminal starts a timer to start timing, when the timing reaches a preset duration, the terminal triggers and activates a firmware recovery process, the terminal reads data from a preset built-in data folder, and identification information corresponding to firmware, namely an operator ID value is obtained. And the terminal restores the firmware to the firmware version corresponding to the operator ID value according to the acquired identifier information, namely the operator ID value. Therefore, a user can quickly and conveniently judge whether the terminal equipment needs firmware recovery according to the port parameters in the equipment manager, a few complicated processes are avoided, the firmware recovery efficiency is effectively improved, and convenience is brought to the user.
In one embodiment, when the terminal detects that only OACC ports are available after the system is powered off accidentally during the upgrade process and is restarted, the system is indicated to enter an abnormal state. For example, when the terminal encounters power-off or forced power-off in the upgrading process, after restarting, the user can open the device manager interface by triggering operation, and only OACC ports are left in the ports related to the system from the device manager interface, i.e. the terminal enters OACC state, which indicates that the system enters an abnormal state and firmware recovery is required. In the firmware upgrading process, various external factors may cause firmware upgrading failure, so that the terminal enters an abnormal state, therefore, when a user cannot judge whether the current terminal equipment is in the abnormal state or not and needs firmware recovery, the user can check whether only OACC ports exist through checking ports operated in the background in the equipment manager, if the user judges that the current terminal equipment has completed firmware upgrading and does not need firmware recovery, the user can cancel the firmware upgrading through triggering operation when the system timer does not reach the preset duration. When the terminal detects that only OACC ports exist currently, namely the terminal detects an abnormal state, the terminal starts a timer to start timing, when the timing reaches a preset duration, the terminal triggers and activates a firmware recovery process, the terminal reads data from a preset built-in data folder or NV value, and identification information corresponding to firmware, namely an operator ID value is obtained. And the terminal restores the firmware to the firmware version corresponding to the operator ID value according to the acquired identifier information, namely the operator ID value. Therefore, the firmware can be directly restored to the version used by the current user, the complicated conversion process is avoided, the processing time is effectively saved, the firmware restoration efficiency is improved, and the firmware restoration accuracy is effectively improved.
