Background
UFS (Universal Flash Storage, universal flash memory storage) is a memory device of a cell phone on which all system data and user data are stored, including operating systems, application software, user generated data such as photographs and videos taken, etc. The internal hardware of the UFS device is composed of a storage medium and a controller, and corresponding control software, called firmware. Due to the complexity of the firmware, the firmware of the manufacturer is still continuously upgraded and perfected after the UFS device leaves the factory. The UFS protocol specifies FFU (Filed Firmware Update) functionality that updates the firmware of the UFS while retaining the UFS data, so that the firmware can be updated after the UFS leaves the factory.
As the UFS is the only storage device in the mobile phone, once the data in the UFS is abnormal due to firmware updating, the mobile phone can not be started completely, and personal data of a user can be lost. Therefore, at present, each handset manufacturer completes verification of the UFS firmware in the development stage, and once sold, the firmware is not upgraded. But would be a significant penalty if the UFS firmware had serious defects not found.
The current upgrading method of firmware provided by the UFS manufacturer mainly comprises 2 kinds, namely, a special upgrading tool is used for directly upgrading the UFS device, and the upgrading method is adopted by the UFS manufacturer for upgrading the UFS device without a patch. Another is to provide simple tool software to upgrade UFS devices already produced by the patch in the laboratory.
The existing firmware upgrading mode is only aimed at unsold UFS devices, after-sales users cannot upgrade the firmware of the UFS devices, and a protection mechanism in the existing firmware upgrading process is not sound enough, so that the use is not safe enough, a certain failure probability exists, and the mobile phone is easy to restart continuously after failure.

The following describes in detail the scheme provided by the embodiment of the present application with reference to the accompanying drawings.
In the prior art, a UFS memory is commonly used in terminals such as mobile phones, firmware of the UFS memory is not upgraded after a chip leaves a factory, and the currently commonly used UFS firmware upgrading method has a certain failure probability, and is repeatedly upgraded and restarted after failure.
In order to at least partially solve the problems in the prior art and improve the security of the memory firmware upgrading process, an embodiment of the present disclosure provides a method for upgrading the memory firmware of a terminal.
As shown in fig. 1, fig. 1 is a flowchart of a memory firmware upgrade method of a terminal according to an embodiment of the present disclosure, including the steps of:
s11: acquiring target information of a memory;
specifically, the memory in the embodiment of the present disclosure is a memory of a terminal, and the terminal may be, for example, a mobile phone, a tablet, etc., the terminal may be a terminal of an android system, and the memory may be a UFS memory. The target information includes: firmware information of the memory. In some embodiments, the target information may also include device information for the memory, such as the model number and manufacturer of the memory, etc. In some embodiments, the firmware information includes a current firmware version of the memory.
S12: and determining whether the firmware of the memory needs to be upgraded according to the target information of the memory.
In some embodiments, the memory firmware may be determined to need to be upgraded by comparing the current firmware version of the memory with the version of the firmware to be upgraded, if the current firmware version is lower than the version of the firmware to be upgraded.
S13: if the memory firmware needs to be updated, judging whether a preset identifier exists.
In some embodiments, the preset identifier may be a file, that is, the target information may be recorded in the file, or the target information may be recorded directly by using a file name, for example, the target information is directly used as the file name of the file, so that only whether the file with the name of the target information is detected is needed, so that the search speed can be greatly improved, and whether the identifier exists can be quickly determined. In some embodiments, determining whether the preset identifier exists includes determining whether the preset identifier of the current firmware information including the memory exists, that is, determining whether the identifier exists first, and then determining whether the identifier of the current firmware information including the memory exists.
S14: if the preset identifier exists, the firmware of the memory is not upgraded.
In some embodiments, the preset identifier is used for recording whether the current firmware of the memory is updated with firmware and the firmware is updated with the firmware fails, that is, firmware information with the update failure is recorded in the preset identifier, so that when the firmware is updated, if the firmware information in the identifier is the same as the firmware information of the memory, the identifier is the preset identifier, which indicates that the current firmware of the memory is updated with the firmware but fails, so that the current firmware is not updated again, and repeated restarting caused by repeated updating after the firmware updating fails is avoided.
S15: if the preset identifier does not exist, the preset identifier is created according to the target information of the memory, and the memory firmware is updated.
Specifically, in some embodiments, if there is no preset identifier indicating that firmware upgrade has not been performed on the memory, the firmware upgrade may be performed, before the firmware upgrade, the preset identifier is created and the current firmware information is recorded by the preset identifier, which indicates that the current firmware is upgraded, and then the firmware upgrade is performed, so if the firmware upgrade is successfully performed from firmware 1 to firmware 2, the firmware information of firmware 1 is recorded in the preset identifier, and when the firmware upgrade is performed next time, the firmware upgrade is desired to be performed from firmware 2 to firmware 3, the firmware upgrade may be performed normally although the firmware upgrade is performed although the firmware information of firmware 1 is recorded in the identifier before the upgrade is performed, and if the firmware upgrade is failed, the firmware upgrade from firmware 1 to firmware 2 is not attempted again because the firmware information of firmware 1 is already recorded in the preset identifier.
In some embodiments, the firmware upgrade program of the memory and the firmware to be upgraded are integrated in the operating system of the terminal. In the prior art, after the memory leaves the factory, the memory cannot be upgraded, and in the embodiment of the disclosure, the firmware to be upgraded and the firmware to be upgraded are integrated in the operating system of the terminal, so that the terminal can directly upgrade the firmware of the memory without using a professional upgrade tool, and the operation of a user is facilitated.
In some embodiments of the present disclosure, when a terminal is started, target information of a memory is obtained, and whether the firmware of the memory needs to be upgraded is determined according to the target information of the memory. Specifically, before the firmware of the memory is upgraded, whether the firmware is upgraded is judged, when the opportunity of judging whether the firmware is upgraded is that the memory is started, the desktop is not accessed, and the application program is prevented from accessing the memory when the firmware is upgraded, so that the judgment is performed when the terminal is started, and if the firmware is required to be upgraded, the desktop is not accessed, so that the application program is prevented from accessing the memory.
In some embodiments, determining whether an upgrade to the memory firmware is required based on target information of the memory includes: acquiring white list information and a version of firmware to be upgraded; if the version of the firmware to be upgraded and the target information of the memory meet the requirements of the white list information, the firmware of the memory needs to be upgraded; wherein the whitelist information includes: before and after firmware versions allowing upgrading, or device information allowing upgrading and before and after firmware versions allowing upgrading; the target information of the memory includes: firmware information of the memory, or firmware information of the memory and device information of the memory; the firmware information of the memory includes: the current firmware version of the memory.
Specifically, in some embodiments, the white list records which memories can be upgraded with firmware, and to which versions the firmware can be upgraded from, if the target information of the memory required to be upgraded with firmware accords with the condition recorded in the white list information that the firmware is allowed to be upgraded, the firmware can be upgraded, and if the device information of the memory does not accord with the condition recorded in the white list information that the firmware is allowed to be upgraded, the firmware is not upgraded, so that the condition that the firmware is not upgraded due to incompatibility is prevented.
In some embodiments, the memory firmware is upgraded in Recovery mode. Specifically, the Recovery mode is a reduced mode of the Android system, only the kernel and a small number of service programs of the operating system are loaded in the mode, the complete Android system in the normal mode is not loaded, and the mode mainly performs some work related to system maintenance. The reason for doing so is to ensure that the memory is hung into the read-write command of the memory in the upgrading process to prevent the firmware upgrading from being interfered, and the firmware upgrading is abnormal, because a plurality of read-write operations are carried out on the memory in the starting process of the normal mode, and the Recovery mode has no read-write operation on the memory after the starting, thereby ensuring the safety of the memory firmware upgrading and effectively reducing the probability of upgrading failure.
In some embodiments, upgrading the memory firmware includes: generating a firmware upgrading instruction, and controlling the terminal to enter a first mode; and reading the firmware upgrading instruction and upgrading the memory firmware in the first mode. In some embodiments, the first mode is a Recovery mode, a firmware upgrade instruction is generated after firmware upgrade is determined, and firmware upgrade is performed after the firmware upgrade instruction is detected after the firmware upgrade is restarted to enter the Recovery mode.
In some embodiments, upgrading memory firmware in a first mode includes: the method comprises the steps of obtaining firmware to be upgraded, reading the firmware to be upgraded into a user space of a memory, copying the firmware to be upgraded from the user space to a kernel space, writing the firmware to be upgraded into a memory, and upgrading the memory firmware.
Specifically, in some embodiments, the firmware to be upgraded may be pre-stored in a memory of the terminal, and the firmware of the memory needs to be refreshed when the firmware is upgraded, so that the firmware to be upgraded needs to be put into the memory first, the memory includes a user space and a kernel space, an application program usually runs in the user space, an operating system and a driver program run in the kernel space, the user space has different rights from the kernel space, the kernel space has rights of all hardware devices, the user space has only rights of common hardware, and higher rights are needed when the firmware is upgraded to the memory, so that the firmware is required to run in the kernel space.
In some embodiments, obtaining firmware to be upgraded, and reading the firmware to be upgraded into a user space of a memory includes: reading target information of the memory; determining the storage position of firmware to be upgraded from a white list according to the target information of the memory; and reading the firmware to be upgraded into a user space of the memory according to the storage position. Specifically, in some embodiments, after entering the first mode, target information of the memory is read first, and according to the target information, a corresponding storage location of the firmware to be upgraded is searched in the white list, in some embodiments, a plurality of firmware programs may be provided in the terminal, but the firmware programs that can be used for upgrading of the memory need to meet the requirement of the white list, so that the firmware programs that can be upgraded, namely the firmware to be upgraded, are searched from the white list first, the storage location of the firmware to be upgraded is recorded in the white list, and the firmware to be upgraded is read into the memory according to the storage location.
In some embodiments, before the firmware is upgraded, the firmware to be upgraded is obtained, and the manner of obtaining the firmware to be upgraded includes: and acquiring a system upgrade package in an Over The Air (OTA) mode, wherein The firmware to be upgraded is integrated in The system upgrade package. In some embodiments, the terminal is restarted after the firmware of the memory is upgraded.
In order to better illustrate the methods set forth by the embodiments of the present disclosure, a specific embodiment is set forth below. Referring to fig. 2 and 3, the memory is illustrated as UFS memory in the present embodiment, and the terminal is illustrated as a mobile phone, but this illustration is only illustrative and not limiting.
In this embodiment, the UFS firmware upgrading program and the target UFS firmware to be upgraded are integrated in a formal user system software version, and after the normal mode of the mobile phone is started, the information of the current UFS device of the mobile phone, including the manufacturer name, the device name and the firmware version number information, is read. A whitelist of firmware upgrades may be built into the system, only the firmware versions in the whitelist are upgraded. The white list contains manufacturer information, device information and firmware version information of all UFS devices supporting firmware upgrade. The firmware version information contains the information of new and old firmware versions before and after upgrading, namely, upgrading from a certain old version to a certain new version is allowed.
Judging whether the current UFS device needs to be upgraded with firmware, if not, doing no operation, continuing normal starting, otherwise, continuing to next step, judging whether a UFS upgrading identification file recorded with the current firmware version number and the UFS device number exists, and if the identification file exists, indicating that the upgrading has been performed once, but the upgrading is not successful, not performing the upgrading, and continuing normal starting. The presence of this identification document proves that this firmware version has been upgraded once. Even if the firmware upgrade fails due to some abnormal condition, the firmware version number of the UFS is still the old version number before the upgrade, if this flag file is not present, the upgrade operation is entered again, and this may occur as a dead loop.
With continued reference to fig. 2, if the UFS upgrade identification file with the current firmware version number and the device number is not recorded, a character string is formed with the UFS device number and the firmware version number as a file name, and the UFS upgrade identification file is created.
And setting a UFS upgrading command, and restarting to enter a Recovery mode.
Referring to fig. 3, entering a Recovery mode, detecting a UFS firmware upgrade command, performing a firmware upgrade operation of the UFS, clearing a Recovery flag after the UFS firmware upgrade is completed, and restarting to enter a normal mode.
For the process of firmware upgrade in Recovery mode, please refer to fig. 4, read the device information of UFS, including manufacturer information, device information (such as model) and current firmware version, obtain the corresponding location of the firmware file to be upgraded stored from the white list, and read the content of the target file into the memory, specifically in the user space of the memory.
The firmware to be upgraded is transferred from the user space to the kernel space, for example, the following manner can be adopted: opening a device file of the UFS, sending an ioctl command to a device handle, wherein the specific command word is SG_IO, and the transferred parameters comprise a command word for upgrading the UFS firmware and an address of the UFS firmware in a memory, so that the command for upgrading the UFS firmware and related information are transferred from a user space to a kernel space.
The firmware to be upgraded is then written to the UFS device, for example: in the process of ioctl, the kernel space receives the SG_IO command word and parameters, writes the command word and the firmware content of the UFS firmware upgrade into the UFS, and completes the operation of the firmware upgrade of the UFS.
After the firmware is upgraded, restarting to enter a normal starting mode, wherein the UFS device is new in firmware, and the whole upgrading process is completed.
And after the normal mode is re-entered in the restarting process, the firmware version number of the UFS device is read again, and if the upgrade is successful, the new firmware version number after the upgrade is read for the time, and the normal starting is continued. If the upgrade fails, the old firmware version number before the upgrade is read, and then whether the upgrade identification file exists is judged, and the upgrade flow is stopped and normal starting is continued because the upgrade identification file exists, so that the infinite restarting cycle caused by the upgrade failure of the memory firmware is avoided.
The present disclosure also proposes a memory firmware upgrade apparatus of a terminal, as shown in fig. 5, including:
an acquisition unit 10 for acquiring target information of the memory, the target information including: firmware information of the memory;
