Description
Technical Field
The present disclosure relates to the field of computer technologies, and in particular, to a method and an apparatus for determining a working mode, and a method and an apparatus for controlling the working mode.
Background
Some electronic devices (such as mobile phones and the like) connect a pull-up resistor or a pull-down resistor to a certain Pin of a main chip, and after the electronic devices are powered on, the electronic devices can determine to execute a preset action according to the signal level state of the Pin, and the Pin of the chip playing the role is called Strap Pin. After power-on starting, if the electronic device detects a Strap Pin (or other special keys, signals sent by these special keys or special combination keys can inform the electronic device to enter a download mode or a start loading mode) signal indicating that the electronic device enters the download mode, a download task is executed, otherwise, the electronic device enters the start loading mode, however, many electronic devices do not set the Strap Pin (or other special keys), and therefore, the working mode cannot be determined by detecting the Strap Pin (or other special keys) signal. Some electronic devices may support a command interaction mode to select an entry working mode, for example, after receiving a mode instruction of an upper computer (computer) through the command interaction mode, the electronic devices may directly enter a download mode or enter a start loading mode, and the command interaction mode has a disadvantage that: the electronic equipment does not know when the upper computer sends the instruction, but cannot wait for the mode instruction of the upper computer all the time, so that a fixed waiting time needs to be set, and the waiting time is set too long to influence the normal starting speed and too short to influence the working efficiency and experience, so that the electronic equipment has great disadvantages. Therefore, the method for selecting the working mode of the electronic equipment by adopting the related technology is not friendly, and the user experience is influenced.
And for the electronic equipment which is not provided with the Strap Pin (or other special keys) and does not support a command interaction mode, if the electronic equipment is powered on and cannot select a working mode after power failure or other abnormity occurs to cause shutdown when a system is installed or upgraded or under other conditions.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart illustrating an operation mode determination method according to an embodiment of the present disclosure.
The method is applied to an electronic device, which may include a terminal, a server, and the like, where the terminal is also referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like, and is a device that provides voice and/or data connectivity to a user, for example, a handheld device, a vehicle-mounted device, and the like having a wireless connection function. Currently, some examples of terminals are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), a wireless terminal in vehicle networking, and the like. Of course, the embodiment of the present disclosure does not limit the specific type and implementation manner of the electronic device, and a person skilled in the art may select the electronic device according to needs.
As shown in fig. 1, the method includes:
s11, after the electronic equipment is powered on, reading a Secondary boot Loader (SPL), wherein the SPL is a first-stage executive Program of the boot Loader Bootloader;
s12, determining the working mode of the electronic equipment according to the integrity of the SPL, wherein the working mode comprises a loading starting mode and a downloading mode.
Through the method, the working mode of the electronic equipment can be determined according to the integrity of the SPL, compared with the related technology that the working mode of the electronic equipment is determined through the Strap Pin (or other special keys) or the command interaction mode, the working mode determining method provided by the embodiment of the disclosure has the advantages of being simple in implementation mode, low in cost, safe and reliable, and capable of ensuring that the electronic equipment can normally work for the electronic equipment without the Strap Pin (or other special keys) or the command interaction mode, and when the electronic equipment is powered off due to power failure or other abnormal conditions, the working mode can be rapidly determined according to the integrity of the SPL after the electronic equipment is powered on and started.
The Bootloader may be a first segment program executed by the embedded system after being powered on, and may complete initialization of a processor (for example, a central processing unit CPU) of the electronic device and related hardware, and after the Bootloader completes initialization of the CPU and the related hardware, the Bootloader may load an operating system of the electronic device or a solidified embedded application program into a memory (for example, a RAM), and then jump to a space where the operating system is located, and start the operating system to run. In one example, bootloader may be a U-Boot or the like.
The SPL may move the code of the second stage of the Bootloader to a System memory (System Ram, also called an off-chip memory) of the electronic device for operation.
In one example, a boot loading mode, which may also be referred to as an "autonomous" mode, is initiated. In the boot load mode, the electronic device may run from loading the operating system into memory.
In one example, the downloading mode may refer to the electronic device downloading a target file (e.g., downloading a kernel image and a root file system image, etc.) from a target storage space (e.g., host) via a serial connection, a network connection, or a communication means.
In one example, the electronic device may be configured in advance to implement an integrity determination mode of operation from the SPL, which will be described in detail later.
The following describes an exemplary method for determining the different operating modes.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating an operation mode determining method according to an embodiment of the disclosure.
In a possible implementation manner, the step S12 of determining the operation mode of the electronic device according to the integrity of the SPL may include:
step S121, determining that the working mode of the electronic device is the download mode when the SPL is not complete.
In one example, the SPL incompleteness may include a plurality of cases, for example, the SPL incompleteness may include that a storage space storing the SPL is empty, that only a part of the SPL is in the storage space, that the SPL in the storage space is wrong, and the like, that is, the SPL incompleteness may include that a code of the SPL is incomplete, or that the code of the SPL cannot run normally, and a boot function of the SPL cannot be implemented.
In an example, the electronic device may determine whether the SPL is complete according to a comparison between the size of the SPL file and a preset size, for example, if the storage space for storing the SPL is empty, it may be determined that the SPL file does not exist, and the SPL is incomplete. And if the storage space for storing the SPL is not empty, judging whether the size of the SPL file is the same as the preset size or not, and if not, judging that the SPL is incomplete. Of course, the SPL file may also be compared with a preset SPL file to determine whether the SPL is complete, for example, the electronic device may compare the SPL file with the preset SPL file, and if the SPL file is different from the preset SPL file, it may be determined that the SPL file is incomplete.
Of course, the above description is exemplary, and the embodiment of the present disclosure does not limit a specific implementation of how to detect the integrity of the SPL, and in addition, the present disclosure does not limit the type and the location of the storage space for storing the SPL, and a person skilled in the art may determine the type and the location according to actual needs or specific situations.
Of course, the electronic device may be configured in advance to directly enter the downloading mode when the SPL is incomplete, which will be described later.
In one possible embodiment, as shown in fig. 2, the method may further include:
step S13, controlling the electronic equipment to enter the downloading mode so as to download the target file from the target storage space;
and step S14, after the target SPL file is downloaded from the target storage space, ending the downloading mode, wherein the target SPL file comprises a complete SPL.
In one example, the target storage space may be a HOST, an external storage device, and the disclosure is not limited thereto.
In the download mode, the electronic device may download the target file from the target storage space in a serial port manner, a wireless network, and other communication manners, which is not limited in this disclosure. Of course, the embodiment of the present disclosure does not limit the specific size and type of the target file, and those skilled in the art may determine the size and type according to needs or actual situations.
Because the working mode of the electronic device can be determined through the integrity of the SPL, the embodiment of the present disclosure can download the target SPL file at the last step of the whole downloading stage, so that when the electronic device needs to be maintained in the downloading mode (for example, system installation, system file update, and the like), the incomplete characteristic of the SPL can be maintained, and thus, even if the electronic device is powered off or restarted due to power failure or other abnormal conditions, after the electronic device is powered on again, the electronic device can quickly judge that the SPL is incomplete, and accordingly, the electronic device enters the downloading mode to continue downloading the target file.
In one example, when the downloading of the target SPL file as the last target file is completed, the entire downloading process may be considered to be completed, and thus the downloading mode may be terminated, in which case the electronic device may be automatically restarted or shut down. It is expected that, after the electronic device is started again, since the SPL file is updated to the complete target SPL file, the electronic device may enter the boot loading mode to start normally.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining a working mode according to an embodiment of the present disclosure.
In a possible implementation manner, the step S12 of determining the operation mode of the electronic device according to the integrity of the SPL may include:
step S123, determining that the operating mode of the electronic device is the start loading mode when the SPL is complete.
In one example, the SPL is complete, which may mean that the SPL file maintains integrity.
In one example, the electronic device may determine whether the SPL is complete according to a comparison between the size of the SPL file and a preset size, for example, if a storage space for storing the SPL is not empty, determine whether the size of the SPL file is the same as the preset size, and if the size is the same, determine that the SPL is complete. Of course, the SPL file may also be compared with a preset SPL file to determine whether the SPL is complete, for example, the electronic device compares the SPL file with the preset SPL file, and if the SPL file is the same as the preset SPL file, it may be determined that the SPL is complete.
Of course, the above description is exemplary, and the disclosure does not limit the specific implementation of how to detect the integrity of the SPL, and in addition, the disclosure does not limit the type and location of the storage space for storing the SPL, which can be determined by those skilled in the art according to actual needs or specific situations.

In one possible embodiment, as shown in fig. 3, the method may further include:
and S16, controlling the electronic equipment to enter the starting loading mode so that the electronic equipment enters an operating system.
When the SPL is complete, the electronic device may move the program of the second stage of the BootLoader to the memory through the SPL, so as to perform the next stage of starting until the operating system of the electronic device is successfully operated.
Of course, the present disclosure does not limit the operation mode of the boot loading mode and the normal boot mode of the electronic device, and those skilled in the art can learn by referring to the related art.
As can be seen from the above description, the working mode of the electronic device can be determined according to the integrity of the SPL in the embodiment of the present disclosure, and the working mode determining method provided in the embodiment of the present disclosure can ensure that the electronic device can work normally.
Of course, the disclosure is not limited thereto, and the working method determination method of the embodiment of the disclosure may also be combined with the related art, and the following description is made by exemplarily describing that the electronic device is provided with a Strap Pin or other special keys.

In a possible implementation manner, as shown in fig. 4, when the SPL is complete, if the electronic device has a Strap Pin or another special key, the embodiment of the present disclosure may also detect a signal of the Strap Pin or another special key, and if the signal of the Strap Pin or another special key indicates that the electronic device enters the download mode, the electronic device is controlled to enter the download mode, otherwise, the electronic device is controlled to enter the start loading mode, so as to normally start the electronic device.
Of course, the above description is exemplary and should not be construed as limiting the present disclosure.
The electronic device may be configured in advance to determine the mode of operation based on the integrity of the SPL, as exemplary described below.
