Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
Referring to fig. 1, fig. 1 is a schematic diagram of an application environment of a terminal upgrading method in an embodiment. As shown in fig. 1, the application environment includes a USB bus 110, a terminal 120, and an upgrade apparatus 130.
Wherein the bus state of USB bus 110 is configured to trigger terminal 120 to enter an upgrade mode state. The terminal 120 includes a USB interface for connecting with the mating USB bus 110, and the terminal 120 is configured to determine whether it needs to enter an upgrade mode according to a pin status of the USB interface, so as to upgrade in the upgrade mode. The upgrade apparatus 130 is used to connect with a USB interface of the terminal 120 through the USB bus 110.
In this embodiment, when the terminal 120 needs to be upgraded, the upgrade apparatus 130 is connected to the USB interface of the terminal 120 through the USB bus 110, and since the bus state of the USB bus 110 is configured to trigger the terminal 120 to enter the upgrade mode and the USB interface is connected to the USB bus 110, the pin state of the corresponding USB interface may also change, so that the terminal 120 may determine whether to enter the upgrade mode according to the pin state of the USB interface.
In an embodiment, the upgrade apparatus 130 may be an apparatus for supplying power to the USB bus 110, and the bus state of the USB bus 110 is configured to trigger the terminal 120 to enter the upgrade mode, and since the bus state of the USB bus 110 is configured to trigger the terminal 120 to enter the upgrade mode, after the upgrade apparatus 130 is connected to the USB interface of the terminal 120 through the USB bus 110, the terminal 120 may determine whether the upgrade mode needs to be entered according to the pin state of the USB interface.
In one embodiment, the upgrade apparatus 130 is connected to the USB interface through the USB bus 110, and the bus state of the USB bus 110 is not configured to trigger the terminal 120 to enter the upgrade mode, at this time, the bus state of the USB bus 110 may be configured to trigger the terminal 120 to enter the upgrade mode through the upgrade apparatus 130, so that the terminal 120 may confirm whether the upgrade mode needs to be entered according to the pin state of the USB interface.
The following embodiments are explained on how to improve convenience of terminal upgrade.
Referring to fig. 2, fig. 2 is a flowchart illustrating a terminal upgrading method in an embodiment. The terminal upgrading method in this embodiment is described by taking the terminal in fig. 1 as an example. As shown in fig. 2, the terminal upgrade method includes steps 210 to 230.
And step 210, detecting the pin state of the USB interface.
The USB interface refers to an interface on the terminal. The USB interface includes, but is not limited to, a USB-A interface, a USB-B interface, and a USB-C interface, and is not limited thereto. Pin status refers to the status of a pin on the USB interface. Optionally, the pin status in this embodiment includes, but is not limited to, at least one of a VCC pin status, a DP pin status, a DM pin status, and a GND pin status, and this embodiment is not limited.
In this step, the triggering mode for the terminal to detect the pin state of the USB interface may be triggering when the terminal is powered on, that is, in the power-on process of the terminal, the terminal detects the pin state of the USB interface. In this embodiment, how to trigger the terminal to detect the pin status of the USB interface is not specifically limited.
And step 220, identifying whether the terminal needs to enter an upgrading mode according to the pin state.
Wherein, the upgrade mode refers to a mode in which the terminal enters an upgrade state. In this step, the terminal identifies whether it needs to enter the upgrade mode according to the pin status.
Step 230, responding to the identification result that the pin state represents that the terminal needs to enter the upgrading mode, entering the upgrading mode, and upgrading in the upgrading mode.
Optionally, the terminal needs to acquire the upgrade package first and upgrade the terminal by installing the upgrade package in the upgrade mode. It should be noted that, the manner of obtaining the upgrade package may be that the terminal downloads the installation package through a cellular network technology, or the terminal receives the installation package sent by the upgrade device through a USB bus, which is not limited in this embodiment. If the terminal receives the installation package sent by the upgrading device through the USB bus, the bus state of the USB bus needs to be configured into a state that the terminal is not triggered to enter the upgrading mode.
In this step, if the terminal recognizes that the pin state representation terminal needs to enter the upgrade mode, the terminal enters the upgrade mode, so as to perform upgrade in the upgrade mode.
According to the technical scheme of the embodiment, the pin state of the USB interface is detected, whether the terminal needs to enter the upgrading mode is identified according to the pin state, so that when the pin state represents that the terminal needs to enter the upgrading mode, the terminal enters the upgrading mode, upgrading is carried out in the upgrading mode, the terminal can judge whether the terminal needs to enter the upgrading mode according to the pin state of the USB interface, namely, the terminal enters the upgrading mode triggered by the pin state of the USB interface on the terminal, therefore, when the terminal needs to be upgraded, only the USB bus needs to be connected with the USB interface, and the USB bus is configured to trigger the terminal to enter the upgrading mode, at the moment, the pin state of the USB interface of the terminal changes and becomes the state representing that the terminal needs to enter the upgrading mode, and when the terminal determines that the pin state represents that the terminal needs to enter the upgrading mode, the terminal enters the upgrading mode for upgrading, the terminal can enter the upgrading mode without pressing a special key for a long time in the upgrading process of the terminal, and the technical effect of improving the convenience of terminal upgrading is achieved.
It can be understood that, by triggering the terminal upgrading method of the above embodiment when the terminal is started, that is, the terminal determines whether to enter the upgrading mode in the starting process, and if so, enters the upgrading mode for upgrading, even if the terminal cannot be started to enter the main interface, the terminal can be upgraded, and the terminal can also be upgraded when the terminal cannot be normally started, so that the convenience of terminal upgrading is further improved. Optionally, the triggering of the terminal upgrading method may be performed at the earliest stage of terminal booting, for example, at a BootLoader (boot load) stage of an Android platform.
It should be noted that, if the terminal upgrading method of the foregoing embodiment is triggered in the terminal booting process, when the pin state does not represent that the terminal needs to enter the upgrading mode, the terminal is normally booted, so as to enter the main interface.
In one embodiment, the pin status includes a DM pin status and/or a DP pin status. In this embodiment, the pin status includes a DM pin status and/or a DP pin status, that is, the terminal may determine whether to enter the upgrade mode according to the DM pin status, may also determine whether to enter the upgrade mode according to the DP pin status, and may also determine whether to enter the upgrade mode according to the DM pin status and the DP pin status. In this embodiment, identifying whether the terminal needs to enter an upgrade mode according to the pin status includes:
and if the DM pin state is consistent with a preset DM pin state and/or the DP pin state is consistent with a preset DP pin state, determining that the terminal needs to enter an upgrading mode.
Specifically, if the pin state includes a DM pin state, when the DM pin state is consistent with a preset DM pin state, the terminal enters an upgrade mode; if the pin state comprises a DP pin state, when the DP pin state is consistent with a preset DP pin state, the terminal enters an upgrading mode; and if the pin states comprise a DM pin state and a DP pin state, when the DM pin state is consistent with a preset DM pin state and the DP pin state is consistent with a preset DP pin state, the terminal enters an upgrading mode.
In this embodiment, since the terminal can identify whether the upgrade mode needs to be performed only by at least one of the DM pin state and the DP pin state, the DM pin state and the DP pin state do not bring hidden troubles to the security of the USB interface, and therefore the security of the terminal during upgrade can be improved.
It should be noted that the bus state of the USB bus may be adjusted to make the DM pin state of the USB interface consistent with the preset DM pin state, and/or make the DP pin state of the USB interface consistent with the preset DP pin state, so as to trigger the upgrade of the terminal.
Specifically, when the pin status is the DP pin status, the DP data line status of the USB bus is adjusted to be consistent with the preset DP data line status, and the preset DP data line status refers to that when the USB bus is connected to the USB interface, the DP pin status of the USB interface is consistent with the preset DP pin status. When the pin state is the DM pin state, the DM data line state of the USB bus is adjusted to be consistent with the preset DM data line state, and the preset DM data line state refers to the condition that when the USB bus is connected with the USB interface, the DM pin state of the USB interface is consistent with the preset DM pin state.
It can be understood that, when the pin states include the DM pin state and the DP pin state, that is, the terminal identifies whether to enter the upgrade mode through the DP pin state and the DM pin state, instead of simply relying on the DM pin state or the DP pin state, the problem of incorrect identification of the upgrade mode due to the change of the DM pin state or the DP pin state caused by normal operation can be eliminated, and the accuracy of entering the upgrade mode is improved.
For example, in The actual use process, for example, when an otg (on The go) connection peripheral (a usb disk, a mouse, a keyboard, etc.) is plugged in for starting up, The state of The DP pin may change, but at this time, The terminal should be normally started up, rather than entering The upgrade mode. Therefore, whether the upgrade mode needs to be entered is identified by the DP pin state and the DM pin state, and the accuracy of entering the upgrade mode can be improved.
In one embodiment, the predetermined DM pin status is that the DM pin is at a high level, and the predetermined DP pin status is that the DP pin is at a low level.
It is an electrical engineering term to refer to a high voltage as opposed to a low level. Among the logic levels, the minimum input high level allowed when the input of the logic gate is a high level is guaranteed, and when the input level is higher than the input high voltage (Vih), the input level is considered as a high level. A low level (Vil) refers to the maximum input low level allowed when the input to the logic gate is guaranteed to be low, and when the input level is lower than Vil, the input level is considered low. Generally, the low level is 0V, i.e. short circuit; the high level is 1.8V. The DP data line and the DM data line of the USB bus may be respectively connected to an interface, and when in use, the DP data line is grounded and short-circuited, and the DM data line is connected to a high level (generally 1.8V).
It should be noted that, if the DM pin is preset to be at a high level, the DM data line state of the USB bus is correspondingly at a high level. Similarly, if the predetermined DP pin state is the DP pin state at the low level, the corresponding DP data line state of the USB bus is at the low level.
In some cases, the pin state of the USB interface indicates that the terminal needs to enter the upgrade mode, not necessarily because the USB bus is configured to trigger the terminal to enter the upgrade mode, and the pin state of the USB interface jumps to a state indicating that the terminal needs to enter the upgrade mode due to an environment where the terminal is located or some abnormality occurs in the terminal itself, but in this case, according to the terminal upgrade method of the foregoing embodiment, the terminal still enters the upgrade mode, but in this case, the terminal does not need to enter the upgrade mode, and if the terminal enters the upgrade mode, the terminal may be damaged. Therefore, it is required to improve the recognition accuracy of the terminal entering the upgrade mode.
The following embodiments are provided to explain how to improve the identification accuracy of the terminal entering the upgrade mode based on any of the above embodiments.
Referring to fig. 3, fig. 3 is a schematic flowchart of a terminal upgrading method in another embodiment. In this embodiment, it is detected whether the USB interface is connected to the USB bus before detecting the pin status of the USB interface. As shown in fig. 3, the terminal upgrade method includes steps 310 to 340.
And step 310, detecting whether the USB interface is connected with a USB bus.
In this step, the terminal detects whether the USB interface is connected to the USB bus.
And step 320, responding to the detection result that the USB interface is connected with the USB bus, and detecting the pin state of the USB interface.
In this step, the pin status of the USB interface is detected only when it is detected that the USB bus is connected to the USB interface. In this embodiment, for the step of detecting the pin status of the USB interface, reference may be made to the description of any of the above embodiments, which is not described in detail in this embodiment.
And step 330, identifying whether the terminal needs to enter an upgrading mode according to the pin state.
This step may refer to the description of any of the above embodiments, which is not repeated herein.
It is understood that if the USB interface is detected to be connected to the USB bus, it may be considered that the terminal needs to be upgraded in the current situation, charged, or in other situations. However, if the pin status also indicates that the terminal needs to enter the upgrade mode, it can be basically determined that the terminal needs to enter the upgrade mode, rather than the misjudgment caused by the environment where the terminal is located or some abnormality occurs in the terminal itself.
Step 340, responding to the identification result that the pin state represents that the terminal needs to enter the upgrading mode, entering the upgrading mode, and upgrading in the upgrading mode.
This step may refer to the description of any of the above embodiments, which is not repeated herein.
According to the technical scheme of the embodiment, whether the USB interface is connected with the USB bus or not is detected, and if the USB interface is connected with the USB bus, the pin state of the USB interface is detected, so that whether the USB interface needs to enter the upgrading mode or not is identified according to the pin state of the USB interface, and if the USB interface is connected with the USB bus, the terminal may be considered to be required to be upgraded, charged or in other situations in the current situation. However, if the pin state also indicates that the terminal needs to enter the upgrade mode, the terminal can be basically determined to need to enter the upgrade mode, instead of being misjudged due to the environment where the terminal is located or some abnormality occurs in the terminal itself, so that the identification accuracy of the terminal entering the upgrade mode is improved, and the security of the terminal is correspondingly improved.
In one embodiment, the detecting whether the USB bus is connected to the USB interface includes:
detecting whether a VBUS pin of the USB interface is effective or not; and if the VBUS pin of the USB interface is valid, determining that the USB interface is connected with the USB bus.
The VBUS pin refers to a pin for receiving power supply in the USB interface. In this embodiment, if the VBUS pin is valid, it indicates that the USB bus supplies power to the USB interface, and at this time, the USB interface may be considered to be connected to the USB bus. Accordingly, the USB bus supplies power to the VBUS pin of the USB interface through the VBUS line. The VBUS line is the power line that HOST/HUB supplies to the USB device, i.e., +5V of an ordinary USB device.
In this embodiment, whether the VBUS pin of the USB interface is valid is detected, and if so, it is determined that the USB interface is connected to the USB bus, and whether the USB interface is connected to the USB bus can be determined by detecting the validity of the VBUS pin, so that the detection means is simple and easy to implement. It should be noted that, in general, the validity detection of the VBUS pin can be realized by reading the on-site detection of the battery.
Referring to fig. 4, fig. 4 is a schematic flowchart of a terminal upgrading method in another embodiment. In this embodiment, it is detected whether the charging type of the battery of the terminal is normal before detecting the pin status of the USB interface. As shown in fig. 4, the terminal upgrade method includes steps 410 to 440.
And step 410, detecting whether the charging type of the battery of the terminal is normal.
The charging type refers to a type of charging the battery, and is related to a charging protocol. The charging type of the present embodiment includes, but is not limited to, an SDP charging type, a CDP charging type, a DCP charging type, and the like, and is not limited herein. When the SDP charging type is suspended, the maximum load current is 2.5 mA; 100mA in the connected and non-suspended state, a current of 500mA (max) can be configured. The device may recognize the SDP using hardware, with the USB data lines D + and D-each grounded through 15k Ω, but still requiring enumeration to comply with the USB specification. The CDP charging type can provide up to 1.5A current, as can be provided prior to enumeration, unlike USB 2.0. Devices inserted into the CDP may identify the CDP by manipulating and monitoring the D +, D-lines using hardware handshaking. Hardware testing is performed before the data line is switched to USB transceiving, so that CDP (and charging is initiated) can be detected before enumeration. DCP charging types can provide up to 1.5A current, identified by short circuits D + and D-, enabling the design of DCP "wall adapter power", using USB mini or micro jacks instead of round plugs or self-made connector fixed mounting wires. Such an adapter can be charged using any USB cable (equipped with the correct plug).
And step 420, responding to the detection result that the charging type is normal, and detecting the pin state of the USB interface.
In this step, the pin status of the USB interface is detected only when the charging type is detected to be normal. In this embodiment, for the step of detecting the pin status of the USB interface, reference may be made to the description of any of the above embodiments, which is not described in detail in this embodiment.
And 430, identifying whether the terminal needs to enter an upgrading mode according to the pin state.
In this step, reference may be made to the description of any one of the above embodiments, which is not repeated herein. It is understood that if the charging type is detected to be normal, it may be considered that the terminal needs to be upgraded in the current situation, the terminal may be charging, or other situations. However, if the pin status also indicates that the terminal needs to enter the upgrade mode, it can be basically determined that the terminal needs to enter the upgrade mode, rather than the misjudgment caused by the environment where the terminal is located or some abnormality occurs in the terminal itself.
And 440, responding to the identification result that the pin state represents that the terminal needs to enter an upgrading mode, entering the upgrading mode, and upgrading in the upgrading mode.
This step may refer to the description of any of the above embodiments, which is not repeated herein. According to the technical scheme of the embodiment, whether the charging type of the battery of the terminal is normal is detected, if the charging type is normal, the terminal detects the pin state of the USB interface, so that whether the terminal needs to enter the upgrading mode is identified according to the pin state of the USB interface, and if the charging type of the battery is detected to be normal, the terminal may need to be upgraded, the terminal may be charged or other situations may be considered in the current situation. However, if the pin state also indicates that the terminal needs to enter the upgrade mode, the terminal can be basically determined to need to enter the upgrade mode, instead of being misjudged due to the environment where the terminal is located or some abnormality occurs in the terminal itself, so that the identification accuracy of the terminal entering the upgrade mode is improved, and the security of the terminal is correspondingly improved.
