Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element.

Referring to FIG. 1 , FIG. 1 is a schematic diagram of an application environment of a method for upgrading a terminal in an embodiment. As shown in FIG. 1 , the application environment includes a USB bus 110 , a terminal 120 and an upgrade device 130 .

Wherein, the bus status of the USB bus 110 is configured as a status that triggers the terminal 120 to enter the upgrade mode. The terminal 120 includes a USB interface, and the USB interface is used to connect with the corresponding USB bus 110. The terminal 120 is used to determine whether to enter the upgrade mode according to the pin state of the USB interface, so as to upgrade in the upgrade mode. The upgrading device 130 is used to connect with the USB interface of the terminal 120 through the USB bus 110 .

In this embodiment, when the terminal 120 needs to be upgraded, the upgrade device 130 is connected to the USB interface of the terminal 120 through the USB bus 110, because the bus status 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 , so the pin state of the corresponding USB interface will also change, so the terminal 120 can determine whether to enter the upgrade mode according to the pin state of the USB interface.

In one embodiment, the upgrade device 130 can be a device that supplies power to the USB bus 110, and the bus state of the USB bus 110 is configured to trigger the state that the terminal 120 enters the upgrade mode, because the bus state of the USB bus 110 is configured to trigger When the terminal 120 enters the upgrade mode, after the upgrade device 130 is connected to the USB interface of the terminal 120 through the USB bus 110, the terminal 120 can confirm whether to enter the upgrade mode according to the pin state of the USB interface.

In one embodiment, the upgrade device 130 is connected to the USB interface through the USB bus 110, and the bus state of the USB bus 110 is not configured as a state that triggers the terminal 120 to enter the upgrade mode. The bus status is configured to trigger the terminal 120 to enter the upgrade mode, so that the terminal 120 can confirm whether to enter the upgrade mode according to the pin status of the USB interface.

The following embodiments illustrate how to improve the convenience of terminal upgrade.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a method for upgrading a terminal in an embodiment. The terminal upgrade method in this embodiment is described by taking the terminal running on the terminal in FIG. 1 as an example. As shown in FIG. 2 , the terminal upgrading method includes step 210 to step 230 .

Step 210, detecting the state of the pins of the USB interface.

Wherein, 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, which are not limited here. The pin status refers to the status of the pins on the USB interface. Optionally, the pin state in this embodiment includes but not limited to at least one of the VCC pin state, the DP pin state, the DM pin state, and the GND pin state, which is not limited in this embodiment.

In this step, the trigger mode for the terminal to detect the state of the pins of the USB interface may be triggered when the terminal is turned on, that is, during the booting process of the terminal, the terminal detects the state of the pins of the USB interface. In this embodiment, there is no specific limitation on how to trigger the terminal to detect the state of the pins of the USB interface.

Step 220, identifying whether the terminal needs to enter the upgrade mode according to the state of the pin.

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 state of the pin.

Step 230: Enter the upgrade mode in response to the recognition result that the pin state indicates that the terminal needs to enter the upgrade mode, and perform upgrade in the upgrade mode.

Optionally, the way to upgrade the terminal in the upgrade mode is that the upgrade package needs to be obtained first, and the upgrade is performed by installing the upgrade package. It should be noted that the way to obtain the upgrade package may be that the terminal downloads the installation package through the cellular network technology, or the terminal receives the installation package sent by the upgrade device through the USB bus, which is not limited in this embodiment. When the terminal receives the installation package sent by the upgrade device through the USB bus, the bus state of the USB bus needs to be configured to not trigger the terminal to enter the upgrade mode.

In this step, when the terminal recognizes that the pin state indicates that the terminal needs to enter the upgrade mode, the terminal enters the upgrade mode, so as to perform upgrade in the upgrade mode.

In the technical solution of this embodiment, by detecting the pin state of the USB interface, and identifying whether the terminal needs to enter the upgrade mode according to the pin state, when the pin state indicates that the terminal needs to enter the upgrade mode, the terminal enters the upgrade mode, thereby upgrading Upgrade in mode, because the terminal can judge whether to enter the upgrade mode according to the pin state of the USB interface, that is, the entry of the upgrade mode of the terminal is triggered by the pin state of the USB interface on the terminal, so when it is necessary to update the terminal When upgrading, you only need to connect the USB bus to the USB interface, and configure the USB bus to trigger the terminal to enter the upgrade mode. At this time, the pin status of the USB interface of the terminal will also change, indicating that the terminal needs to enter The state of the upgrade mode, when the terminal determines that the pin status indicates that the terminal needs to enter the upgrade mode, the terminal enters the upgrade mode to upgrade. During the upgrade process of the terminal, it is not necessary to press and hold the special button to make the terminal enter the upgrade mode. , achieving the technical effect of improving the convenience of terminal upgrades.

It can be understood that by triggering the terminal upgrade method of the above embodiment when the terminal is powered on, that is, the terminal judges whether it needs to enter the upgrade mode during the boot process, and if necessary, enters the upgrade mode to perform the upgrade, even if the boot cannot be completed and enters the main interface, the terminal can also be upgraded, and the terminal can also be upgraded when the terminal cannot be started normally, which further improves the convenience of terminal upgrade. Optionally, the terminal upgrade method can be triggered at the earliest stage of terminal startup, such as the BootLoader (boot loading) stage of the Android (Android) platform.

It should be noted that when the terminal upgrade method of the above embodiment is triggered during the booting process of the terminal, when the pin status does not indicate that the terminal needs to enter the upgrade mode, the terminal starts up normally and enters the main interface.

In one embodiment, the pin status includes DM pin status and/or DP pin status. In this embodiment, the pin state includes the DM pin state and/or the DP pin state, that is, the terminal can determine whether to enter the upgrade mode according to the DM pin state, or the terminal can determine whether it needs to enter the upgrade mode according to the DP pin state. Entering the upgrade mode may also be that the terminal determines whether to enter the upgrade mode according to the state of the DM pin and the state of the DP pin. In this embodiment, identifying whether the terminal needs to enter the upgrade mode according to the pin status includes:

Specifically, when the pin state includes the DM pin state, when the DM pin state is consistent with the preset DM pin state, the terminal enters the upgrade mode; when the pin state includes the DP pin state, then when the DP pin state When it is consistent with the preset DP pin state, the terminal enters the upgrade mode; when the pin state includes DM pin state and DP pin state, then when the DM pin state is consistent with the preset DM pin state, and the DP pin state When the state of the preset DP pin is consistent, the terminal enters the upgrade mode.

In this embodiment, because the terminal can only identify whether it needs to perform an upgrade mode through at least one of the DM pin state and the DP pin state, and the DM pin state and the DP pin state will not affect the security of the USB interface. It brings hidden dangers, so it can improve the security when the terminal is upgraded.

It should be noted that the bus state of the USB bus can 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 , thus triggering the upgrade of the terminal.

Specifically, when the pin state is the DP pin state, the DP data line state of the USB bus is adjusted to be consistent with the preset DP data line state. The preset DP data line state refers to when the USB bus is connected to the USB interface. , which can make the state of the DP pin of the USB interface consistent with the state of the preset DP pin. When the pin state is the DM pin state, adjust the DM data line state of the USB bus to be consistent with the preset DM data line state. The preset DM data line state means that when the USB bus is connected to the USB interface, it can make The DM pin state of the USB interface is consistent with the preset DM pin state.

It can be understood that when the pin status includes the DM pin status and the DP pin status, that is, the terminal recognizes whether it needs to enter the upgrade mode through the DP pin status and the DM pin status, instead of simply relying on the DM pin status Or DP pin state, can eliminate the problem of DM pin state or DP pin state change caused by normal operation, which leads to the misidentification of the upgrade mode, and improves the accuracy of entering the upgrade mode.

Exemplary, in actual use, for example, plugging in OTG (On The Go) to connect peripherals (U disk, mouse, keyboard, etc.) Instead of going into upgrade mode. Therefore, identifying whether to enter the upgrade mode through the DP pin state and the DM pin state can improve the accuracy of entering the upgrade mode.

In one embodiment, the preset state of the DM pin is that the DM pin is at a high level, and the preset state of the DP pin is that the DP pin is at a low level.

Among them, it refers to the high voltage relative to the low level, which is a term in electrical engineering. In the logic level, the minimum input high level allowed when the input of the logic gate is guaranteed to be high. When the input level is higher than the input high voltage (Vih), the input level is considered to be high. Low level (Vil) refers to the maximum input low level allowed when the input of the logic gate is guaranteed to be low level. When the input level is lower than Vil, the input level is considered to be low level. Generally, the low level is 0V, that is, short circuit; the high level is 1.8V. The DP data line and DM data line of the USB bus can be left out of the interface respectively, and the DP data line is grounded and short-circuited when in use, and the DM data line is connected to a high level (usually 1.8V).

It should be noted that the preset state of the DM pin is that the DM pin is at a high level, and correspondingly, the state of the DM data line of the USB bus is at a high level. Similarly, the default state of the DP pin is that the state of the DP pin is at a low level, and correspondingly, the state of the DP data line of the USB bus is at a 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 as a state that triggers the terminal to enter the upgrade mode, and the USB interface is connected to the USB bus, it may be because the terminal environment, or some abnormality occurs in the terminal itself, which causes the pin state of the USB interface to jump to a state indicating that the terminal needs to enter the upgrade mode, but in this case, according to the terminal upgrade method of the above-mentioned embodiment, the terminal still It will enter the upgrade mode, but in this case, it is not necessary for the terminal to enter the upgrade mode. When the terminal enters the upgrade mode, it will cause damage to the terminal. Therefore, it is necessary to improve the recognition accuracy of the terminal entering the upgrade mode.

The following embodiments describe how to improve the recognition accuracy of the terminal entering the upgrade mode on the basis of any of the above embodiments.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a method for upgrading a terminal in another embodiment. In this embodiment, before detecting the state of the pins of the USB interface, it is detected whether the USB interface is connected to the USB bus. As shown in FIG. 3 , the terminal upgrading method includes step 310 to step 340 .

Step 310, detecting whether the USB interface is connected to a USB bus.

In this step, the terminal detects whether the USB interface is connected to the USB bus.

Step 320 , in response to the detection result that the USB interface is connected to the USB bus, detect the state of the pins of the USB interface.

In this step, when the terminal detects that the USB interface is connected to the USB bus, it detects the pin status of the USB interface. In this embodiment, for the step of detecting the state of the pins of the USB interface, reference may be made to the description of any of the foregoing embodiments, and details are not described in this embodiment.

Step 330, identifying whether the terminal needs to enter the upgrade mode according to the state of the pin.

For this step, reference may be made to the description of any of the foregoing embodiments, and details are not described in this embodiment.

It can be understood that when the terminal detects that the USB interface is connected to the USB bus, it can be considered that in the current situation, the terminal may need to be upgraded, it may be charging, or other circumstances. 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, and it is not a misjudgment caused by the environment of the terminal or some abnormality of the terminal itself.

Step 340: Enter the upgrade mode in response to the recognition result that the pin state indicates that the terminal needs to enter the upgrade mode, and perform upgrade in the upgrade mode.

In the technical scheme of this embodiment, by first detecting whether the USB interface is connected to the USB bus, when it is detected that the USB interface is connected to the USB bus, the pin state of the USB interface is detected, so as to identify whether it is necessary to enter the USB interface according to the pin state of the USB interface. Upgrade mode, when it is detected that the USB interface is connected to the USB bus, it can be considered that in the current situation, the terminal may need to be upgraded, it 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, not because of the environment in which the terminal is located, or a misjudgment caused by some abnormalities in the terminal itself. In order to improve the identification accuracy of the terminal entering the upgrade mode, the security of the terminal is also improved correspondingly.

In one embodiment, detecting whether the USB interface is connected to a USB bus includes:

Detect whether the VBUS pin of the USB interface is valid; when the VBUS pin of the USB interface is valid, it is determined that the USB interface is connected to the USB bus.

Wherein, the VBUS pin refers to a pin used for receiving power supply in the USB interface. In this embodiment, if the VBUS pin is valid, it means that there is a USB bus to supply power to the USB interface, and at this time it can be considered that the USB interface is connected to the USB bus. Correspondingly, the USB bus is powered by the VBUS line to the VBUS pin of the USB interface. The VBUS line is the power line for the HOST/HUB to supply power to the USB device, that is, the +5V of the normal USB device.

In this embodiment, the terminal detects whether the VBUS pin of the USB interface is valid, and when it is valid, the terminal determines that the USB interface is connected to the USB bus, and can determine whether the USB interface is connected to the USB bus through the validity detection of the VBUS pin , the detection method is simple and easy. It should be noted that, generally, the validity detection of the VBUS pin can be realized by reading the presence detection of the battery.

Referring to FIG. 4 , FIG. 4 is a schematic flowchart of a method for upgrading a terminal in another embodiment. In this embodiment, before detecting the state of the pins of the USB interface, it is detected whether the charging type of the battery of the terminal is normal. As shown in FIG. 4 , the terminal upgrading method includes step 410 to step 440 .

Step 410, detecting whether the charging type of the battery of the terminal is normal.

Wherein, the charging type refers to the charging type of the battery, which is related to the charging protocol. The charging type in this embodiment includes, but is not limited to, the SDP charging type, the CDP charging type, and the DCP charging type, etc., which are not limited here. When the SDP charging type is suspended, the maximum load current is 2.5mA; when it is connected and not suspended, it is 100mA, and the current can be configured to be 500mA (maximum). The device can use hardware to identify SDP, and the USB data lines D+ and D- are respectively grounded through 15kΩ, but they still need to be enumerated to comply with the USB specification. The CDP charging type can provide up to 1.5A, which is different from USB 2.0 because the current can be provided before enumeration. A device plugged into a CDP can identify the CDP using hardware handshaking by manipulating and monitoring the D+, D- lines. Perform a hardware test before converting the data line to USB, so that the CDP can be detected (and start charging) before enumeration. The DCP charging type can deliver up to 1.5A and is identified by shorting D+ and D-, enabling the design of a DCP "wall adapter power supply" with a USB mini or mini-jack instead of a round plug or a fixed installation of a homemade connector Wire. Such an adapter can be charged with any USB cable (equipped with the correct plug).

Step 420 , in response to the detection result that the charging type is normal, detect the pin status of the USB interface.

In this step, when the terminal detects that the charging type is normal, it detects the pin state of the USB interface. In this embodiment, for the step of detecting the state of the pins of the USB interface, reference may be made to the description of any of the foregoing embodiments, and details are not described in this embodiment.

Step 430, identifying whether the terminal needs to enter the upgrade mode according to the state of the pin.

In this step, for this step, reference may be made to the description of any of the foregoing embodiments, and details are not described in this embodiment. It can be understood that when it is detected that the charging type is normal, it can be considered that the terminal needs to be upgraded in the current situation, it 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, and it is not a misjudgment caused by the environment of the terminal or some abnormality of the terminal itself.

Step 440: Enter the upgrade mode in response to the recognition result that the pin state indicates that the terminal needs to enter the upgrade mode, and perform upgrade in the upgrade mode.

For this step, reference may be made to the description of any of the foregoing embodiments, and details are not described in this embodiment. In the technical solution of this embodiment, the terminal first detects whether the charging type of the battery of the terminal is normal, and when the charging type is normal, the terminal detects the pin state of the USB interface, thereby identifying whether it needs to enter the upgrade mode according to the pin state of the USB interface , when the terminal detects that the charging type of the battery is normal, it can be considered that in the current situation, the terminal may need to be upgraded, or it may be charging, or other circumstances. 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, not because of the environment in which the terminal is located, or a misjudgment caused by some abnormalities in the terminal itself. In order to improve the identification accuracy of the terminal entering the upgrade mode, the security of the terminal is also improved correspondingly. In addition, when the battery charging type of the terminal is normal, it can avoid the loss caused by charging to the machine when the charging type detection is abnormal, and can also protect the battery of the terminal, and at the same time avoid the problem of abnormal charging failure and upgrade failure, ensuring the terminal safety.

In one embodiment, detecting whether the charging type of the battery of the terminal is normal includes: identifying whether the charging type is an SDP charging type, a CDP charging type or a DCP charging type; when the charging type is an SDP charging type, a CDP charging type or a DCP charging type , it is determined that the charging type of the battery is normal.

In this embodiment, by identifying whether the charging type is SDP charging type, CDP charging type or DCP charging type, when the charging type is SDP charging type, CDP charging type or DCP charging type, it is determined that the charging type of the battery is normal, then It can ensure that the terminal is charged with a better charging method, ensuring the security of the terminal upgrade.

It should be noted that the terminal can identify the charging type of the battery by detecting the change of the charging signal, which is not specifically limited in this embodiment.

In one embodiment, before the terminal detects the pin state of the USB interface, it can also detect whether the USB interface is connected to the USB bus, and detect whether the charging type of the battery of the terminal is normal. When it is detected that the USB interface is connected to the USB bus, And when it is detected that the charging type of the battery of the terminal is normal, the pin state of the USB interface is detected.

It can be understood that by detecting whether the USB interface is connected to the USB bus and detecting whether the charging type of the battery of the terminal is normal, it is equivalent to using multiple detections to determine that the terminal is indeed connected to the upgrade device through the USB bus to ensure that the terminal enters the identification of the upgrade mode Accuracy is maximized.

Referring to FIG. 5 , FIG. 5 is a schematic flowchart of a method for upgrading a terminal in another embodiment. In this embodiment, the terminal upgrade method is triggered during the boot process as an example for illustration. As shown in FIG. 5 , the terminal upgrading method includes step 510 to step 580 .

Step 510, start booting.

Step 520, detecting whether the USB interface is connected to the USB bus.

In this step, when the terminal detects that the USB interface is connected to the USB bus, step 530 is executed. When the terminal does not detect that the USB interface is connected to the USB bus, step 580 is executed.

Step 530, detecting whether the charging type of the battery of the terminal is normal.

In this step, when the terminal detects that the charging type of the battery of the terminal is normal, step 540 is performed. When the terminal detects that the charging type of the battery is abnormal, step 580 is executed.

Step 540, detecting the state of the DP pin and the state of the DM pin of the USB interface.

Step 550, judging whether the state of the DP pin is at low level.

In this step, when the state of the DP pin is at low level, step 560 is executed. If not, go to step 580 .

Step 560, judging whether the state of the DM pin is at a high level.

In this step, when the state of the DM pin is at a high level, step 570 is performed. If not, go to step 580 .

Step 570, enter the upgrade mode, and perform the upgrade in the upgrade mode.

Step 580, start up normally.

It should be noted that the order of

steps

550 and 560 can be reversed.

In the technical solution of this embodiment, since the terminal can judge whether it needs to enter the upgrade mode according to the pin state of the USB interface, that is, the entry of the upgrade mode of the terminal is triggered by the pin state of the USB interface on the terminal, so when needed When upgrading the terminal, you only need to connect the USB bus to the USB interface, and configure the USB bus to trigger the terminal to enter the upgrade mode. At this time, the pin status of the USB interface of the terminal will also change and become a representative terminal. When the terminal needs to enter the upgrade mode, the terminal enters the upgrade mode to upgrade when the pin status is determined to indicate that the terminal needs to enter the upgrade mode.
