Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Before explaining the embodiments of the present disclosure in detail, an application scenario of the embodiments of the present disclosure will be described. At present, the flash mode of an intelligent terminal mainly has two modes, namely a Fastboot mode and a Recovery mode. Generally, when a user wants to flush the intelligent terminal through the Fastboot mode, the user can simultaneously press a power key and a volume down key of the intelligent terminal, and when the boot loader of the intelligent terminal detects that the power key and the volume down key are simultaneously pressed during the running process, the user enters the Fastboot mode. When a user wants to flush the intelligent terminal through the Recovery mode, the user can simultaneously press a power key and an upper volume key of the intelligent terminal, and when the boot loader of the intelligent terminal detects that the power key and the lower volume key are simultaneously pressed during operation, the user enters the Recovery mode. In the related art, the intelligent terminal needs to rely on the entity volume key to enter the flashing mode, and for the intelligent terminal without the entity volume key, the intelligent terminal cannot enter the flashing mode for flashing through the method, so that great inconvenience is brought to flashing of a user.
In order to solve the above problem, the embodiment of the present disclosure provides a flashing method of an intelligent terminal and the intelligent terminal. In the flashing method of the intelligent terminal, the intelligent terminal can determine whether to enter the flashing mode and which flashing mode to enter by detecting the grounding value on the CC pin of the configuration channel of the USB data line and comparing the grounding resistance value with the stored first preset resistance value and the second preset resistance value, so that the problem that the intelligent terminal cannot be flashed in the flashing mode when an entity volume key does not exist in the intelligent terminal in the related technology is solved, and convenience is brought to the use of a user.
Fig. 1 is a flowchart illustrating a flashing method of an intelligent terminal according to an exemplary embodiment, where the method is used in the intelligent terminal, as shown in fig. 1, and includes the following steps:
in step 101, when the boot loader runs, a ground value of a configuration channel pin of a currently connected USB data line is detected, where the USB data line is used to connect the intelligent terminal with another terminal.
In step 102, a flashing mode is determined based on the ground resistance value, the first preset resistance value and the second preset resistance value, and flashing is performed on the intelligent terminal in the flashing mode, wherein the first preset resistance value is not equal to the second preset resistance value.
In the implementation of the disclosure, when a boot loader of the intelligent terminal runs, the ground resistance value of the configuration channel pin of the USB data line is detected, and then the flashing mode is determined based on the detected ground resistance value, the first preset resistance value and the second preset resistance value. That is, the user can not need to enter the flashing mode by pressing the specific combination key of the intelligent terminal, so that the problem that the flashing mode cannot be entered to flash the intelligent terminal when the intelligent terminal does not have an entity volume key in the related art is solved, and convenience is brought to the flashing of the user.
Optionally, the determination of the brushing mode based on the ground resistance value, the first preset resistance value and the second preset resistance value includes:
judging whether the ground resistance value is equal to the first preset resistance value or not and judging whether the ground resistance value is equal to the second preset resistance value or not;
when the ground resistance value is equal to the first preset resistance value, determining that the flashing mode is a fast starting fastboost mode;
and when the ground resistance value is equal to the second preset resistance value, determining that the flashing mode is a Recovery mode.
Optionally, after determining whether the ground resistance is equal to the first resistance and determining whether the ground resistance is equal to the second resistance, the method further includes:
and when the ground resistance value is not equal to the first preset resistance value and the ground resistance value is not equal to the second preset resistance value, stopping detecting the ground resistance value of the configuration channel pin of the USB data line, and starting the intelligent terminal based on the boot loader.
Optionally, the channel pin is configured to be a CC pin, and the impedance to ground of the CC pin is greater than 126 kohms.
All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, and the embodiments of the present disclosure are not described in detail again.
Fig. 2 is a flashing method of an intelligent terminal according to an exemplary embodiment, and the method is used in the intelligent terminal, as shown in fig. 2, and includes the following steps:
in step 201, the intelligent terminal is connected with other terminals through the USB data line.
The USB data line may include two interfaces, one of which may be a class C interface designed based on the class C USB specification, and the other of which may be a class a interface designed based on the class a USB specification. Generally, the class a interface is mainly used for connecting with a computer, and the class C interface is mainly used for connecting with a mobile terminal such as a mobile phone.
When a user wants to flush the intelligent terminal, the intelligent terminal can be shut down, and then the intelligent terminal is connected with other terminals through a special USB data line. The A-type interface of the USB data line is connected with other terminals, and the C-type interface of the USB data line is connected with the intelligent terminal. And after the connection of the intelligent terminal and other terminals is completed, starting the intelligent terminal. Generally, when an intelligent terminal is started, a boot loader needs to be run first to complete various tasks such as initialization of hardware devices and loading and starting of a system, so as to complete the start.
In the process of starting the intelligent terminal, the intelligent terminal can be powered by a battery of the intelligent terminal when a power key is pressed, so that a guide loading program is operated. Of course, the intelligent terminal may also be powered by other intelligent terminals when connected with other terminals through the USB data line, so as to start running the boot loader. Wherein the other terminal can be a terminal such as a computer capable of communicating with the intelligent terminal through a USB data line.
It should be noted that the USB data line is a specially-made USB data line. The ground resistance value of a Configuration Channel (CC) pin in the class-C interface of the USB data line is greater than the ground resistance value of a CC pin in a common USB data line specified in the class-C USB specification. For a self-powered device or a device supporting error recovery, the ground resistance value of the CC pin in the normal USB data line specified in the class C USB specification is at least 126 kohm, and therefore, the ground resistance value of the CC pin in the special USB data line may be greater than 126 kohm. Other hardware settings of the USB data line are designed with reference to the class-C USB specification, and are not described in detail in the embodiment of the present disclosure.
In addition, since there is only one grounding value of the CC pin in each specially-made USB data line, and there are two types of the flashing modes, it is necessary to design USB data lines with different grounding values for different flashing modes in order to determine the flashing mode according to the grounding value. That is, when there are two flush modes, two USB data lines with different ground values need to be designed, and a user can select a corresponding USB data line to flush according to a flush mode that the user wants to enter. For example, assuming that a USB data line with a ground resistance of 200 kohms can enter the fastboost mode and a USB data line with a ground resistance of 220 kohms can enter the Recovery mode, when a user wants to perform a flash operation in the fastboost mode, the USB data line with a ground resistance of 200 kohms needs to be selected for the flash operation, and when the user wants to perform a flash operation in the Recovery mode, the USB data line with a ground resistance of 220 kohms needs to be selected for the flash operation.
In step 202, when the boot loader is running, the resistance value to ground of the configuration channel pin of the currently connected USB data line is detected.
Based on the description in step 201, when the intelligent terminal is connected to another terminal through the USB data line and the boot loader of the intelligent terminal starts to operate, the intelligent terminal may detect the resistance value to ground of the CC pin in the class C interface of the USB data line connected to the intelligent terminal.
Since the boot loader can only execute the operation of determining whether to enter the flash mode and which flash mode to enter only when the boot loader runs to a certain stage, and the intelligent terminal cannot determine when the stage is up in the process of running the boot loader, in order to ensure that the intelligent terminal can determine the flash mode at the stage, the intelligent terminal can detect the ground-to-ground value of the CC pin in the USB data line when the boot loader starts to run, and store the detected ground-to-ground value of the CC pin, so as to determine the flash mode through the ground-to-ground value later.
Certainly, the intelligent terminal can also read the earth resistance value of the CC pin in the USB data line at preset time intervals when the boot loader starts to run, so as to avoid the problem that the earth resistance value of the CC pin changes due to the temporary replacement of the USB data line during the running process of the boot loader by a user, and thus, an accurate earth resistance value of the CC pin can be provided for the subsequent determination of the flashing mode.
In step 203, a flashing mode is determined based on the ground resistance value, the first preset resistance value and the second preset resistance value, and flashing is performed on the intelligent terminal in the flashing mode, wherein the first preset resistance value is not equal to the second preset resistance value.
After the intelligent terminal detects the ground resistance value of the CC pin in the USB data line, when the boot loader runs to the step of determining the flashing mode, the intelligent terminal can determine the flashing mode based on the ground resistance value, the first preset resistance value and the second preset resistance value, and then the intelligent terminal is flashed in the determined flashing mode.
The intelligent terminal determines the operation mode of the flashing mode based on the ground resistance value, the first preset resistance value and the second preset resistance value, and the operation mode can be as follows: judging whether the ground resistance value is equal to the first preset resistance value or not and judging whether the ground resistance value is equal to the second preset resistance value or not; when the ground resistance value is equal to the first preset resistance value, determining that the flashing mode is a fastboost mode; and when the ground resistance value is equal to the second preset resistance value, determining that the flashing mode is the Recovery mode. And when the resistance value to the ground is not equal to the first preset resistance value and the resistance value to the ground is not equal to the second preset resistance value, stopping executing the step 202 and the step 203, and starting the intelligent terminal based on the boot loader.
The intelligent terminal can judge whether the ground resistance value is equal to the second preset resistance value or not while judging whether the ground resistance value is equal to the first preset resistance value or not, and therefore the judging speed is improved. Of course, since the first preset resistance value and the second preset resistance value are not equal to each other, if the ground resistance value is equal to one of the first preset resistance value and the second preset resistance value, the ground resistance value is not equal to the other resistance value, that is, the intelligent terminal does not need to judge whether the ground resistance value is equal to the other resistance value. Therefore, the intelligent terminal can firstly judge whether the ground resistance value is equal to the first preset resistance value or not, or firstly judge whether the ground resistance value is equal to the second preset resistance value or not, and when the ground resistance value is not equal to the first preset resistance value or when the ground resistance value is not equal to the second preset resistance value, then judge whether the ground resistance value is equal to the other preset resistance value or not, so that the judgment times of the intelligent terminal are reduced.
It should be noted that the first preset resistance value and the second preset resistance value are resistance values preset and stored in the intelligent terminal, and the first preset resistance value and the second preset resistance value correspond to different brusher modes respectively, for example, when the first preset resistance value corresponds to the Fastboot mode, the second preset resistance value corresponds to the Recovery mode. And the first preset resistance value and the second preset resistance value are set according to the ground resistance value of the CC pin in the specially-made USB data line. For example, the resistance to ground of the CC pin in one specially-made USB data line is 200 kilo-ohms, the resistance to ground of the CC pin in another specially-made USB data line is 220 kilo-ohms, and the intelligent terminal may set the first preset resistance to 200 kilo-ohms and the second preset resistance to 220 kilo-ohms, or of course, the first preset resistance may be set to 220 kilo-ohms and the second preset resistance may be set to 200 kilo-ohms. That is, when the first predetermined resistance value takes different values according to the ground value of the CC pin in the specially made USB data line, the USB data line required for entering the Fastboot mode is correspondingly different.
After the intelligent terminal determines the flashing mode, the intelligent terminal can be flashed based on the determined flashing mode. When the determined flashing mode is the Fastboot mode, the intelligent terminal can receive the system data file sent by other terminals connected with the intelligent terminal through the USB data line and update the system data file to a partition designated by the intelligent terminal, so that flashing is completed. And when the flashing mode is determined to be the Recovery mode, the intelligent terminal can modify the current system data through the system data in the memory of the intelligent terminal, so that flashing is completed.
In the embodiment of the disclosure, the intelligent terminal may determine whether to enter the flashing mode and which flashing mode to enter by detecting the ground resistance value on the CC pin of the configuration channel pin of the USB data line and comparing the ground resistance value with the stored first preset resistance value and the second preset resistance value, that is, the user may not enter the flashing mode by pressing the specific combination key of the intelligent terminal, so that the problem that the flashing mode cannot be entered to flash the intelligent terminal when the intelligent terminal does not have an entity volume key in the related art is solved, and convenience is brought to the user.
