Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The boot process is critical to the electronic device. In the booting process, the power-on timing signal sent by the south bridge chip is particularly important, where the power-on timing signal is used to instruct the electronic device to supply power to each functional module (such as a system bus, a memory module, a Central Processing Unit (CPU), and the like) according to a preset power supply sequence. At present, there are two kinds of power supplies for supplying power to an electronic device, one of them is a Real-time clock (RTC) power supply included in the electronic device, which is usually a RTC button battery, and is used for supplying power to a Management Engine (ME) module built in a south bridge chip, so as to maintain Complementary Metal Oxide Semiconductor (CMOS) configuration information stored in the ME module, such as hardware configuration parameters of the electronic device (e.g., working voltages of various functional modules, power supply sequences preset for various functional modules, etc.), boot parameters (e.g., current date, current time, boot settings, etc.), and parameters set by a user (e.g., system password, etc.). The other type is an external power supply which is used for supplying power to each functional module in the electronic equipment. Under the condition that the external power supply of the electronic device does not supply power, only the RTC power supply inside the electronic device operates to maintain CMOS configuration information, such as updating of time parameters and the like, so that the electronic device can be configured based on the CMOS configuration information when being started.
The starting process of the electronic equipment is specifically as follows: when the external power supply is connected, the controller in the electronic equipment resets and starts to work, and a user is waited to trigger a starting instruction. When the controller detects a power-on instruction triggered by a user, a power-on signal (PWRBTN #) is sent to the south bridge, so that after the south bridge receives the signal PWRBTN #, an ME module arranged in a south bridge chip sends a power-on sequence signal to the controller to indicate the controller to convert the voltage provided by a power supply into working voltage of each functional module on the mainboard in sequence, and power is supplied to each functional module on the mainboard in sequence according to the corresponding relation between the functional module and the working voltage. And when the controller supplies power to all the functional modules on the mainboard, the electronic equipment is configured based on the CMOS configuration information stored in the ME module. It can be seen that the south bridge chip plays an important role in the booting process of the electronic device based on the X86 architecture.
However, when the south bridge chip encounters an abnormal environment (such as an electrostatic environment), data stored in the south bridge chip is abnormal, which causes an abnormal power-on timing signal sent by the south bridge chip to the electronic device, so that the electronic device cannot be normally powered on. Accordingly, embodiments of the present invention provide an electronic device booting method and an electronic device, so as to solve a problem in the prior art that the electronic device cannot be normally booted due to an abnormal environment encountered by a south bridge chip. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

Based on the electronic device shown in fig. 1, an embodiment of the present invention provides a method for starting up an electronic device, and as shown in fig. 2, the method for starting up an electronic device may specifically include the following steps:
s201, the control module receives a first power-on time sequence signal sent by a starting module;
s202, when the control module determines that the working state of the starting-up module is abnormal according to the first power-on time sequence signal, the control module restores the data stored in the starting-up module to initial data.
S203, the control module receives a second power-on time sequence signal sent by the starting module according to the initial data.
S204, the control module starts the electronic equipment based on the second power-on sequence signal.
In the embodiment of the invention, when the control module determines that the working state of the starting module is abnormal, the data stored in the starting module is recovered to the initial data, so that the starting module sends the second power-on time sequence signal based on the initial data, and then the control module starts the electronic equipment based on the second power-on time sequence signal, thereby effectively solving the problem that the electronic equipment cannot be normally started due to the abnormal power-on time sequence signal sent to the electronic equipment by the south bridge chip caused by the abnormal stored data when the south bridge chip encounters an abnormal environment, improving the system performance of the electronic equipment and improving the use experience of a user.
In a possible implementation manner, after a boot instruction triggered by a user is received and before the working state of the boot module is determined to be abnormal, the control module starts the boot module, so that the boot module sends a first power-on timing sequence signal to the control module after being started.
Specifically, the control module may control the conversion module to convert the voltage provided by the external power supply into a working voltage of the power-on module through the third IO signal and provide the working voltage to the power-on module, and when the voltage converted by the conversion module is stabilized at the working voltage of the power-on module, the power-on module is started.
Optionally, after the boot module is started, if the control module determines that the working state of the boot module is abnormal according to the first power-on timing signal, the control module restores the data stored in the boot module to the initial data.
The control module determines that the working state of the starting-up module is abnormal according to the first power-on time sequence signal, and the method can be realized in the following way: and the control module determines that the working state of the starting-up module is abnormal when the first power-on time sequence signal is determined to be at a low level.
Specifically, the control module may periodically detect whether the first power-on timing signal is at a high level. And when detecting that the first power-on time sequence signal is at a low level, the control module determines that the working state of the starting-up module is abnormal.
The control module restores the data stored in the starting module to the initial data, and the restoration can be realized by the following modes: the control module controls the real-time clock (RTC) power supply to stop supplying power to the starting module, and controls the RTC power supply to continuously supply power to the starting module after preset time.
Specifically, the control module may control the switch module to stop transmitting the electric energy provided by the RTC power supply to the power-on module through the second IO signal. Because the RTC power supply is used for supplying power to the starting module to maintain the data stored in the starting module, when the switch module stops transmitting the electric energy provided by the RTC power supply to the starting module, the data stored in the starting module is recovered to the initial data. The control module controls the switch module to transmit the electric energy provided by the RTC power supply to the starting module by changing the signal value of the second IO signal after the preset time length, so that the data stored in the starting module is recovered to the initial data.
Optionally, before the control switch module stops transmitting the electric energy provided by the RTC power supply to the boot module, the control module controls the conversion module to stop converting the voltage provided by the external power supply into the working voltage of the boot module and providing the working voltage to the boot module, so that the boot module is turned off. And after the control module controls the switch module to continuously transmit the electric energy provided by the RTC power supply to the starting module, the control module controls the conversion module to continuously convert the voltage provided by the external power supply into the working voltage of the starting module and provide the working voltage to the starting module, so that the starting module is restarted. And after the restarting, the starting-up module sends a second power-on time sequence signal based on the initial data.
In another possible implementation manner, after the control module starts the boot module, if it is determined that the operating state of the boot module is normal according to the first power-on timing signal, the electronic device is started based on the first power-on timing signal.
In a possible implementation manner, before the electronic device is started based on the second power-on timing signal, the control module may determine, according to the second power-on timing signal, that the recovered operating state of the power-on module is normal.
Optionally, after the electronic device is started based on the recovered power-on timing sequence signal sent by the power-on module, the control module obtains a time parameter used for representing the current time from the power-on module, and configures the electronic device based on the time parameter, where the time parameter is obtained by the power-on module from an external clock module of the electronic device.
Specifically, the starting module reads a time parameter of the external clock module, which is used for representing the current time, and writes the time parameter into the data stored in the starting module.
The starting module can read the time parameter used for representing the current time by the external clock module through a Basic Input/Output System (BIOS), and write the time parameter into the data stored in the starting module, so that the electronic device can obtain the correct time parameter from the starting module.
According to the embodiment of the invention, the external clock module is added in the electronic equipment, so that after the data stored in the starting module is recovered to the initial data, the electronic equipment can acquire the time parameter for representing the current time from the added external clock module for configuration, thereby displaying correct real-time, and solving the problem that after the RTC power supply is interrupted to supply power to the starting module, the data stored in the starting module is recovered to the initial data, so that the real-time data stored in the starting module is also recovered to the initial set time data, thereby causing the error of the time displayed after the electronic equipment is configured based on the initial set time data.
In another possible implementation manner, after the control module receives a second power-on timing sequence signal sent by the power-on module according to the initial data, if it is determined that the recovered working state of the power-on module is abnormal according to the second power-on timing sequence signal, the control module performs an alarm prompt.
Specifically, the control module can control the alarm module to give an alarm through the first IO signal.
For better understanding of the embodiment of the present invention, a specific application scenario is given below, and a detailed description is given of a startup process of an electronic device by taking an example that an alarm module is enabled when a first IO signal is at a high level, a switch module is turned on when a second IO signal is at a low level, and a conversion module is enabled when a third IO signal is at a high level, as shown in fig. 3, which is a schematic diagram of the startup process of the electronic device.
S301, the control module sets the first IO signal sent to the alarm module low, sets the second IO signal sent to the switch module low, sets the third IO module sent to the conversion module low, and executes the step S302.
The alarm module does not give an alarm under the control of the low-level first IO signal, the switch module transmits the electric energy provided by the RTC power supply to the starting module under the control of the low-level second IO signal, and the conversion module stops converting the voltage provided by the external power supply into the working voltage of the starting module and provides the working voltage for the starting module under the control of the low-level third IO signal.
S302, the control module receives a starting instruction triggered by a user and executes the step S303.
And S303, the control module sets the third IO signal sent to the conversion module to be high, and S304 is executed.
The conversion module converts the voltage provided by the external power supply into a working voltage of the startup module under the control of the high-level third IO signal and provides the working voltage to the startup module, and when the voltage converted by the conversion module is stabilized at the working voltage of the startup module, the startup module is started.
S304, after the voltage of the converted electric energy is stabilized at the working voltage of the power-on module, the power-on module sends a first power-on timing signal to the control module, and step S305 is executed.
S305, the control module periodically detects whether the first power-on time sequence signal is at a high level; if yes, go to step S306; if not, go to step S307.
S306, the control module starts the electronic device based on the first power-on timing signal.
S307, the control module sets the third IO module sent to the conversion module low, and sets the second IO signal sent to the switch module high by delaying T1, and then executes step S308.
The conversion module stops converting the voltage provided by the external power supply into the working voltage of the startup module and provides the working voltage to the startup module under the control of the third IO signal of the low level, so that the startup module is closed. After a delay T1, the switch module stops transmitting the electric energy provided by the RTC power supply to the boot module under the control of the high-level second IO module, so that the data stored in the boot module is recovered to the initial data.
And S308, after the preset time length, the control module sets the second IO signal sent to the switch module to be low, sets the third IO module sent to the conversion module to be high by delaying T2, and executes the step S309.
The switching module continues to transmit the electric energy provided by the RTC power supply to the starting module under the control of the second IO module with low level, and after the time delay T2, the conversion module continues to convert the voltage provided by the external power supply into the working voltage of the starting module under the control of the third IO signal with high level and provides the working voltage for the starting module, so that the starting module works based on the initial data.
S309, after the voltage of the converted electric energy is stabilized at the working voltage of the startup module, the startup module sends a second power-on timing signal to the control module, and step S310 is executed.
S310, the control module periodically detects whether the second power-on time sequence signal is at a high level; if yes, go to step S312; if not, go to step S311.
S311, the control module sets the first IO signal sent to the alarm module to be high.
The alarm module carries out alarm prompt under the control of the first IO signal of high level.
And S312, the starting module reads the time parameter of the external clock module for representing the current time through the BIOS and writes the time parameter into the data stored in the starting module. The control module starts the electronic equipment based on the second power-on time sequence signal and acquires the time parameter from the starting module for configuration.
In the embodiment of the invention, when the control module determines that the working state of the starting module is abnormal, the data stored in the starting module is recovered to the initial data, so that the starting module sends the second power-on time sequence signal based on the initial data, and then the control module starts the electronic equipment based on the second power-on time sequence signal, thereby effectively solving the problem that the electronic equipment cannot be normally started due to the abnormal power-on time sequence signal sent to the electronic equipment by the south bridge chip caused by the abnormal stored data when the south bridge chip encounters an abnormal environment, improving the system performance of the electronic equipment and improving the use experience of a user.
