Problems solved by technology

[0005] However, in the prior art, if the above-mentioned memory with sleep function is used, after the system wakes up from a low-power consumption state, the system will hang up. After the system hangs up, the system interface will freeze, and the window cannot be refreshed or switched. All applications Affected, possibly resulting in data loss

Embodiment 1

[0054] In Example 1, including the above figure 1All steps of the method shown, where, as image 3 As shown, step S100 is realized through the following steps:

[0055] Step S101, when it is determined that the system enters the waiting state, generate a wake-up signal according to the preset sleep sequence of the memory 4;

[0056] Step S102, using the wake-up signal to wake up the memory 4 .

[0057] Exemplarily, in step S101, the working state of the system can be monitored by the monitoring device to determine whether the system enters the state to be started, for example, if it is detected that the system wakes up from a low power consumption state, it is determined that the system enters the state to be started . Certainly, the system wake-up success information may also be directly received from the wake-up module for waking up the system, and based on the information, it is determined that the system enters the ready-to-start state.

Embodiment 2

[0059] In Example 2, including figure 1 All the steps of the method shown, wherein, step S200 is specifically implemented through the following processing:

[0060] Sending a wakeup success signal to the control terminal of the processor 7, so that the control terminal sends a wakeup signal to the processor 7 in response to the wakeup success signal, so as to wake up the processor 7.

[0061] The control terminal of the processor 7 sends a wake-up signal to the processor 7 after responding to the wake-up success signal, so that the processor 7 wakes up after the memory 4 wakes up, thereby ensuring that the processor 7 can be stored in the memory 4. Successfully read the system startup code, effectively preventing the system from hanging.

[0062] In this embodiment, the system startup code can be a boot code, and the memory 4 is a memory 4 with a dormancy function, for example, it can be dormant when the system enters a low power consumption state to reduce the power consumpt...

Embodiment 2

[0075] The device for preventing system hangup provided in this embodiment includes all the content in Product Embodiment 1, and will not be repeated here. Wherein, in this embodiment, the second wake-up module 3 is specifically configured to perform the following operations: when the memory 4 is woken up, send a wake-up success message to the control terminal (second controller 6) of the processor 7 signal, so that the control terminal sends a wake-up signal to the processor 7 to wake up the processor 7 in response to the wake-up success signal.

[0076] After the second controller 6 receives the wake-up success signal from the second wake-up module 3, it sends a processor 7 reset signal to trigger the processor 7, thereby waking up the processor 7 (that is to say, the second controller only After the second wake-up module 3 sends a wake-up success signal, the response process will be carried out), therefore, it can be guaranteed that the processor 7 will wake up after the me...

Abstract

The invention relates to a method and device for preventing a system from being hung up and a computer readable medium, and the method comprises the steps: sending a wake-up signal to a storage storing a system starting code under the condition that the system is determined to enter a to-be-started state, so as to wake up the storage; detecting whether the memory is awakened or not; and if the memory is awakened, awakening a processor for starting the system, so as to enable the processor to read the system starting code from the memory. The situation that the system is suspended after being awakened can be effectively prevented.

Description

technical field [0001] The invention relates to the field of system startup, in particular to a method, device, equipment and computer-readable medium for preventing system hang-up. Background technique [0002] The memory generally stores some power or clock calibration parameters, chip number, software code version, and special function enablement, etc., but in some cases, considering security issues, the system startup code will be placed in the memory. After the processor is started, the first The system startup code is read from memory and executed. The memory itself has power consumption. When the system is running, the power consumption of the memory does not account for a large proportion. However, in some low-power situations, such as when the system is in standby, its power consumption still needs to be considered, especially for batteries powered by batteries. powered system. [0003] Since the memory stores the calibration parameters of the power supply and the...
