Because of the limited number of I/O ports of the main control chip of the all-in-one machine, there is often insufficient I/O ports to provide power supply or reset control for all these adapter boards or peripherals. When the whole machine of the all-in-one machine is restarted, the switching small plate or the peripheral which is not controlled by power supply cannot be powered off and is not reset, and the running state of the small plate is not initialized normally, so that the function of the all-in-one machine is abnormal. For example, if the HDMI OUT platelet is not powered off and restarted, the display is abnormal, and the touch frame can keep some previous states without resetting because of no power off and restart, so that the touch function is abnormal.
In order to solve the problem of abnormal functions caused by the fact that an external adapter plate or a peripheral which is not subjected to power supply control by an all-in-one machine main control chip is not reset or is not powered off and restarted under the restarting scene of the all-in-one machine, one solution is that the all-in-one machine main control chip usually needs to be additionally provided with power supply control or reset control on hardware design. However, because there are many peripheral small boards on the integrated machine, and the I/O provided by the actual master chip is limited, it may happen that some peripherals are not available with power or reset control I/O. Another solution is to add an I/O expansion chip. But this would increase the hardware cost accordingly.

Detailed Description
The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
The embodiments of the present disclosure are described below with specific examples, and other advantages and effects of the present disclosure will be readily apparent to those skilled in the art from the disclosure in the specification. It is to be understood that the described embodiments are merely illustrative of some, and not restrictive, of the embodiments of the disclosure. The disclosure may be embodied or carried out in various other specific embodiments, and various modifications and changes may be made in the details within the description without departing from the spirit of the disclosure. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Example one
The all-in-one machine is internally provided with a PM (Power manager) module which supports functions such as key awakening, network awakening, signal awakening, serial port instruction awakening, timing awakening and the like. After the integrated machine is started or restarted, the PM management module can control the integrated machine to enter a standby state and a low-power-consumption running state firstly, and receives various awakening detections.
After the integrated machine enters a Standby state, only 5V Standby is supplied with power, and only the program of the MCU of the PM module runs on software. The other parts are powered off. Therefore, if the connection is to be disconnected by using the mainboard for power supply, the standby state can be entered for a certain time, so as to achieve the purpose of power failure.
Specifically, the reset control method of the all-in-one switching equipment comprises the following steps:
The all-in-one machine needs to be restarted under the following several scenes: and (4) restarting a program under the android system, restarting the firmware after upgrading the program, upgrading the Recovery, or restarting the firmware after factory restoration. According to the prior art, in the restarting process of the all-in-one machine, the default state is that all power supply modules of the mainboard are not powered down, namely the power supply of the peripheral or the adapter board from the mainboard is continuous all the time. The existing integrated machine restarting process comprises the following steps: performing a reboot; entering a boot; entering kernel (real-time operating system); and entering an android system.
In the present invention, the reboot power down flag (reboot _ powerdown) may be set to 0 or 1, and in this embodiment, when the reboot power down flag is set to 1, it indicates that the standby mode is to be entered. The power down reset flag may be set to 0, indicating that the standby mode is to be entered. The specific setting value of the restart power-down flag should not be taken as a limitation to the present invention. For convenience of description, the case where the power down reset flag is 1 indicates that the standby mode is to be entered is described as an example.
The switching equipment comprises the peripheral equipment of the all-in-one machine, an external switching board and the like.
And 2, calling a restart mode (rebot), entering a boot phase (boot), and checking the start mode (boot mode). If the power-on standby mode is adopted, entering a standby state; if the Recovery mode is the Recovery mode, the restart mode is called again after Recovery is executed; if the normal restart mode is adopted, go to step 3.
And 3, powering off all hardware modules and continuing for a set time.
Specifically, in a preferred embodiment of the present application, step 3 specifically includes:
step 301, determining whether the power failure flag is a set value, and if so, entering step 302; otherwise go directly to step 4.
And step 302, after all the hardware modules are powered off and stay for a set time, the PM module wakes up the main control chip, exits from the standby mode and powers on the hardware modules.
All the hardware modules comprise hardware modules connected with the main control chip, and switching equipment such as peripherals, switching cards and the like which are not connected with the main control chip. All hardware modules can be powered off by enabling the PM module operated by the all-in-one machine to enter a standby mode. The set time period can be set according to actual needs, and the time length of the set time period is enough to completely power down all hardware modules and switching equipment.
And 4, starting a kernel (kernel).
And 5, starting the android system.
The normal restart mode is entered after the restart in default, and the standby state (power-down of each module) may be entered only in the power-up standby mode. In order to ensure that the hardware modules, in particular the peripheral adapter platelets, can be reinitialized. Under the condition of no reset and power supply control, the set time is long enough to wake up the relevant modules after the complete power failure, and the restart power failure mark is cleared. And the PM module automatically wakes up when the timing time is up. Then go to the normal starting process.
Executing a restarting flow in android operation:
(1) executing the rebot, and setting a rebot power-down flag, such as rebot _ powerdown ═ 1
(2) Entering a boot, performing boot check,
(3) if the reboot _ powerdown is equal to 1, setting a timing standby function, entering a standby mode, exiting the standby mode overtime, and awakening the main control chip by the PM module; if reboot _ powerdown is not equal to 1, kernel is started.
And (3) restarting the firmware upgrading program after upgrading is completed:
(1) before the upgrade program executes the reboot, setting the reboot _ powerdown as 1;
(2) entering a boot, and performing boot check;
(3) if the reboot _ powerdown is equal to 1, setting a timing standby function, entering the PM, exiting the PM after time out, and awakening the main control chip; if reboot _ powerdown is not equal to 1, kernel is started.
Restarting after Recovery execution:
(1) before executing rebot, set rebot _ powerdown to 1
(2) Entering a boot, performing boot check,
(3) if the reboot _ powerdown is equal to 1, setting a timing standby function, entering the PM, exiting the PM after time out, and awakening the main control chip; if reboot _ powerdown is not equal to 1, kernel is started.
The reset control method of the all-in-one switching equipment can solve the problem that a universal method for resetting the peripheral switching board in a power-off mode can be realized by powering down the mainboard in a software mode when the all-in-one machine is restarted under the conditions that a special extended I/O chip is not added and the hardware design of the mainboard is not modified. The method is suitable for all peripherals or switching small boards which are connected to the mainboard and are powered through the mainboard.
The invention also provides a reset control device of the all-in-one switching equipment, which comprises a main control chip, a PM module and the switching equipment, wherein:
and the main control chip controls the power supply or reset of the hardware module in the all-in-one machine.
The PM module runs when the all-in-one machine is in a standby state, and all unnecessary power supplies can be shut down in the standby state; when the integrated machine is restarted, a flag is set, a power failure mode is detected in a starting mode of a boot stage, and a PM module is operated to enter a standby mode; the power supply of the hardware module and the switching equipment is disconnected; the PM module wakes up the main control chip when the timing time is up.
The switching equipment is a peripheral of the all-in-one machine or is externally connected with a switching board, and the auxiliary function of the all-in-one machine is achieved. After the PM module is operated by the all-in-one machine, the switching equipment is powered off, the PM wakes up the main control chip after the power-off setting time is continued, and the switching equipment is powered on again.
Example two
Specifically, the reset control method of the all-in-one switching equipment comprises the following steps:
In the present invention, the power-down flag (boot _ powerdown) may be set to 0 or 1, and in this embodiment, when the power-down flag is set to 1, it indicates that the standby mode is to be entered. The standby mode may be entered when the power-down flag is set to 0. The setting value of the specific power-down flag should not be taken as a limitation to the present invention. For convenience of description, the case where the power-down flag is 1 indicates that the standby mode is to be entered is described herein as an example.
And 2, entering a boot stage (boot), confirming whether the power-down flag is a set value, if not, confirming a starting mode (boot mode), and if so, turning to the step 3.
And 3, clearing the set value of the power failure flag, awakening the main control chip by the PM module after all hardware modules are powered off and continue for a set time, exiting the standby mode and powering on the hardware modules.
And 4, entering a normal starting mode.
