After the userspace of the ARM equipment starts, the userspace of the ARM equipment is determined in the kernel The information of the reset signal be present, according to the information of the reset signal by the ARM equipment factory reset parameter.

Optionally, the replacement request signal is the low level input signal of reset registers.

Optionally, the ARM equipment, which receives, resets request signal, is specially：

The reset keys of ARM equipment described in user's long-press, so that the ARM equipment receives weight corresponding to the reset keys Put request signal.

Optionally, in the period of the reset keys of user's long-press ARM equipment, if the uboot start completions of ARM equipment, User discharges the reset keys of ARM equipment.

As shown from the above technical solution, the present invention, which proposes a kind of ARM equipment and restarted, recovers the method for configuration of dispatching from the factory, and passes through After ARM equipment receives and resets request signal, the information of the replacement request signal is stored in by the uboot of the ARM equipment In the kernel of the ARM equipment, the userspace of the ARM equipment determines the letter that the reset signal in the kernel be present Breath, according to the information of the reset signal by the ARM equipment factory reset parameter, it the method achieve and guide starting That is low level detection just is carried out to reset registers when uboot starts, thus, it is possible to solve in the prior art to catenet Equipment restart recovery dispatch from the factory configuration when, the problem of long-press reset key overlong times, this method greatly shortens long-press reset Time needed for key, enhance ease for use and operability.

Brief description of the drawings

Fig. 1 is the method schematic diagram that the ARM equipment mentioned of one embodiment of the invention restarts the configuration that recovers to dispatch from the factory；

Fig. 2 be the ARM equipment mentioned of one embodiment of the invention restart recovery dispatch from the factory configuration when the transmission signal of reset signals Figure.

Embodiment

Below in conjunction with the accompanying drawings, the embodiment of invention is further described.Following examples are only used for more clear Illustrate to Chu technical scheme, and can not be limited the scope of the invention with this.

Fig. 1 show a kind of ARM equipment present embodiments provided restart recover dispatch from the factory configuration method schematic diagram, such as Shown in Fig. 1, this method comprises the following steps：

101st, after ARM equipment receives and resets request signal, the uboot of the ARM equipment resets request letter by described Number information be stored in the kernel of the ARM equipment；

For example, the reset keys of ARM equipment described in user's long-press, so that the ARM equipment receives the reset Request signal is reset corresponding to key, the replacement request signal is the low level input signal of reset registers.

The reset keys of ARM equipment described in user's long-press, so that the ARM equipment receives weight corresponding to the reset keys Put request signal；In the period of the reset keys of user's long-press ARM equipment, if the uboot start completions of ARM equipment, user Discharge the reset keys of ARM equipment.

102nd, after the userspace of the ARM equipment starts, the userspace of the ARM equipment is determined in described The information of the reset signal in core be present, joined the ARM equipment factory reset according to the information of the reset signal Number.

According to the above method, the present invention is specifically described by way of example.When the present invention is by needing long-press reset keys Between long equipment illustrate, such as：ARM firewall boxs.

The start-up course for recovering to dispatch from the factory configuration is restarted to ARM firewall boxs below to illustrate, and the present invention will be used Method verified.

ARM firewall boxs, which start, is divided into three phases：

First stage, it then follows open source code project initiation stage (Universal BootLoader, the abbreviation of GPL clauses Uboot), uboot equivalent in windows systems basic input output system (Basic Input Output System, Abbreviation BIOS), the Bootloader in ARM equipment as embedded Linux kernel, system after reset signals are received, What is carried out at first is exactly that uboot starts.

Second stage, after uboot start completions, carry out linux kernel (referred to as：Kernel loading), whole system is built The file system and basic framework of system.

Phase III, carry out user-written subroutine (referred to as：Userspace startup), load-on module is configured, i.e., herein Stage according to the low and high level signal of reset registers, judges whether factory reset.

By the three above stage, generally, ARM equipment goes to judge reset in last userspace load phases Long-press signal, and to start to this stage time-consuming longer for equipment, generally requires 2-3 minutes, therefore, the operation of long-press reset keys Time just considerably increases.

Fig. 2 be show using ARM equipment of the present invention restart recover dispatch from the factory configuration method the transmission of reset signals signal Figure, recover the start-up course of configuration of dispatching from the factory as shown in Fig. 2 restarting based on above-mentioned ARM firewall boxs, the invention provides one kind The method that the reset operating times can be reduced.

201st, after ARM firewall boxs receive and reset request signal, the uboot of the ARM firewall boxs is by institute State in the kernel for the information deposit ARM firewall boxs for resetting request signal in i.e. kernel, kernel will reset and ask Signal extraction comes out, and preserves.

For example, the reset keys of ARM firewall boxs described in user's long-press, so that the ARM firewall boxs receive To request signal is reset corresponding to the reset keys, it is the low level input signal of reset registers to state and reset request signal.

The reset keys of ARM firewall boxs described in user's long-press so that the ARM firewall boxs receive it is described Request signal is reset corresponding to reset keys；In the period of the reset keys of user's long-press ARM firewall boxs, if ARM prevents fires The reset keys of the uboot start completions of wall equipment, then user's release ARM firewall boxs.

202nd, after the userspace of the ARM firewall boxs starts, the userspace of the ARM equipment is determined The information of the reset signal preserved in the kernel, it is according to the information of the reset signal that the ARM equipment is extensive Appear again factory's arrange parameter.

Using this method, the operating time of reset long-press can be greatly reduced, carry out perceiving reset long-press in uboot Signal operation can be controlled in the 5-10 seconds, is consistent with current general standard, and before in the userspace stages to reset Signal was perceived, it is necessary to long-press signal about 1-2 minutes, by the embodiment of the present invention, it is apparent that being reduced using this method While the operating time of reset long-press, its ease for use and accuracy also greatly improve.

Each embodiment described above is merely illustrative of the technical solution of the present invention, rather than its limitations；Although with reference to foregoing The present invention is described in detail each embodiment, it will be understood by those within the art that：It still can be to preceding State the technical scheme described in each embodiment to modify, either which part or all technical characteristic are equally replaced Change；And these modifications or replacement, the essence of appropriate technical solution is departed from the model of various embodiments of the present invention technical scheme Enclose.
