It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Figure 1 The method for starting a remote boot system of the present disclosure is shown. In an embodiment of the present disclosure, the method is used in an electronic device, comprising:

[0022] Step S101, in response to receiving a startup instruction sent by a remote terminal after configuring the configuration information of the embedded operating system of the electronic device, starting the embedded operating system, the startup instruction including the configuration information, and the configuration information including system environment variables and corresponding values.

[0023] In this embodiment, the execution subject of the remote boot system startup method, that is, the electronic device, can receive a startup instruction from a remote terminal directly or through a relay device. The startup instruction is sent by the remote terminal after configuring the configuration information of the embedded operating system of the electronic device.

[0024] The operating system here can be various operating systems such as Linux system. The system environment variable can be at least one of the following: a first startup variable bootargs and a second startup variable bootcmd.

[0025] Step S102, extracting and parsing the configuration information, and updating the system environment variables of the embedded operating system to the values ​​according to the parsed configuration information.

[0026] In this embodiment, the electronic device receives the network data packet and parses the system environment variables and the corresponding values. Afterwards, the system environment variables of the embedded operating system can be updated to the above values.

[0027] Step S103, guiding the kernel of the embedded operating system to start, and completing the startup of the embedded operating system.

[0028] In this embodiment, the electronic device can guide the kernel to start up and finally complete the system startup process.

[0029] This embodiment provides a solution for remotely starting an operating system, which can modify the system environment variables of the operating system through a remote terminal, thereby realizing the startup of an embedded operating system.

[0030] In some optional implementations of any one of the embodiments of the present disclosure, the configuration information includes an IP address of a boot loader in the embedded operating system.

[0031] In these implementations, the content of the remote terminal configuration may include not only system environment variables, but also the IP address of the boot loader (U-Boot) in the embedded Linux system.

[0032] These implementations can accurately locate the boot loader corresponding to the IP address through the IP address of the boot loader, which helps to smoothly execute the boot loader subsequently.

[0033] Optionally, the extracting and parsing the configuration information, and updating the system environment variables of the embedded operating system to the value according to the parsed configuration information, includes: executing a boot loader corresponding to the IP address to extract and parse the configuration information, and updating the system environment variables of the embedded operating system to the value according to the parsed configuration information.

[0034] In these optional implementations, the electronic device may execute a boot loader corresponding to the IP address to extract and parse the configuration information. Afterwards, the electronic device may update the system environment variables of the embedded operating system to the values ​​in the configuration information according to the parsed configuration information.

[0035] These optional implementations can load the corresponding boot loader through the IP address, thereby starting the embedded operating system.

[0036] In some optional implementations of any embodiment of the present disclosure, guiding the kernel startup of the embedded operating system to complete the startup of the embedded operating system includes: restarting the electronic device; in response to the electronic device having been restarted, guiding the kernel startup of the embedded operating system to complete the startup of the embedded operating system.

[0037] In some optional implementations of any embodiment of the present disclosure, the operation mode of the remote terminal includes a web page, host computer software or an APP, and the remote terminal and the boot loader in the embedded operating system are in the same network segment and are communicatively connected.

[0038] In these optional implementations, the remote terminal operation mode includes web pages, host computer software or APP, etc. The above three configuration terminals must ensure that they are in the same network segment as the boot loader of the embedded Linux system and can perform normal network communication, which uses the User Datagram Protocol UDP.

[0039] The remote terminal and the boot loader in these implementations can be in the same network segment and be connected in communication to ensure remote booting of the operating system.

[0040] In some optional implementations of any embodiment of the present disclosure, there is a network response function in the boot loader, and the network response function is used to receive external network data from the remote terminal; the response to receiving the startup instruction sent by the remote terminal after configuring the configuration information of the embedded operating system of the electronic device includes: responding to receiving the startup instruction sent by the remote terminal after configuring the embedded operating system of the electronic device through the network response function.

[0041] In these optional implementations, a network response function is added to the main loop main_loop function of the boot loader. If a network data packet sent by an external PC is received during the process of waiting for an interrupt signal, it is parsed into a specified data format and modified to the value of the corresponding environment variable.

[0042] These implementations can run the main_loop function during the boot loader startup phase, call the built-in network response function, receive network packets, and parse environment variables and corresponding values ​​to solve the problem that the boot loader cannot receive network packets. Add key network response functions to the main_loop function of the boot loader, compile with the source code, and use it after burning once. It does not affect the normal function of the boot loader, does not require additional software installation, and is easy to use.

[0044] This embodiment provides a solution for remotely starting an operating system, which can modify the system environment variables of the operating system through a remote terminal, thereby realizing the startup of an embedded operating system.

[0045] Optionally, the method further includes: executing serial port login; the configuring the configuration information of the embedded operating system of the electronic device includes: if the serial port login is unable, configuring the configuration information of the embedded operating system of the electronic device.

[0046] The present invention can provide a method for booting an embedded Linux system through a remote terminal, including a remote configuration terminal, a communication network and an embedded Linux system, so as to modify U-Boot environment variables through remote terminal configuration and boot the embedded system when the serial port cannot be logged in.
