Problems solved by technology

However, the boot loader of large and small systems has relatively high requirements for memory. The more comprehensive the functions of the smallest system, the more space it needs. For most embedded systems, storage space is very scarce. Various systems and users The space is compressed as much as possible; and if the minimum system needs to be upgraded, it may also have upgrade problems, resulting in complicated and inconvenient operations
[0007] To sum up, in the existing boot loader update scheme, there are still defects of complicated operation and inconvenient update

Abstract

The invention provides an updating method and device for a boot loader, and the method comprises the steps: sending a request message to a server, and requesting the new version information of the boot loader; receiving a reply message returned by the server, and obtaining new version information according to the reply message; and downloading a new version file of the boot loader from the serveraccording to the new version information and updating the new version file. According to the scheme, when the version is updated, a request message is sent to an external server by utilizing a hardware environment started by equipment; the new version information is acquired and the new version file is downloaded and updated, so that the updating operation complexity can be reduced, the autonomousoperation updating process of the equipment can be realized, the method is particularly suitable for an embedded operating system with enterprise-level layout, and the updating convenience is greatlyimproved.

Description

technical field [0001] This specification relates to the technical field of embedded operating systems, and in particular to a method and device for updating a boot loader. Background technique [0002] In an embedded operating system, a boot loader (BootLoader) is a program that runs before the operating system kernel runs. This program can initialize hardware devices and establish a memory space map, thereby bringing the system's hardware and software environment to a suitable state, so that Prepare the correct environment for the final call to the operating system kernel. Because in an embedded system, there is usually no firmware program like the BIOS, so the loading and starting task of the entire system is mainly completed by the boot loader. Common boot loaders include Redboot, ARMboot, and Uboot (Universal Boot Loader, an open source project that follows the terms of the GPL), among which Uboot is currently the most widely used open source boot loader. The bootload...
