Abstract

The embodiment of the invention provides a bootstrap loader upgrading method and device, electronic equipment and a storage medium, and relates to the technical field of computers. A bootstrap loaderis installed in the electronic equipment, wherein the bootstrap loader comprises a first program and a second program, the first program is used for guiding the start of an operating system kernel ofthe electronic equipment and calling the second program, the second program is used for achieving other functions except for starting the operating system kernel. The method comprises the steps: whenthe first program or the operating system kernel is in a working state, if the bootstrap loader needs to be upgraded, obtaining an upgrading file of the second program; and upgrading the second program based on the upgrading file so as to upgrade the bootstrap loader. By applying the bootstrap loader upgrading scheme provided by the embodiment of the invention, the risk of upgrading the bootstraploader can be reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a boot loader upgrade method, device, electronic equipment and storage medium. Background technique [0002] Uboot (Universal Boot Loader, Universal Bootloader) is a boot loader mainly used in embedded systems, used to prepare the correct operating environment for the operating system before the operating system kernel runs, for example, initializing hardware devices, initializing memory, initializing clock, start the operating system kernel, etc. In addition, Uboot can also be used to start the boot screen, read USB (Universal Serial Bus, Universal Serial Bus) devices, download data, and so on. [0003] In the prior art, after the Uboot is installed on the electronic device, it is usually necessary to upgrade the Uboot installed in the electronic device. Since Uboot contains key programs that run the operating system kernel, once there is a problem in the upgrade p...
