Abstract

An embodiment of the invention provides a Bootloader program module updating method and device, and relates to the technical field of embedded systems. The method includes the steps: updating a secondBootloader program module in two Bootloader program modules after determining that a first Bootloader program module in the two Bootloader program modules can successfully guide a network device to start; ensuring that the first Bootloader program module and the updated second Bootloader program module can successfully guide the network device to start. Updating is automatically realized withoutmanually paying close attention to the difference between the two Bootloader program modules, excessive version consistency or difference of the two Bootloader program modules is avoided, and the method is good in universality and high in reliability.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a method and device for updating a Bootloader program module. Background technique [0002] Most of the current embedded system equipment, in order to improve the reliability of the operating system startup, usually adopts a dual Bootloader program (system startup boot program) design, its role is: when one boot program fails, it is hoped that another boot program can continue System startup guide. The existing bootloader update scheme usually updates two Bootloader programs at the same time. After the system is restarted, if one bootloader cannot successfully boot the device, the other bootloader cannot successfully boot either, resulting in the failure of the device system to start. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a bootloader program module update method and device to improve the above problem...
