Abstract

The invention discloses an update method of an embedded dual system, comprising the following steps: step S1, receiving and parsing an update command in bootloader mode to obtain an update mode and an updated mirror image file; step S2, judging whether the update mode is a mirror image The overall file update mode, if so, enter step S3; if not, enter step S4; step S3, read the storage device partition information in the updated mirror image file and re-partition the storage device; step S4, the updated mirror image The part of the file corresponding to the updating mode is written into the partition corresponding to the updating mode in the storage device. The invention discloses an update system of an embedded dual system. The present invention updates any required part of the image or the entire image in a simple and flexible manner, and successfully solves the problem of complex operation and long time spent by technicians when updating the system image.

Description

technical field [0001] The present invention relates to an update method and system of an embedded dual system, in particular to a small program that runs before the bootloader (BootLoader is the operation of the operating system kernel. Through this small program, we can initialize hardware devices, build Memory space map, so as to bring the system's hardware and software environment to a suitable state, so as to prepare the correct environment for the final call to the operating system kernel.In embedded systems, there is usually no BIOS (basic input and output system) like Firmware program (note, some embedded CPUs will also embed a short startup program), so the loading and starting tasks of the entire system are completely completed by BootLoader. Background technique [0002] With the development of informatization, intelligence, and networking, embedded system technology has gained broad development space, and is currently widely used in network communications, consum...
