Embodiment Construction

[0019] see figure 2 As shown, it is the specification table of the flash memory planning of the present invention, and it can be clearly seen from the figure that the method for returning the boot system of the present invention is to first divide the flash memory planning in the device into four blocks, and the embedded Linux operating system ( The system boot tool (Boot Loader), Linux microkernel (Kernel), mini root file system (Mini Root File System), and user root file system (User Root File System) in Embedded Linux System are stored in In different blocks, set the blocks stored in the system boot loader (Boot Loader), Linux micro-kernel (Kernel) and Mini Root File System (MiniRoot File System) as read-only blocks, while the user root The blocks stored in the directory file system (User Root File System) are set as rewritable blocks, allowing users to write other applications (such as: JFFS2, EXT2 and EXT3, etc.) in the user root file system ( User Root File System), an...

Abstract

The recovery bootstrap system method comprises: dividing the flash memory of device with embedded Linux OS into four areas for the system guide tool, Linux micro-kernel, mini root directory system, and user root directory; setting the area with user directory as the erasable area and other areas as read-only areas; and arranging the detection program for user root directory in the mini file system to first detect the file and decide the log-in when starting.

Description

technical field [0001] The invention relates to a method for recovering a boot system, especially a method for enabling a device using an embedded Linux operating system to boot normally. Background technique [0002] According to the definition of the British Institute of Electrical Engineers, an embedded system (Embedded System) should be a device that controls, monitors or assists equipment, machines or even factory operations, and an embedded system is a system that combines computer software and hardware, and It can comply with the principle of "tailor-made", that is, a system developed based on a special purpose, and because the embedded system can improve product stability, portability, reduce product cost, and increase specific functions, etc., Therefore, it has been widely used. At present, common embedded operating systems include VxWORK, QNX, Palm OS, Windos CE, Linux, etc. Among them, the embedded Linux operating system (Embedded Linux System) has the advantage o...
