Problems solved by technology

However, if there is a system crash in batches, the FLASH on the routing road must be removed and reworked, which not only increases labor costs, but also wastes time. In the process of removing and welding the FLASH, it is easy to cause product scrapping and increase costs.
[0004] It can be seen that when the system cannot be started, the existing upgrade methods must rely on hardware conditions such as serial ports or burners as support, otherwise the upgrade cannot be completed, which is ver

Example Embodiment

[0020] In the router provided by the present invention, on the basis of the existing FLASH partition, a small partition is added to store the minimum operating system, which occupies a small storage space and can be completed without changing the existing hardware cost. In a preferred example, the minimum operating system can be set to only need to implement the function of upgrading the FLASH firmware. When the normal system crashes, the minimum operating system is started to upgrade the firmware, which does not increase the hardware cost, but can effectively improve the current inconvenience of upgrading.

[0021] Such as figure 2 As shown, the FLASH partition in the present invention includes four partitions: Bootloader (boot boot program, or boot loader) partition 10, Kernel (operating system kernel) and FS (root file system) partition 20, Minifs (minimal root File system) partition 40, Nvram (non-volatile random access memory) partition 30.

[0022] Such as image 3 As show...

Abstract

The invention relates to a partition method and a firmware upgrading method based on a minimum operating system. The FLASH partition of a router is made to have a starting bootstrap program partition, an operating system nucleus and root file system partition, a minimum root file system partition and a nonvolatile random access storage device partition. The minimum operating system is stored in the minimum root file system partition and used for being started to carry out firmware upgrading when system crash happens. Through the method, the firmware upgrading operation is convenient, the minimum operating system is developed based on an existing operating system, and hardware cost is saved.

Description

technical field [0001] The invention relates to the field of router equipment, in particular to a router and a partition and firmware upgrade method based on a minimal operating system. Background technique [0002] The FLASH partition of the current router is as follows: figure 1 As shown, it includes three partitions: Bootloader (bootloader, or boot loader), Kernel (operating system kernel) and FS (root file system), Nvram (non-volatile random access memory). [0003] A router usually has only one operating system. When the system boot image file in it is damaged or the file system cannot be mounted, the router cannot work normally. The only way to fix this problem is to update a good version of the software. There are two ways to update the software at present. The first method is to directly enter the Bootloader partition and upgrade through the serial port. This method is often used when debugging codes in the research and development stage. The required hardware fac...
