Description
Technical Field
The invention relates to a quick upgrading method of an embedded system.
Background
Embedded systems are increasingly used in a wide range of applications, involving many aspects of human life, such as digital communications, information appliances, aerospace, industrial process control, and military electronics. The embedded technology is more and more closely related to the aspects of daily life of people, and the integration trend of consumer electronics, computers and communication is more and more obvious, so that the embedded technology is used as an important component in the field of computers.
The embedded system is based on computer technology and has available software and hardware, and is suitable for application system with strict function, reliability, cost, volume and power consumption constraints.
Embedded systems are generally composed of embedded software and hardware, and the software is tightly integrated with the hardware. The hardware takes an embedded microprocessor as a core, and integrates a memory and input and output equipment special for the system; the software comprises initialization codes and drivers, an embedded operating system, application programs and the like, and the software is organically combined together to form system-specific integrated software.
With the change of software and hardware technologies, embedded devices are continuously updated, so that the system needs to be upgraded conveniently and quickly. In the prior art, a conventional upgrading mode of an embedded system is as follows: the embedded device is connected to an external host (a computer, a notebook computer and the like) through a serial port, and a specific operation command is input on the external host through tool software to upgrade a system in the embedded device. The method is not only complex in operation and easy to make mistakes, but also needs very strong computer professional knowledge, thus being not beneficial to the batch upgrading of products, and once the upgrading fails, the system can not be started normally.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a method for rapidly upgrading an embedded system, which can rapidly replace and upgrade configuration files, and can rapidly restore the system after the upgrade fails, so that the system can be normally started after the upgrade fails.
The technical scheme provided by the invention is as follows:
a method for rapidly upgrading an embedded system, wherein a storage medium for starting the system is manufactured in advance when the embedded system leaves a factory: dividing a storage medium for system startup into five partitions (the size of each partition can be determined according to the size of a file stored in each partition), wherein the first partition is used for saving a factory original configuration file, the second partition is used for saving a system startup mark, the third partition is used for saving a configuration file currently running by a system, the fourth partition is used for storing a root file system, and the fifth partition is used for storing user applications and data;
the quick upgrading method of the embedded system comprises the following steps:
step 1, transmitting a configuration file for upgrading to a root file system of embedded equipment needing upgrading;
step 2, replacing the original configuration file in the third partition with the configuration file for upgrading;
step 3, restarting the system;
step 4, after the system is powered on, firstly judging whether a second partition is provided with a starting mark, and determining a system starting mode according to whether the second partition is provided with a system starting mark;
if the configuration file exists, the system is started by reading the original factory configuration file from the first partition, and the original factory configuration file of the first partition is copied to a third partition to cover the original configuration file, wherein the original configuration file is read from the third partition; if not, loading a configuration file from a third partition to start the system;
in the initial state, the second partition is not provided with a starting mark;
step 5, setting a system starting mark in the second partition;
step 6, judging whether the system is started successfully; if yes, clearing the starting mark in the second partition, and turning to the step 7; otherwise, turning to the step 3;
step 7, judging whether the upgrade is successful; if not, returning to the step 1 to upgrade again; otherwise, the upgrade is successful, and the process is finished.
After the system is started, the first three partitions are hidden for a common user, and only the last two partitions are displayed. The first three partitions relate to the configuration of the system, and a user cannot modify the system at will and only operates the third partition when upgrading; thereby ensuring the security of the system.
The configuration file for upgrading is transmitted to the file system of the embedded device needing upgrading through a common network.
The step 2 specifically comprises the following steps: first mount the third partition of the storage media to the root file system of the system (making it visible to the user); and then copying the configuration file used for upgrading in the root file system to the mounted third partition, covering the original configuration file, and unloading the mounted third partition.
Has the advantages that:
the method is simple, convenient, quick and reliable, does not need operators with professional computer knowledge, and is convenient for upgrading the system in batches. Even if the upgrade is failed accidentally, the system can restore the configuration file to the original factory configuration after restarting again, and the user can upgrade the configuration file again, so that the system is influenced by the minimum time and the minimum loss.
