Abstract

The invention discloses a system upgrading method and an embedded system, and belongs to the technical field of embedded type systems. The system upgrading method comprises: step S1, carrying out initialization operation on a preset button in the embedded type system by adopting a configuration loading unit arranged in the embedded type system; step S2, judging whether the preset button is in a pressed-down state or not, and shifting to step S3 when the preset button is judged to be in the pressed-down state; step S3, unloading a preset system upgrading file from an external server by adopting the configuration loading unit; and step S4, upgrading the embedded type system by adopting the system upgrading file, starting the embedded type system, and then exiting the embedded type system. According to the technical scheme, the system upgrading method has the beneficial effects that: the problem that system upgrading only can be carried out after the embedded type system is started in the prior art is solved; related workload of system upgrading is reduced; the stability of a system upgrading process is guaranteed; and the system upgrading process is simplified.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a system upgrading method and an embedded system. Background technique [0002] In the prior art, if an embedded system needs to be upgraded, it usually needs to be performed after the system is started. For example, some home routers are upgraded by connecting to a web server. In this kind of upgrade process, if there is an unexpected situation and forced to stop when burning the upgrade file to the flash memory (Flash) partition, it may cause damage to the system area, and in more serious cases, it may cause the system to fail to operate normally . Even in the factory, when the system version is updated due to heavy industry, it is necessary to input commands through the serial port to upgrade the system version, which will increase the workload of the system upgrade. Contents of the invention [0003] According to the existing problems in the prior art, a system u...
