Embodiment Construction

[0040] The embedded system of the present invention automatically reads the application program files in the external storage device, and then copies the application program files to the internal storage device, and the internal storage device updates the application program. In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] After the embedded system is powered on, it first executes the system kernel program, which is mainly used to realize the necessary initialization of each functional module of the system, to detect various control signals during the startup process, and to guide the microcomputer according to the current operating status of the system. The controller executes a data copy program or application program. The system kernel program must be solidified into the sto...

Abstract

The invention relates to a method for updating application programs of an embedded system, which comprises detecting intervention operation, and if the detected intervention operation is the same as the preset intervention operation, updating the application programs. During the application program updating, the embedded system detects whether an internal interface device is connected with an external memory equipment, if yes, further determining whether the external memory equipment stores the application programs, the embedded system reads the application program files in the external memory equipment, copying the application program files to an internal memory device, which updates the application programs. Meanwhile, the invention also discloses an embedded system and a microcontroller. The invention can conveniently and flexibly update the application programs of the embedded system, and improve the maintainability of the equipment using the embedded system.

Description

technical field [0001] The invention relates to the field of embedded systems, in particular to an embedded system and a method for downloading application programs thereof. Background technique [0002] The internal program of the embedded system generally consists of two parts: the system kernel program and the application program. The system kernel program is mainly used to realize the initialization of each unit inside the embedded system; the application program is mainly used to realize various functions required by the embedded system. Under normal circumstances, the kernel program of the system remains basically the same, while the application program is different according to the functions that the embedded system needs to complete. The embedded system can first solidify the system kernel program to the internal storage space, and then solidify different application programs according to different functions. [0003] When maintaining and debugging a device with an...
