Embedded device and method for updating embedded software

Abstract

The present invention provides an embedded device and an update method for its embedded software. The device includes a memory card and a boot execution unit. The boot program is started, and the boot execution unit detects whether there is system software to be updated on the memory card. If there is, Then read the system software to be updated, and copy it to the storage area preset by the system software. The update method includes: starting a built-in boot program, detecting whether there is system software to be updated on the memory card, if there is system software to be updated, reading the system software to be updated, and copying it to the system software preset storage area. The method for updating the embedded device and its embedded software described in the present invention, by inserting a boot program in the embedded device, and storing the system software to be updated in the memory card of the embedded device, the user can Realize the update of embedded device software, which also brings great convenience to research and development, manufacturing and after-sales service.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an embedded device and an update method for its embedded software. Background technique [0002] For existing embedded devices, such as mobile phones, GPS, MP3 players, MP4 players, electronic dictionaries, handheld treasures, digital cameras, etc., the update of the embedded software must connect the device to a computer and operate on the computer. . The specific method is: use a dedicated data line to connect the embedded device and the computer, and then a tool program software in the computer will transmit the software to be updated to the embedded device through the data line, and generally store the updated software in the in the Flash memory of the embedded device. [0003] The above-mentioned method for updating the software is relatively complicated, and requires a dedicated data line, a computer, and a special tool program installed on the computer. It can be s...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned software update method is relatively complicated, and requires a dedicated data cable, a computer, and a special tool program installed on the computer. It can be seen that ordinary consumers cannot update the software by themselves.

And above-mentioned software update method, its update speed is very slow, also brings great inconvenience to research and development, manufacture, after-sales service
