Problems solved by technology

[0004] However, there are following disadvantages in adopting the network interface to update the software under the LOADER program: On the one hand, under the LOADER program, the updated data files need to be packaged into mpeg-2 format code streams and played by a code stream player. Then complete the modulation through the QAM modulator, and up-convert to the specified frequency point
However, in the production line of mass production or maintenance of products, it is necessary to wait for the product to start normally before performing software update detection and update operations, which will inevitably prolong the software update time, seriously reduce production efficiency, and increase the cost of the production line

Embodiment Construction

[0032] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The present invention sets out from the point of view of solving the system software update of embedded products such as set-top boxes on the production line, and considers that these existing embedded products basically start the system from the BOOT program of the system, and the network transmission function is integrated in the BOOT program. It is proposed to update the software from the BOOT program of the system.

[0034] Specifically, software updates for products are implemented using the following process:

[0035] a. Trigger the software update during the operation of the BOOT program of the product to be updated;

[0036] b. Start the network protocol in the BOOT program, and obtain the software update file from the network server;

[0037] c. Burn the software update file to the designat...

Abstract

The invention discloses a software updating method, which comprises the following steps of: triggering software update in the operation process of a boot program of a product to be subjected to software update; starting a network protocol in the boot program, and acquiring a software update file from a network server; and burning the software update file to a specific position to finish the software update of the product to be subjected to software update. By the method, software is automatically updated in a network under the boot program of a system, updating efficiency is improved, the updating process is simplified, and updating cost is reduced.

Description

technical field [0001] The invention relates to embedded products, in particular to a software update method for embedded products. Background technique [0002] For embedded electronic products such as TV set-top boxes, the system program is divided into three parts: BOOT program, LOADER program and APP program. The BOOT program is mainly responsible for the initialization and guidance of the system, and is the first program executed after the system starts. The LOADER program is mainly used to upgrade the system. If the APP is abnormal or needs to be upgraded during the running of the BOOT program, it will enter this program to upgrade the system. The APP program is the main function program of the system, and each function of the system is realized in the APP. [0003] When upgrading and updating embedded products, three interface update methods can be used, namely serial port update, USB update and network update. Due to the slow update speed and inconvenient use of s...
