Problems solved by technology

When the loader has a BUG or does not match the front-end equipment, it must be repaired through the self-upgrade of the loader module. However, when the loader is upgrading itself, once an accident occurs, the installation will fail, and the loader will not run normally. Unable to upgrade firmware
[0003] Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed

Abstract

The invention provides an intelligent display terminal firmware updating method. The firmware updating method includes the steps that two loading programs are set, and a terminal is guided and started through the different loading programs according to the current state of the terminal; the integrity of updating files is checked; the updating files are added with digital signatures; automatic updating and manual updating are selected alternatively to finish updating. According to the intelligent display terminal firmware updating method, the failure rate of the intelligent display terminal is reduced, and correctness of the updating files and security of updating are ensured.

Description

technical field [0001] The invention relates to program upgrades, in particular to an update method for an intelligent display terminal. Background technique [0002] With the wide application of intelligent systems and the rapid development of digital TV technology, digital TV intelligent display terminals based on intelligent systems have emerged as the times require. As an emerging smart terminal device, firmware plays a very important role in it. Due to the continuous expansion of the functions of the intelligent display terminal, and the continuous updating of the internal firmware and the loading program itself, the demand for firmware upgrade of the intelligent display terminal has become increasingly urgent. At present, most of the intelligent display terminal loader modules are based on the Linux platform, and few are based on the intelligent platform, and there are still great disadvantages. When the loader has a bug or does not match the front-end equipment, it ...
