Embodiment Construction

[0026] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0027] see figure 1 as well as figure 2 , the present invention provides a method for the same firmware to be compatible with different devices. This method is used for devices with little difference, such as differences in hardware or software. The following steps are included: Step S101 reads the hardware identification mark. Different hardware can be distinguished by reading the hardware identification. In this embodiment, the hardware identification is stored in the storage module, such as a ROM or SD card, and the hardware identification at this time can be burned into the storage module by a burning tool; in some embodiments, the hardware identification can be Read from hardware devices, such as reading the IDs of these hardware ...

Abstract

The invention provides a method and device in compatibility with different equipment with the same firmware. The device includes the following modules: a hardware recognition and identification recording module used for recording hardware recognition identifications, a hardware recognition execution module used for reading the hardware recognition identifications and executing operation corresponding to the hardware recognition identifications, an inverse operation generation module used for generating a record of inverse operation of the executed operation, and a recovery module used for executing the inverse operation after a system upgrading function is activated. According to the method and device in compatibility with different equipment with the same firmware, due to the fact only one software package is needed in initialization or upgrading for different equipment, the high maintaining cost brought by the fact that different equipment has different software packages is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method and device for the same firmware to be compatible with different equipment. Background technique [0002] In the development process of electronic products, especially embedded system electronic products, there are more and more situations where the hardware is not much different and the software customization is different, that is, the same type of product has multiple derivative versions, resulting in different devices. Hardware differences include different LCD and TP, different keyboards (multilingual keyboards), different CODEC and WIFI modules, etc. Software differences include third-party customized differences, GMS package differences, etc. In this case, if each derivative version corresponds to a version of software, especially for products exported to different countries, different firmware needs to be maintained from product development, producti...
