Embodiment Construction

[0026] See figure 1 As shown, the present invention will be described in detail below.

[0027] A method for dynamically replacing the module driver code on the Android device. This method is a usage method. It is used when the old module image has been burned on the Android device, but the module on the Android device has been replaced with a new module. The driver file (also known as the driver KO file) of the module (that is, the new module) is stored in the driver code loading directory of the Android device. In step S101, the driver file can be first placed in the memory card and then manually cut to the driver code loading directory. The preferred method is to use ADB to send and save the driver file to the driver code loading directory. The full name of ADB is Android Debug Bridge, which is a Debug tool for Android. After connecting with the ADB of the Android device through the upper computer (such as a computer), the upper computer can execute commands on the Android de...

Abstract

The invention provides a method and system for dynamically replacing driver codes of modules of an Android device. The method comprises the following steps that (10) driver files of the modules are stored in a driver code loading catalog of the Android device; (20) ADB connection is carried out between an upper computer and the Android device; (30) an ADB is used for executing an instruction that the names of the modules are written in a sysfs file system node; (40) the Android device is restarted. According to the method and system for dynamically replacing the driver codes of the modules of the Android device, the debugging and operation time of the Android device is greatly shortened after the modules of the Android device are replaced, and the problems that operation is tedious, and efficiency is low after modules of an existing Android device are replaced are solved.

Description

Technical field [0001] The present invention relates to the technical field of debugging of Android devices, in particular to a method and system for dynamically replacing module drive codes on Android devices. Background technique [0002] When factories and solution providers produce Android devices, they select various peripheral modules to produce machines in accordance with the layout circuit design requirements. The code of the Android system must be configured according to these peripheral modules, and then the system image must be compiled and programmed into the machine. If a certain batch of orders only need to replace a certain peripheral on the basis of the previous version, such as the most frequent replacement of the WIFI module on an Android device, then the code needs to be reconfigured and burned, which is time consuming Long and inefficient. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a method and ...
