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 an Android device. This method is a method of use. It is used for the situation that the old module image has been burnt on the Android device, but the module on the Android device has been replaced with a new module. First, enter step S101 to The driver file (also known as the driver KO file) of the module (i.e. the new module) is stored in the driver code loading directory of the Android device, step S101 can be manually cut to the driver code loading directory by first putting the driver file into the memory card, 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 DebugBridge, which is a debug tool for Android. After the host computer (such as a computer) is connected to the ADB of the Android device, the host computer can execute co...

Abstract

The present invention provides a method and system for dynamically replacing module driver codes on an Android device, wherein the method includes the following steps: Step 10, storing the driver file of the module in the driver code loading directory of the Android device; Step 20, using a host computer Perform ADB connection with the Android device; Step 30, use ADB to execute the command to write the module name to the sysfs file system node; Step 40, restart the Android device. The invention greatly saves the debugging and running time after the replacement of the Android device module, and solves the problem of tediousness and low efficiency after the replacement of the existing Android device module.

Description

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