At present, a small number of users reflect the updated graphics driver, restart the computer, the screen resolution is very low, color quality is poor, and resolution can not be adjusted and so on (XP system). (veterans, please ignore them directly, novice small white seriously look at the reason: update the graphics driver, the updated driver file is not proper

Preface Device tree is a data structure used to describe hardware, similar to a plate-level description language, originating from OpenFirmware (of). In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation needs. But the plethora of platforms, the different hardware that led to

We open "Drive Wizard" software in the computer, the effect is as follows In the Open interface we just click on the second "driver" below Then you will automatically get all the drivers you want to upgrade. We click on "Upgrade" to start downloading the driver files. The driver will be installed automatically when the download is complete.

This document describes how to develop an I2C interface touch screen driver mounted on the friendly mini-2440 platform. Kernel edition linux-2.6.32.2,The platform is a touch screen with the arm9-s3c2440 + I2C interface. For exampleLinux I2C driver architectureDescriptionHttp://www.lupaworld.com/273398/viewspace-204237.html To mount a new I2C device, you need to implement three parts: 1) adapter hard

It took almost a week to learn drivers. During this period, I was busy learning Linux application programming, search driver, and kernel-related books for further study. In the previously friendly driver routines, the knowledge involved is very limited. It is imperative to study more driver source code and learn more about dr
