近年來嵌入式裝置所發展的速度超乎想像，並且提供愈來愈多樣式的功能及用途，嵌入式裝置開發的時間也隨之愈縮愈短，所以研發的流程也勢必加快，才能符合市場需求。當新的裝置標準出現後，驅動程式的開發及研究就變得更為重要，因此探討及理解Linux核心內的驅動程式是有助於開發應用程式在不同嵌入式裝置上。本論文針對Embedded Linux上影像裝置的驅動程式Video4Linux在 BeagleBoard-xM的硬體架構上。包含開發的完整過程、開發環境之建立、核心配置、驅動程式的移植、交叉編譯環境及伺服端和客戶端應用程式的開發環境等。依照此基礎來建立一個簡單透過網路的影像串流系統，遠端可利用V4L2的控制結構透過網路來控制伺服端影像模組的影像參數。

The development of embedded devices speeds up in recent years. They provide multiple functions and diverse utility in the technology field. Most of all, the progress of developing embedded devices should be quick for marketing demand. For the above reasons, how to develop the device driver become more and more important when a new device is introduced. Therefore, it is useful to explore the drivers of the Linux kernel for developing applications on various embedded devices. This study is about a Video4Linux device driver based on embedded Linux kernel with a BeagleBoard-xM hardware architecture. The content of the study includes complete development process, building environment, kernel configuration, drivers porting, and cross-compiler. According to the study, it can create a remote control application with V4L2 for video streaming systems.
