Description: BSP 用于初始化硬件、引导操作系统并提供软件和硬件之间的设备驱动接口。针对某类
体系结构的处理器开发 BSP 时，了解其基本的体系结构和指令系统是必要的。总地来说，V
xWorks的启动过程凝练而精悍，流程清晰，各模块之间的耦合度很低。
VxWorks 和Linux 设备驱动的结构都相当复杂。 假设一个系统没有操作系统， 这个时候，
我们编写设备驱动的工作就完全停留在“驱使硬件行动”的层次上。然而，在 VxWorks 和 L
inux 系统中整合设备驱动，则不仅仅意味着“驱使硬件行动” ，还意味着更加丰富的内涵。
除字符设备驱动相对简单以外，VxWorks 和 Linux 对串口、USB 设备、块设备、网络设备
等都定义了一套非常复杂的驱动程序框架结构，因此，除了控制硬件，工程师不得不领悟操
作系统本身对设备驱动设定的套路，这往往需要一个非常痛苦地学习历程。 -BSP for the hardware, boot the operating system and provide software and hardware interfaces between the device driver. For certain types of
BSP processor architecture development, the understanding of its basic architecture and instruction is necessary. In general terms, V
xWorks concise and lean startup process, process definition, the coupling between the modules is very low.
VxWorks and Linux device drivers are quite complex structure. Suppose a system is not operating system, this time,
We are working on writing device drivers completely stuck in the "drive hardware action" level. However, in VxWorks, and L
inux system integration device driver, then not only means "to drive the hardware action", also means a richer meaning.
In addition to other relatively simple character device driver, VxWorks and Linux on the serial port, USB devices, block devices, network equipment
And so defines the driver of a very complex framework, therefore, in addition to control hardware, engine Platform: |
