| Because of the embedded system's outstanding characteristics of small size,high performance,low cost,high reliability and well practicality,it has been applied in many fields such as military,electronics,communication,industrial control etc.Embedded Linix is an operation system which is cut off and modified from common Linux,and which can run on embedded computer system.Since it has the advantages from both Linux and Embedded System,Embedded Linux has large market prospect.In this paper, the study is based on the AT91RM9200 embedded industrial controller.The ARM architecture are summarized and the resources of embedded industrial controller based on AT91RM9200 is introduced in the first.Then,give out start-up guide code(U-BOOT)and Linux kernel's start-up analysis,also porting them into the hardware platform and the basic system functions is achieved.Finally,the embedded linux driver development methods is introduced by an example of a AD module.Thus,the software environment of the embedded industry controller which will be used in control of wind power generator has been achieved. |
