基于AT91RM9200的BOOT LOADER的开发与移植

Transplant and Development of Boot Loader Based on AT91RM9200

以ARM920T为内核的AT91RM9200是采用RISC(Reduced Instruction Set Computer,精简指令集计算机)架构的32位ARM(Advanced RISC Machines)微控制器,具有低功耗、高性能、执行速度快、执行效率高等特点。本文以AT91RM9200为平台,论述了bootloader文件的开发,并通过交叉编译和调试,完成了boot loader(即u-boot)文件的移植。

Because of ARM920T as the kernel ATglRM9200 are using RISC （Reduced Instruction Set Computer） construction, ARM （Advanced RISC Machines） of 32 bits Microcontroller take on low--loss and low-consume ,high capability, high executing speed. This paper use AT91RM9200 as a platform, achieve development of boot loader, and by debug and compile of this platform, achieve transptant of boot toader （u-boot） tastty.
