配置单板架构
Target options ---> 目标板的配置
Target Architecture：目标架构，这里选择 ARM(little endian)，ARM小端模式 Target Binary Format：二进制格式，为 ELF Target Architecture Variant：架构变体为 arm920t，内核类型 Target ABI：应用程序二进制接口，为EABI Floating point strategy：浮点数的策略，选择为 Soft float ARM instruction set：arm 汇编指令集，选择 ARM
cortex-A8配置
Target Architecture (ARM (little endian)) ---> Target Binary Format (ELF) ---> Target Architecture Variant (cortex-A8) ---> Target ABI (EABIhf) ---> Floating point strategy (VFPv3-D16) ---> ARM instruction set (ARM) --->
cortex-A9配置
Target Architecture (ARM (little endian)) --->
