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))  --->
     Target Binary Format (ELF)  --->
     Target Architecture Variant (cortex-A9)  --->
 [*] Enable NEON SIMD extension support
 [*] Enable VFP extension support
     Target ABI (EABIhf)  --->
     Floating point strategy (VFPv3-D16)  --->
     ARM instruction set (ARM)  --->
