1：可以下载deb包，也可以下载tar.gz包，这里使用tar.gz，解压完后进行相关的设置即可使用。scratchbox-core-1.0.17-i386.tar.gzscratchbox-libs-1.0.17-i386.tar.gzscratchbox-devkit-cputransp-1.0.9-i386.tar.gzscratchbox-toolchain-arm-l

1: 下载Qemu源码编译，由于只需要arm的其他的就不编了./configure --target-list=arm-softmmu --prefix=xxxmake make install添加xxx/bin 到环境变量 运行 qemu-system-arm -M ?可以查看qemu支持的开发板，默认支持integratorcp.  2:配置内核,选

<br /><br />1. __attribute__ ((packed)) 的作用就是告诉编译器取消结构在编译过程中的优化对齐,按照实际占用字节数进行对齐，是GCC特有的语法。这个功能是跟操作系统没关系，跟编译器有关，gcc编译器不是紧凑模式的，我在windows下，用vc的编译器也不是紧凑的，用tc的编译器就是紧凑的。例如：<br />在TC下：struct my{ char ch; int a;} sizeof(int)=2;sizeof(my)=3;（紧凑模式）<br />在GCC下：struct
