1、下载iperf的源码，可以使用如下链接

iperf-2.0.5.tar.gz

2、编译

解压源码，切换到源码路径下，

export  PATH=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin:$PATH

./configure --host=arm-fsl-linux-gnueabi

make

3、将编译生成的iperf可执行文件拷贝到目标板/bin目录下

4、测试

root@freescale /$ iperf -c 192.168.2.178 -i 1 -t 60 -p 9999
