Android集成lrzsz

为啥要移植lrzsz

本文中的lrzsz代码点击此处获取
Hikey开发板有两类USB口，两组USB-TypeA母口作为Host，可以接键盘、鼠标。另一组mini-USB母口，作为devices，可以接到电脑上调试。但目前这两种接口无法同时使用，即通过键盘鼠标操作时不能使用ADB。
虽然可以通过minicom或者putty之类的工具连接串口查看LOG、执行命令。但Android系统中缺少通过串口传输文件的工具，有文件传输需求的时候还需要插上ADB口，通过adb push/pull操作，不是太方便。

通过busybox的rx命令虽然可以接收文件，但无法将系统中的文件传输到主机上。而且rx只支持xmodem协议。一些新的工具如Xshell只能支持Zmodem协议。
lrzsz能够同时支持xmodem、ymodem以及zmodem协议，具备发送接收功能，能满足我们的需要。

交叉编译lrzsz

交叉编译分为以下几步：

1. 准备交叉编译链。

这里面使用的是arm-linux-gnueabihf-4.9。可以到Linaro的主页下载。将下载到的文件解压缩到/opt/目录，设置好环境变量。

[david@opt]$ cd arm-linux-gnueabihf-4.9/bin/
[david@bin]$ export PATH=`pwd`:$PATH
[david@bin]$ arm-linux-gnueabihf-gcc --version
arm-linux-gnueabihf-gcc (Linaro GCC 4.9-2015.01-3) 4.9.3 20150113 (prerelease)

2下载lrzsz源码
从官方主页下载lrzsz软件包 lrzsz-0.12.20.tar.gz 。解压缩。

[david@Code]$ tar -zxvf lrzsz-0.12.20.tar.gz

3./configure：
