操作系统：Ubuntu 10.04
交叉编译器：arm-linux-gcc-4.1.1
一、安装配置minicom
1、安装minicom
lingd@ubuntu:~$ sudo apt－get install minicom
2、配置minicom
lingd@ubuntu:~$ sudo minicom -s
出现这样的配置界面：
+-----[configuration]------+
| Filenames and paths |
| File transfer protocols |
| Serial port setup |
| Modem and dialing |
| Screen and keyboard |
| Save setup as dfl |
| Save setup as.. |
| Exit |
| Exit from Minicom |
+--------------------------+
选择Serial port setup, 会看到这样的选项：
+-----------------------------------------------------------------------+
| A - Serial Device : /dev/ttyS0 |
| B - Lockfile Location : /var/lock |
| C - Callin Program : |
| D - Callout Program : |
| E - Bps/Par/Bits : 115200 8N1 |
| F - Hardware Flow Control : No |
| G - Software Flow Control : No |
| |
| Change which setting? |
+-----------------------------------------------------------------------+
输入前面对应的字母即可进入相应的选项。将选项A的值设置为/dev/ttyS0 表示是串口1,将选项E的值设置为115200,将选项F设置为NO（请根据实际情况配置）.
设置默认上传/下载的目录，选择Filenames and paths , 会看到这样的选项：
+-----------------------------------------------------------------------+
| A - Download directory : /home/lingd/arm/download |
| B - Upload directory : /home/lingd/arm/upload |
| C - Script directory : |
| D - Script program : runscript |
| E - Kermit program : |
| F - Logging options |
| |
| Change which setting? |
+-----------------------------------------------------------------------+
注意：开发板发送给pc的文件将保存在Download directory所设定的目录中，而pc要下载到开发板的文件保存在Upload directory所设定的目录中
设置完成后，选择”Save setup as dfl”,保存为默认设置.
然后选择“Exit”,即可进入Minicom的主界面:

二、为pc安装lrzsz
lrzsz is a unix communication package providing the XMODEM, YMODEM ZMODEM file transfer protocols.
lingd@ubuntu:~$ sudo apt-get install lrzsz
三、交叉编译lrzsz并下载到开发板上
1、下载lrzsz源码包
下一个lrzsz的tar包，
2、解压缩后，到解压目录中执行./configure
lingd@Ubuntu:~/arm$ tar -zxf lrzsz-0.12.20.tar.gz
lingd@ubuntu:~/arm$ cd lrzsz-0.12.20/
lingd@ubuntu:~/arm/lrzsz-0.12.20$ ./configure

3、修改Makefile
有三个Makefile需要修改，分别是~/arm/lrzsz-0.12.20/Makefile、~/arm/lrzsz-0.12.20/lib/Makefile、~/arm/lrzsz-0.12.20/src/Makefile
lingd@ubuntu:~/arm/lrzsz-0.12.20$ vi Makefile
lingd@ubuntu:~/arm/lrzsz-0.12.20$ vi lib/Makefile
lingd@ubuntu:~/arm/lrzsz-0.12.20$ vi src/Makefile
将这三个Makefile中的所有gcc替代成你开发板所需要的交叉编译器，如arm-linux-gcc
即：
CC = gcc
CPP = gcc -E
都改成
CC = arm-linux-gcc
CPP = arm-linux-gcc -E
4、编译
lingd@ubuntu:~/arm/lrzsz-0.12.20$ make
在lrzsz-0.12.20/src目录下会生成两个可执行文件lsz、lrz（或者sz、rz），把它们下载到开发板linux系统的/bin目录下。
lingd@ubuntu:~/arm/lrzsz-0.12.20$ cd src
lingd@ubuntu:~/arm/lrzsz-0.12.20/src$ ls
ansi2knr.1 lrz lsyslog.o Makefile.in tcp.o zm.o
ansi2knr.c lrz.c lsz protname.c timing.c zmodem.h
canit.c lrz.o lsz.c protname.o timing.h zperr.c
canit.o lrzszbug lsz.o rbsb.c timing.o zperr.o
crctab.c lrzszbug.in Makefile rbsb.o zglobal.h zreadline.c
crctab.o lsyslog.c Makefile.am tcp.c zm.c zreadline.o
四、测试
1、开发板-->PC机
在开发板上输入 lsz filename,然后会出现一个传输界面，传输完成后可以在你设置的默认下载目录Download directory里找到这个文件。
2、PC机-->开发板
在开发板上先进入/tmp 目录，然后输入lrz。
# cd /tmp
# lrz
lz waiting to receive.**B0100000023be50
按Ctrl-A,再按s,选择zmoden，会出现一个选择文件的界面，选择你要传输的文件（按一下空格键选择目录，按两下空格键进入目录），回车后出现一个传输界面，传输完成后，便可以在开发板的/tmp目录下找到这个文件了。
