参考文献：

嵌入式linux系统与主机通过串口传输文件

ubuntu 下minicom的安装及使用

操作系统：ubuntu10.04

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

到http://download.chinaunix.net/download/0007000/6293.shtml，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/

updating cache ./config.cache

creating ./config.status

creating Makefile

creating intl/Makefile

creating lib/Makefile

creating testsuite/Makefile

creating man/Makefile

creating po/Makefile.in

creating src/Makefile

creating debian/rules

creating Specfile

creating systype

creating src/lrzszbug

creating config.h

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                                                                         

�z 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。
