阿新 • • 發佈：2019-01-03
特此宣告我是轉載的，紅字部分為我新增的。
安裝配置minicom並實現通過minicom傳輸檔案
嵌入式linux系統與主機通過串列埠傳輸檔案
ubuntu 下minicom的安裝及使用
作業系統：ubuntu10.04
交叉編譯器：arm-linux-gcc-4.1.1
一、安裝配置minicom
1、安裝minicom
[email protected]:~$ sudo apt－get install minicom
2、配置minicom
[email protected]:~$ sudo minicom -s
出現這樣的配置介面：
+-----[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 |
+--------------------------+
選擇Serial port setup, 會看到這樣的選項：
+-----------------------------------------------------------------------+
| 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? |
+-----------------------------------------------------------------------+
輸入前面對應的字母即可進入相應的選項。將選項A的值設定為/dev/ttyS0 表示是串列埠1,將選項E的值設定為115200,將選項F設定為NO（請根據實際情況配置）.
設定預設上傳/下載的目錄，選擇Filenames and paths , 會看到這樣的選項：
+-----------------------------------------------------------------------+
| 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：開發板傳送給pc的檔案將儲存在Download directory所設定的目錄中，而pc要下載到開發板的檔案儲存在Upload directory所設定的目錄中
設定完成後，選擇”Save setup as dfl”,儲存為預設設定.
然後選擇“Exit”,即可進入Minicom的主介面:
Welcome to minicom 2.4

其中，我們用CTRL-A s來發送檔案給開發板；而用CTRL-A r來接收開發板上的檔案
二、為pc安裝lrzsz
lrzsz is a unix communication package providing the XMODEM, YMODEM ZMODEM file transfer protocols.
三、交叉編譯lrzsz並下載到開發板上
1、下載lrzsz原始碼包
到http://download.chinaunix.net/download/0007000/6293.shtml，下一個lrzsz的tar包，
2、解壓縮後，到解壓目錄中執行./configure
[email protected]:~/arm$ tar -zxf lrzsz-0.12.20.tar.gz
[email protected]:~/arm$ cd lrzsz-0.12.20/
[email protected]:~/arm/lrzsz-0.12.20$ ./configure

3、修改Makefile
有三個Makefile需要修改，分別是~/arm/lrzsz-0.12.20/Makefile、~/arm/lrzsz-0.12.20/lib/Makefile、~/arm/lrzsz-0.12.20/src/Makefile
[email protected]:~/arm/lrzsz-0.12.20$ vi lib/Makefile
[email protected]:~/arm/lrzsz-0.12.20$ vi src/Makefile
這個地方不僅僅要修改這個三個資料夾裡的Makefile 其他資料夾裡的也要修改，切記！
將這三個Makefile中的所有gcc替代成你開發板所需要的交叉編譯器，如arm-linux-gcc即：
CC = gcc
CPP = gcc -E
都改成
CC = arm-linux-gcc
CPP = arm-linux-gcc -E
4、編譯
在lrzsz-0.12.20/src目錄下會生成兩個可執行檔案lsz、lrz（或者sz、rz），把它們下載到開發板linux系統的/bin目錄下。
[email protected]:~/arm/lrzsz-0.12.20$ cd src
[email protected]:~/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、測試
1、開發板-->PC機
在開發板上輸入 lsz filename,然後會出現一個傳輸介面，傳輸完成後可以在你設定的預設下載目錄Download directory裡找到這個檔案。
2、PC機-->開發板
在開發板上先進入/tmp 目錄，然後輸入lrz。
# cd /tmp
# lrz
?z waiting to receive.**B0100000023be50
按Ctrl-A,再按s,選擇zmoden，會出現一個選擇檔案的介面，選擇你要傳輸的檔案（按一下空格鍵選擇目錄，按兩下空格鍵進入目錄），回車後出現一個傳輸介面，傳輸完成後，便可以在開發板的/tmp目錄下找到這個檔案了。
