TWR_MPC8309调试日志

--------By Moresung Chan , At 12:00 ,Sep 16,2012

 一、软硬件:

PC机操作系统:Microsoft Windows Server 2003 R2

开发板:TWR_MPC8309、网线、USB下载线、USB_TAP、光盘

工具软件:超级终端或者ZOC、Tftpd32

 

超级终端下载地址:http://digitizor.com/2009/08/29/install-winxp-hyperterminal-client-on-windows-vista-or-windows-7-free/  (windows XP系统自带有这个软件,其它系统需要自行下载)

Tftpd32软件下载地址:http://tftpd32.jounin.net/tftpd32_download.html

 二、步骤:

1.      刚买的开发板没有加载操作系统(见下图),因此需要自己移植操作系统。好消息是开发板已经固化了U-Boot,所以这样我们就可以在U-Boot下面进行移植。(参考文档:TWRMPC8309UM_rev1_20110720.pdf)

 

2.      用USB下载线将开发板和PC机连接起来,默认是上电就启动开发板的,这个时候打开超级终端,出现以下U-Boot调试信息:

/************************************************/

/************************************************/

如果按下3种启动方式都不能提示出现以上红色提示信息,那么表示没有操作系统或者说没有配置好操作系统地址。(一般来说是没有下载操作系统的原因)

 

3.      不用担心,U-Boot是个很好的工具,它的命令行模式已经非常接近linux下的shell了,而且功能也很强大,输入help命令可以查看它支持的命令:

4.      详细的介绍以及操作可以查看一下文档:

http://blog.csdn.net/ghostyu/article/details/6968681

5.   有了U-Boot的基本知识以后,我们就可以进行移植操作系统了。

U-Boot下面移植操作系统可以采取很多方式:U盘、SD卡、NFSTFTP等等都可以。开发板光盘里面提供了tftp方式移植的文档,那么我们就按照这个方式来移植操作系统吧。

1)用网线连接开发板和PC机(此时PC机要断网),然后设置PCIP地址(这个地址只需要和开发板的地址在一个网段就行了,可以不按照教程中的设置),然后就可以按照Info_tftpd32.pdf这个文档里面的操作进行设置。


2)这一步告诉你怎么通过tftp服务将PC机中的相应文件加载到开发板的nor flash当中去。

参考文档:TWR-MPC8309_Linux_BSP_User_Manual.pdf

里面有一段是这样的:


(由于我是直接将二进制文件放入TFTP_Root文件夹,所以下面的命令中不会有/mpc8309twr/目录)

我的目录如下:


看过U-Boot命令之后,相信对这个命令行模式的命令有了一定的了解吧。

3)这一步就可以按照顺序来加载文件了:

按照下面的分区地址来进行加载

下面贴上我的命令行模式的命令顺序:

 

[cpp] view plain copy print ?
  1. tftp 2000000 u-boot.bin   //将u-boot.bin加载到RAM中去  
  2. echo $filesize              
  3. protect off all           //解除nor flash的保护  
  4. erase fe000000 fe09ffff   //擦除相应的分区  
  5. cp.b 2000000 fe000000 $filesize  //将内存中0x2000000开始的内容复制到nor flash中相应的地址去  
  6. cmp.b 2000000 fe000000 $filesize //下载完 还应该验证一下  
  7.    
  8. tftp 2000000 rootfs.ext2.gz.uboot  
  9. echo $filesize  
  10. protect off all  
  11. erase fe800000 feffffff  
  12. cp.b 2000000 fe800000 $filesize  
  13. cmp.b 2000000 fe800000 $filesize  
  14.    
  15. tftp 2000000 mpc8309twr.dtb  
  16. echo $filesize  
  17. protect off all  
  18. erase fe0e0000 fe0fffff  
  19. cp.b 2000000 fe0e0000 $filesize  
  20. cmp.b 2000000 fe0e0000 $filesize  
  21.    
  22. tftp 2000000 mpc8309twr/uImage  
  23. echo $filesize  
  24. protect off all  
  25. erase fe100000 fe3fffff  
  26. cp.b 2000000 fe100000 $filesize  
  27. cmp.b 2000000 fe100000 $filesize  
  28.    
  29. protect on all      //对nor flash写保护  
  30. saveenv  


最后重启就可以了。

接下来就会出现下面神气的现象:
