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。

在U-Boot下面移植操作系统可以采取很多方式：U盘、SD卡、NFS、TFTP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PC机IP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 plaincopyprint?

tftp 2000000 u-boot.bin //将u-boot.bin加载到RAM中去
echo $filesize
protect off all //解除nor flash的保护
erase fe000000 fe09ffff //擦除相应的分区
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
cmp.b 2000000 fe000000 $filesize //下载完还应该验证一下
tftp 2000000 rootfs.ext2.gz.uboot
echo $filesize
protect off all
erase fe800000 feffffff
cp.b 2000000 fe800000 $filesize
cmp.b 2000000 fe800000 $filesize
tftp 2000000 mpc8309twr.dtb
echo $filesize
protect off all
erase fe0e0000 fe0fffff
cp.b 2000000 fe0e0000 $filesize
cmp.b 2000000 fe0e0000 $filesize
tftp 2000000 mpc8309twr/uImage
echo $filesize
protect off all
erase fe100000 fe3fffff
cp.b 2000000 fe100000 $filesize
cmp.b 2000000 fe100000 $filesize
protect on all //对nor flash写保护
saveenv

最后重启就可以了。

接下来就会出现下面神气的现象：
