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： /************************************************/ U-Boot 2010.06 (Feb 28 2012 - 11:25:33)MPC83XX ?

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： ? 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： U-Boot 2010.06-00077-gd1e0776 (Dec 27 2011- 19:51:03) MPC83XX ?
