自己编译的Qtopia 更新制作文件系统出错

编译的Qtopia 更新制作文件系统时，把生成的my_qtopia.img通过USB下载到开发板，重新启动后报错“unable to open an initial console: ERR -2” ，我烧的是带鼠标的qtopia，不知是什么原因？------烧写光盘自带的“root_qtopia_mouse.img"能正常工作。

部分信息如下：

自己先顶一下

ERR: -2通常是"No such file"的意思。把完整的串口输出信息贴出来

问题解决了，呵呵
#cd /opt/FriendlyARM/QQ2440/root_qtopia_mouse
#tar xvzf ../arm-qtopia/target_qtopia.tgz (更新Qtopia 系统)
#tar xvzf ../arm-qtopia/target_konq.tgz (更新嵌入式浏览器)
#mkyaffsimage root_qtopia_mouse my_qtopia.img

root_qtopia_mouse是我新建的文件夹，里边没有根文件系统，先把root_default.tgz解压到该文件夹中就OK了。
