小弟根据从论坛上下载的mini2440 linux移植开发指南 进行移植操作。。下载并更新了2010-2月的supervivi （最新的吧）。。。
问题：
1.指南说明最新supervivi可以容纳内核5M的。。但我从ftp上下载的linux包。。烧写里面的linux内核。是2.5m的。。提示文件太大。。请问怎么设置才可以实现容纳内核5M

USB host is connected. Waiting a download.
Length of file is too big : 2517028 > 2097152
Failed downloading file
2.根据指南上的移植步骤。在移植nand的那一节。。是编译出错的（我用的是Ubuntu8.10，gcc是友善提供的4.3.2。。内核源码从论坛ftp下的）
。。。后面我根据官网内核里面的mach—mini2440.c对应改了下头文件。。编译通过了。。内核也能起来。。
是不是说指南上的步骤是有失误么？编译出错的源码忘了保留
3.更改了 supervivi的linux启动参数。。还是挂载不了yaffs2文件系统。。我挂回2009年11月的root-qt-128m的也不行。。

还有一个疑问。。从内核配置菜单中的boot option里面内核支持的mini2440里面是看不到linux_cmd_line的信息的，是空的
。。。然而若是不使用官网本身支持的mach-2440.c。而是按指南上自己建立的。。那是不是需要填写boot option里面的
linux_cmd_line信息。。而且要跟supervivi里面的完全一致的、？？
ps:移植的操作除了nand的改了包含头文件。。其他都是根据指南上移植的。。
求助。。。
