请问要如何决解?? 要如何加大kernel那区的size?

用supervivi的part命令，删除不需要的分区，把空闲的空间并入kernel分区

Enter your selection: q

请问vivi、param、kernel、root    这4个分区那一个是不需要的分区?vivi和kernel和root应该都是需要的吧?

1. 如果param分区够，那就把它并入kenel分区，不需要做part save, DNW下载之前只会读取当前RAM里的分区表；
2. 你也可以调整root分区的大小，把一部分空间挪到kernel分区里。

我是在Nor flash开机的，按下q进Supervivi> 去修改
可是我已将kernel修改为kernel          :    0x00060000    0x00230000    0
root            :    0x00290000    0x03d9c000    0
已照你的第2点把root分区的大小，把一部分空间挪到kernel分区里
zImage也才2.09M (2,194,168)，为何下载还是会出现超出大小的讯息(Length of file is too big)呢?

另外提一下我的是64M的mini2440，照20090719手册去做的。

那恐怕就是NOR Flash里的supervivi里写死了内核大小最大不能超过2M了

Supervivi又没提供原始码，怎办?还有其它方法吗?? 还是大哥你能提供一个修改过的Supervivi的给小弟我，内存就照上面那样配置。

或是在make menuconfig中有没有可以拿掉的功能，让zImage变小下来?

抱歉，我和你一样没有Supervivi的源代码；
至于内核的大小的裁剪，恐怕只有靠你自己去掉你目前所用的内核配置中不需要的选项了，这应该不难。
