每次下载软件时都用了supervivi 的“f”项来格式化nandflash，现在有两块板子（mini2440）出现supervivi加载linux内核后，解压出错导致系统不能运行的情况，也就是说linux内核数据损坏了。是不是因为supervivi 的"f"选项对是否会把nandflash的坏区都擦掉，下载kernel的时候下到坏区去了？

f是整片擦除，一般不会损坏flash

另外，请尽量提供详细的串口信息，才有助于分析问题

补充串口信息，如下：  
?oad Image of Linux...Uncompressing Linux...

ran out of input data

-- System halted

这就是串口打印的所有信息

烧写时的信息呢？

烧写的时候是正常的，这是用了一段时间才出现问题的

烧写时的完整信息发来看看，我问了很多次了哦

不好意思，最近在忙着调tiny6410，现在把烤内核的信息补上，麻烦帮看一下，谢了！

只看出烧写内核时是正常的，是不是你烧写的内核本身就有问题呢？
