系统每次启动的时候都有很多这样的打印，而且每一次开机都比上一次的多，
擦除nand重新烧写内核和文件系统恢复正常。
但是不能每次这恢复系统啊，这个问题要怎么解决呢？是什么原因引起的？
各位大哥帮帮忙啊，小弟万分感谢！

machoe · 发表于 2011-2-21 19:59:48

格式化一下，重新烧写，有可能是假坏块

machoe 非常感谢啊！格式化一下，重新烧写内核和文件系统就可以了！:)

格式化就行哟！命令9 是完全格式化了就有消除假坏块的功能

这个东西又出来了！我格式化之后这个本来没有了，但是下班回来一开机又出现这个了，，，怎么回来啊，不能每次都去把nand格式化啊，，这个问题的根本在哪里呢？

shufexiu · 发表于 2011-2-22 18:42:30

nand的驱动引起的
如果是2.6.30.4内核修改 “drivers/mtd/nand/s3c2410.c” 的大概第752行
如果是 2.6.25.8内核修改 "drivers/mtd/nand/s3c2410.c" 的大概669行
将 chip->ecc.mode = NAND_ECC_SOFT;
改成 chip->ecc.mode = NAND_ECC_NONE;
