TQ2440开发板 3.5寸屏幕

我可以保证，烧写的是针对 256MB的NAND Flash的 image。
另外，手册也有提到，如果是256MB到1GB的NAND Flash，烧写的image是 64BM的话，是会出错的，而在烧写过程中，并没有报错，

我晚上可以再烧写一次，我会顺便将烧写的信息，而不仅仅是出错的打印信息都发上来

不过，看打印信息，是 CRC 有错，是不是说明，烧写过程没有问题，NAND Flash 也没有问题，而是linux的image ...

第一个建议是仔细看一下开发板的使用手册，就在光盘里面。
至于你的问题:1.bad block是因为之前烧写了win ce，你需要使用菜单中的【9】，再选子菜单1，格式化nand flash.
2.烧写方式不对，先从norflash启动，向nand flash烧写u_boot，之后可以从按步骤烧写内核，文件系统，logo。完成之后，把板子上的开关掰到nand，重启。内核和文件系统都要用256m的，不用我提醒。

不好意思， 我终于知道 哪里出问题了，

我在烧完 文件系统之后， 随后做了如下操作，导致 出错。其实下面这段在正常烧写中是不要做的

在文档中是 这样的描述
“Enter your selection: q
EmbedSky>nand write.yaffs 0x30000000 0x50000 0x3325c80        ; 手工再次输入烧写命令”

已经可以进入linux了，看见 界面了， 耽误 诸位，不好意思了，谢谢

亲，你看手册，不过你看得不仔细哦。手册里面写的那个手工输入命令有个前提条件，是为了验证烧写错误后会出现伪坏块。正常烧写步骤里面没有将用手动输入的烧写命令的。
下版在这个地方单独说明一下，以避免引起误解。
