U-boot烧写失败

过程是这样的
烧写U-BOOT，成功
烧写内核 成功
烧写文件系统 好像是成功了，因为烧写的过程中没有出现有skip坏块的提示，我烧写的是256M那文件系统

结果 boot linux却引导不了，引导的过程中出现了教程中所说的“”把64烧成256的错误“”

按教程的要求，format nand flash ,以下是信息
[1] Nand scrub - really clean NAND erasing bad blocks (UNSAFE)
[2] Nand earse - clean NAND eraseing
[q] Return main Menu
Enter your selection: 1

NAND scrub: device 0 whole chip
Warning: scrub option will erase all factory set bad blocks!
         There is no reliable way to recover them.
         Use this command only for testing purposes if you
         are sure of what you are doing!

Really scrub this NAND flash? <y/N> : y
Erasing at 0xffe0000 -- 100% complete.
OK

再来烧写UBOOT，结果就这样了
Enter your selection: 1

NAND erase: device 0 offset 0x0, size 0x40000
Erasing at 0x20000 -- 100% complete.
OK

NAND write: device 0 offset 0x0, size 0x0


0 bytes written: OK
试了好几次，dnw 的进度条一直处于静止状态，我的XP还死机重启两次

你烧写的是什么文件？
Length of file is too big : -442503158 > 64085884
怎么会有这样的size?

怎么样查看板子是64M还是256M啊,我去看买的,不记得是哪一种的
另外,论坛有没有QQ群啊,QQ聊起来方便点,论坛不够即时

u-boot-1.1.6_Q35_20100601.bin
确定烧写的是这个

今天早上来又试了下，还是出现昨天的问题，还有个疑问，我启动板子怎么进入USB DOWN的模式啊，我启动后是这样的

又重新做了下

加这个QQ 1526107786， 看看你的操作步骤

嗯，应该和你的SDRAM 的容量或者Nand 的容量有关，可能你烧写错误。
