十万火急！！！！板子坏了吗？？？？

今天上午用TQ2440测试《TQ2440开发板使用手册V1.0_20090808.pdf》中的5.1.3中设置并保存系统实时时钟试验，当修改好之后，机子死机了，然后重启（nandflash启动）后就停在这里不动了

我不知道怎么搞了，后来就按照手册上说明重新下载了u-boot linux内核，还有yaffs文件，后再重启，还是这样的问题停在这里了，后来重新下了好几次，依旧是这个问题，后来干脆把nandflash格式化，再重新下，问题出大了，如下所示：（前面还有一部分现实的内容没能整下来）

请问天嵌的专家们，这个是怎么回事？是你们板子问题吗？

建议你用uboot的命令9下面的命令1进行格式化。
然后在内核中出现大量坏块是有两个可能：
1、yaffs文件系统导致的假坏块或内核因为分区引起的假坏块；
2、可能是真正的坏块，这个可能性极低。
