TQ2440开发板烧录WinCE6.0后启动失败

开发板型号 TQ2440，64MB
下面是烧录步骤：
1、NOR启动 烧录 STEPLDR.nb1
2、烧录 eboot.nb0
3、烧录 LOGO图片Download LOGO Picture (.bin) to Nand  Flash
4、NAND启动  命令b
5、命令9，格式化
6、命令U，下载WinCE镜像
下载完成后，能够启动WinCE系统
关闭电源，再次上电启动，屏幕上显示LOGO图片
串口信息如下：

亲，根据你提供的信息来看，在nand坏块那个地方显示有很多连续坏块，我认为是你没有格式化Nand Flash引起的，一般情况出现大量的连续坏块都是假坏块，在uboot下载模式下使用命令9格式化一下就好了。
