大虾们，烧写winCE镜像时，为什么最后提示“Failed to load kernel region into RAM..

小弟用的是天嵌4.3寸屏，Nand Flash256M的开发板，,按照“天嵌配套光盘\TQ2440_CD\出厂烧录镜像合集\烧写方法.txt”，
wince烧写方法：
从nor启动进入uboot下载模式：开机-》选择1，烧写stepldr.nb1文件-》选择2，烧写eboot，-》
选择b，烧写logo文件，-》关机。
然后从nand启动进行烧写：开机的时候按住空格键，选择b，选择9，然后选择u，用DNW烧写NK文件。
等几分钟完成后会自动进入到WinCE系统，然后重启开发板即可正常使用。
烧写winCE镜像，为什么最后提示“Failed to load kernel region into RAM..,请大虾们帮忙分析一下原因，本人在此先谢过了。串口工具打印的信息具体如下：

到这一步我通过DNW工具，烧写wince6.0的“NK_Q43_3Serial_20100603.bin”，然后串口继续打印出如下信息：

补充个问题：我从NOR Flash启动后，选择9“Format the Nand Flash”，出现下面情况：
##### EmbedSky BIOS for SKY2440/TQ2440 #####

Really scrub this NAND flash? <y/N> :
y→Enter变成下面：
Really scrub this NAND flash? <y/N> : scrub aborted
感觉NAND flash并没有格式化，请问各位大侠还有什么办法才能将NAND flash进行格式化？

太长了，只看到最后一句‘请问各位大侠还有什么办法才能将NAND闪存进行格式化？’
用SecureCRT烧写软件选第9个就行了
[1] Download u-boot or STEPLDR.nb1 or other bootloader to Nand Flash
[2] Download Eboot (eboot.nb0) to Nand Flash
[3] Download Linux Kernel (zImage.bin) to Nand Flash
[5] Download CRAMFS image to Nand Flash
[6] Download YAFFS image (root.bin) to Nand Flash
[7] Download Program (uCOS-II or TQ2440_Test) to SDRAM and Run it
[8] Boot the system

我的比较顺利，没遇到过这种情况

我就是选择9然后回车，出现下面的情况：

谢谢你的回复！

问题已解决！
wince烧写方法：
从nor启动进入uboot下载模式：开机-》选择1，烧写stepldr.nb1文件-》选择2，烧写eboot，-》
选择b，烧写logo文件，-》关机。

然后从nand启动进行烧写：开机的时候按住空格键，选择b，选择9(注意：这一步进行两次，这是成功的关键所在)，然后选择u，用DNW烧写NK文件。
等几分钟完成后会自动进入到WinCE系统，然后重启开发板即可正常使用谢谢各位的积极响应！

呵呵 ，学习 。。、、

我的烧写玩给你的一个情况，按照这个选择9两次的方法还是不行哎，郁闷:(

我也遇到同样的情况了，烧写出厂带的镜像就没有问题，自己编译的就不行

选择9后显示屏就变成了上面一半是白屏！！！！而且选择U后，出现：

然后就没反应了，请问该怎么解决啊？

有可能是eboot的问题
