请教wince5.0的启动问题，各位大侠多多指教啊

基于pxa270，定制wince的BSP，eboot已经跑起来了，内核也能下载了，但是内核启动到一半就卡住了，请教各位出现这种情况的可能原因是什么呢，搞了好几天了，头都大了。下面是DNW显示的信息：

2) Boot delay: 3 seconds
3) DHCP: (Disabled)
4) Reset to factory default configuration
5) Download new image at startup
6) Boot device order: SMSC -> PCMCIA0 -> PCMCIA1
7) Debug serial port: FFUART
D) Download image now

在此处就卡住了，请指教！

nand地址和nk大小有没有设对？

用的是norflash，地址应该没什么问题，nk.bin 22M左右，应该也没什么问题

這步過後, 最有可能是 driver 卡住

1. 將 driver 儘可能的移除, 若能啟動後, 再將 driver 一支支的加入.

2. 最好的方法, 請將 kitl 連上, 用 debug mode 去 build, 可能一次就能找出原因.


還是建議 lz 用第 2 個方法, 反正 eboot 都可以 download 了, 離 kitl 也僅是一步之遙了.

谢谢楼上，今天试一下，遇到问题还请多指教！

已经试验过了，去掉驱动只留串口，问题仍然没有解决，跑到这里后ethernet也断开了，不能KITL调试，会不会有可能是汇编代码部分有问题呢？
