烧写winCE

我烧写NK时，串口信息如下：
Enter your selection: u
Please send the Image through USB.

BL_IMAGE_TYPE_BIN


Download BIN file information:
-----------------------------------------------------
[0]: Base Address=0x80200000  Length=0x21c4a00
-----------------------------------------------------
rom_offset=0x0.
ImageStart = 0x80200000, ImageLength = 0x21C4A00, LaunchAddr = 0x80205EC0

Completed file(s):
-------------------------------------------------------------------------------

LastLogSector: Last log sector is: 0x1bc7f.

一直停在这里，不知道为啥

如果是从linux换成wince需要格式化nand，另外烧定nk时，需要用b->9->u才能下载
