usb RNDIS方式下载NK.BIN

[ggj007]

各位老师好，我用的是devkit8500板子，它的eboot支持RNDIS下载NK.bin而不支持以太网下载。但下载过程串口打印信息如下：
Download file information:
-----------------------------------------------------------
[0]: Address=0x80002000 Length=0x01a9cb3c Save=0x80002000
-----------------------------------------------------------
Download file type: 1

...........................................................................................rom_offset=0x0.
..ImageStart = 0x80002000, ImageLength = 0x1A9CB3C, LaunchAddr = 0x80012218

Completed file(s):
-------------------------------------------------------------------------------
[0]: Address=0x80002000 Length=0x1A9CB3C Name="" Target=RAM
ROMHDR at Address 80002044h
Got EDBG_CMD_JUMPIMG
Got EDBG_CMD_CONFIG, flags:0x00000000

系统停在了这个地方。vs2005显示NK.bin已经完成下载，下载过程中也没有报错。下载的镜像是能通过sd或者nand方式启动。请问这问题出在哪个环节？

Target=RAM? eboot下载之前要目标设置为flash?

谢谢你的答复，下载之前是要设置eboot的，如设置thtp，ip，启动方式等。你说的target=ram是什么意思？能详细说一说吗？万分感谢！！！
