最近想在270上移植6.0，发现原来5.0的eboot不好用，重新改吧。改串口，改网络，下载打印信息如下：

2) Boot delay: 5 seconds

4) Reset to factory default configuration
5) RNDIS MAC address: 0-0-0-0-0-0
6) Launch existing flash resident image at startup
7) Boot device order: SMSC, USB RNDIS, PCMCIA0, PCMCIA1, USB SERIAL (DL Only)
8) Debug serial port: FFUART

L) Launch existing flash resident image now

到这应该是连接上了，但是下载没进度，卡住了，似乎是tftp的问题？
高人给点建议，谢了。
1.你的VS的下载配置有没有问题，有没有找到设备
2.是不是防火墙的问题，关掉试试
原来5.0的BOOT能跟你的电脑连吗，如果也不行，说明是你开发主机的问题。防火墙和杀毒软件尽量都不用。
另外，270下6.0和5.0的BOOT没什么区别的，为什么要改这么多内容呢？
回楼上，connectivity option中已经找到了minstn26197，关掉了防火墙，杀毒软件，依旧如此
270下5.0的eboot可以下载，但是不能引导6.0的内核，所以才重新改了6.0的eboot
设备的IP地址与开发主机在同一个网段吗？另外，你把MAC地址改为00-11-22-33-44-55试试看。我以前用270时发现有些MAC地址会导致网络不通。
原以为是PB5.0和6.0冲突，卸了5.0，依旧如此，怪了
另外问一下，6.0和5.0相比，多了5) RNDIS MAC address: 0-0-0-0-0-0这一项，在eboot中提示Microsoft Windows CE Ethernet Bootloader 1.22 for the Intel MainstoneIII Development Platform Built Dec 11 2009
ERROR: CS8900AInit: Failed detect chip
会不会是这里的问题？
全班eboot信息如下：
