| 这是什么现象?我的开发板在上电后,redhat9的minicom窗口里会不定时输出开发板的一些信息,开发板和redhat9的连接状态是:串口+网口(已mount /opt/EmbedSky/root_nfs) 
 minicom状态如下:
 [root@EmbedSky /]# eth0: link up, 100Mbps, full-duplex, lpa 0xC5E1
 hub 1-0:1.0: connect-debounce failed, port 2 disabled     不定时自已跑出来
 hub 1-0:1.0: connect-debounce failed, port 2 disabled    但是不影响使用
 hub 1-0:1.0: connect-debounce failed, port 2 disabled    能解释下什么问题不?
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 hub 1-0:1.0: connect-debounce failed, port 2 disabled
 
 
 现象之二:
 我的开发板启动时,在串口的输出中会有如下提示
 |*** Warning - bad CRC or NAND, using default environment
 //就是这句,是不是NAND flash有问题?
