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?
