已经按照光盘说明安装 50-ftdi.rules ,可以在dev下面看到ttyUSB0.
连接到开发板,minicom打开后 ,串口没有任何显示。。。。 直接在有com口的台式机上连接开发板,是可以看见有输出显示的。 实验了OpenOCD 找到JTAG的,也可以telnet localhost 4444 进行操作。 |

你执行 lsu*** ,贴出来看看;
如果没有lsu***的命令,就执行: sudo echo hello > /dev/ttyUSB0 , sudo echo hello > /dev/ttyUSB1 , …… 看看OPENJTAG上有没有灯在闪? |
|
|
|
root@myBox:/# lsu***
root@myBox:/# echo hello > /dev/ttyUSB0 bash: /dev/ttyUSB0: No such device or address root@myBox:/# echo hello > /dev/ttyUSB1 bash: /dev/ttyUSB1: No such device or address root@myBox:/# :( |

root@myBox:/# lsu***
root@myBox:/# echo hello > /dev/ttyUSB0 bash: /dev/ttyUSB0: No such device or address root@myBox:/# echo hello > /dev/ttyUSB1 bash: /dev/ttyUSB1: No such device or address root@myBox:/# :( |

没有识别到啊,你是用vmware?

不是额。。
我是debian 5.0 内核 2.6.11 我没有添加那条50-ftdi的rule 自己下装的ftdi的驱动(这个根识别USB应该没关系吧)和libu***之类的, 现在只想识别USB设备了 OPENOCD设置之类的以后再说 所以只是驱动的话,根那个rule有关系么,还是说添加那个rule只是自动挂载USB设备的操作?不太明白文档中的自动加载驱动。这个u***设备的驱动还是操作系统本身就有的?额。。乱了 大大帮忙理一理吧。 |

南方大侠,我也遇到一样的情况了。在minicom和kermit中都无法显示,我的系统是fedora13的,前面的步骤都做了。
lsu***的输出是 Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 003: ID 1bcf:05c2 Sunplus Innovation Technology Inc. Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 004: ID 1457:5118 First International Computer, Inc. OpenMoko Neo1973 Debug board (V2+) Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 004: ID 05e3:0718 Genesys Logic, Inc. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub /dev中只有一个ttyUSB0,我也用echo hello > /dev/ttyUSB0命令试了,OPENJTAG的灯有闪的,请问这是什么问题?谢谢! |

echo hello > /dev/ttyUSB0,OPENJTAG的灯有闪的 : 这就表示正常。
只有一个ttyUSB0就可以了,以前有些系统有ttyUSB0、ttyUSB1,但是更多的系统只有ttyUSB0。是正常的。 |
