tq6410-sdio wifi 无法动态分配ip

根据帖子http://armbbs.net/forum.php?mod=viewthread&tid=14602&highlight=wpa%2B%2Bwifi，执行命令：wpa_supplicant  -Dwext -iwlan0 -c/etc/wpa_supplicant.conf  -dd& 是成功的，但是执行动态分配IP就不行：udhcpc -b -i wlan0   代码截图如下：

静态分配IP是可以的，能够连接上外网，截图如下：

这到底什么情况啊，恳请遇到这种问题的同仁不吝赐教！

将开发板上/usr/share/udhcp目录改名为/usr/share/udhcpc 试试。

将开发板上/usr/share/udhcp目录改名为/usr/share/udhcpc 试试。

昨天已经改过了，还是不行，真是奇怪了。。。
我那个udhcpc版本 会不会有问题？   udhcpc (v1.18.5) started

-q啊，试试～ udhcpc -q -i wlan0
