全志A20 android4.2.2 MT7601 wifi移植 问题

[fire_drangon]

硬件平台：全志A20
软件平台：android4.2.2
模块： MT7601 WIFI 模块

原来在驱动A13上面的驱动代码， 现在移植到了A20上面，驱动编译过了。
放到板子上面，没有看到加载的模块。
跟踪发现程序好像没有走到加载模块的部分就出错了。
wpa_supplicant也没有启起来

以下是我截取的关于wifi部分的log，大家能否帮忙看看是什么问题：

是不是发错版块了，

"原来在驱动A13上面的驱动代码， 现在移植到了A20上面，驱动编译过了。" <---可能没有移植好。问wifi 原厂要一个A20 上面的驱动, 再试试。

看来只能这样了。

我怀疑是wpa_supplicant 与平台相关的。 沉的好快啊。自己定一下

朋友，最后解决了吗？

楼主，搞定了吗？
