Porting AP6335 WIFI to Android4.4.2

chenli_2016 — Thu, 16 Jun 2016 06:23:24 GMT

NXP社区的工程师

您好，

我们这边用到一款i.MX6Q SABRE的开发板为参考板，制作定制了自己的产品板子，Android版本为4.4.2，只有wifi有改动，我们wifi用的是AMPAK 的AP6335芯片，移植的时候参考NXP社区分享的文档Porting BCM4330/BCM43362 WIFI to Android4.2.2，现在在android界面层可以设置wifi网络热点，但是扫描不到网络，logcat错误如下：

驱动可以起来，也可以配置ip，用wpa_cli也能扫描到网络，主要问题是在android界面层可以设置wifi网络热点，但是扫描不到网络
