To NXP IMX6DQ Android Team：

    我们在IMX6Q Android 6.0上调试realtek的wifi 8188EUS模块，驱动已经加载，但是在进行无线连接的时候，出现以下错误

init: Starting service 'p2p_supplicant'...
init: Service 'p2p_supplicant' (pid 1132) exited with status 255

如果直接设置ifconfig wlan0 up ，wlan0可以挂载并且可以设置IP地址

如果ifconfig -a 可以看到wlan0 已经成功配置了IP地址，

但是p2p_supplicant 还是无法Init，出现上面的错误，请问这个问题应该会在什么引起的呢？

非常感谢！

Hello Linjin Meng,

    It seems that P2P service couldn't be normally started, you can refer to the porting steps described in the link, the engineer also use Realtek product.
