Can't turn wifi on on latest AOSP image

Hi all,

I installed the latest images provided by the installation page and downloaded the image from [here].(http://builds.96boards.org/snapshots/hikey960/linaro/aosp-master/latest/hikey960-linaro--factory-.zip)

I followed the instructions in [here].(Linux Host Installation for HiKey960 - 96Boards)
I was able to install the AOSP and it is running on the board. However, for some reason when I try to enable wifi, it turn on then immediately turns off. In the serial output, the board shows me this every time the following message:

[  134.015239] init: Sending signal 9 to service 'wpa_supplicant' (pid 3566) process group...
[  134.020661] libprocessgroup: Successfully killed process cgroup uid 0 pid 3566 in 5ms
[  134.021514] init: Service 'wpa_supplicant' (pid 3566) received signal 9
[  134.046259] init: Received control message 'start' for 'wpa_supplicant' from pid: 2194 (/system/bin/wificond)

Does anyone have an idea how I can fix this?

Please note, if you use boot image boot-4.14.img.xz, then you should use vendor-4.14.img.xz; if use boot.img.xz (for 4.9 kernel), you need to use vendor.img.xz. Otherwise, it might have compability issue for WIFI.

If still can see issue, please report back, thanks.
