The openwrt 15.05 (git:// has updated the kernel version to 3.18.45 which will result in the compilation failure of the mtk-sdk-wifi due to the lack of file wifi_binary/mt_wifi.ko_3.18.45 and ./wifi_binary/mt_wifi.ko_3.18.45_all.

As workaround, I changed the git HEAD to the previous commit:

git checkout c170d84bbe08e0f049c99d3f376aae170a36458e -b pre_3_18_45

Although the workaround works, It would be desirable to add the new wifi_binary files to the repo.

I pull openwrt from origin master,

after update linkit feed,

cp 3.18.44 3.18.45
cp 3.18.44_all 3.18.45_all

then compile, will do the trick

Can you please build a binary wifi driver for kernel 3.18.45?

Also would it possible to build 4.4.x drivers to use with LEDE? There are a few of us that would like to experiment with LEDE on linkit7688.

Seemed like mtk-sdk-wifi is a closed source version driver. There's an open one in OpenWrt called mt76. Looks mt76 works for MT7688. I just ported LEDE 17.01 to 7688 but I don't have a device to verify now. If anybody wanna give it a try, take it.

I concur with @guanch1984, it seems that mt_wifi.ko_3.18.44 is binary compatible with the 3.18.45 kernel.
