Build LEDE

Serg Ivannikov

Good day.
I am try to build firware(lede) from sources https://github.com/OnionIoT/source.git
During compiling packet o2-wifi, error hapend
cp -fpR ./wifi_binary/mt_wifi.ko_4.4.74 /home/user/onion/onion_o/source/build_dir/target-mipsel_24kc_musl-1.1.16/linux-ramips_mt7688/o2-wifi-2015-06-01/ipkg-mipsel_24kc/o2-wifi/lib/modules/4.4.74/mt_wifi.ko
cp: cannot stat './wifi_binary/mt_wifi.ko_4.4.74': No such file or directory

When I try to build firmawe from lede sources v17.01.4 https://git.lede-project.org/source.git, I get the same error.
Where I can find this file(mt_wifi.ko)?
