I have got the trunk from github .
And build it by myself.
But when I flash the image to the board, everything works well except wifi.
seems that the wifi driver do not support the mt7620n.
I have tried to put the wifi driver rt2860v2 to it, it can work.
I want to know that if the trunk support it, or just some configuration I need to enable.
Anyone can help for this issue.
You are aware, that wifi is disabled by default, right?
Thank for your answer, nozombian
Unfortunately， through the dmesg ,I found some error msg. eg:Invalid RF chipset
Since I'm outside now and,I can't show you my log,
