Hi All,

I'm porting new wifi driver into openwrt with backports.
Insert wifi driver and use wpa_supplicant to control wifi chip, anything looks good.
But, once I put wireless config into /etc/config/wireless, wifi chip keep scanning and not working anymore. Looks following logs.

So, my question is how should I fix this issue? Please advise. Thanks.

This file is empty at the beginning? Normally there should be a default config for every detected wifi device.

Yes, default is empty. After I run "wifi config" , enable radio0 and set STA mode to connect my AP.
But wifi keep scanning. It confuse me.
