I am studying OPTEE in RPI3. (ref .: https://github.com/OP-TEE/build/blob/ma ... cs/rpi3.md)
In other words, I'm not using Razbian or NOOBS, using another Linux kernel.
I have successfully connected to the Internet in wired LAN, but have been having difficulty activating the wireless LAN.
First, there is no command such as iwlist or iwconfig used in RazBian, and /etc/wpa_supplicant does not exist either.
I do not know what to do to activate the wireless LAN.
Please let me know if you know anyone.
