I built a Linux Kernel on the OPTEE site (https://github.com/OP-TEE/build/blob/ma ... cs/rpi3.md) and then flashed it on my microSD.
In the case of wired LAN, it works well, but there are difficulties in setting up wireless LAN.
First, when I run ifconfig, eth0 appears, but wlan0 does not exist.
I do not see wlan0 when I do ifconfig after adding wlan related information to / etc / network / interfaces.
And wpa_supplicant also does not exist. Therefore, commands such as iwconfig and iwlist do not exist.
Of course, wifi works well if you run it with Razbian rather than OPTEE Linux Kernel.
I have no idea what the problem is. Please let me know if anyone knows how.
When the OP writes:I'm confused. You say you are not using Raspbian (I presume you mean Raspbian, or is there a distro called Razbian?), yet you say that the command you are trying don't exist is Raspbian.
what he probably means isFirst, there is no command such as iwlist or iwconfig used in RazBian, and /etc/wpa_supplicant does not exist either.
First, unlike Raspbian, there is no command such as iwlist or iwconfig, and /etc/wpa_supplicant does not exist either.
