How to connect to WiFi network with WPA2 PSK?

Establish connection

$ wpa_passphrase "SSID" > /etc/wpa_supplicant.conf

-> In the next step, please enter the password

$ rfkill unblock all

$ ip link set wlansom0 up

$ wpa_supplicant -B -i wlansom0 -c /etc/wpa_supplicant.conf

$ udhcpc -i wlansom0

Disconnect

$ ip link set wlansom0 down

Simple Bluetooth test

Bring up bluetooth on the STM32MP13xx DHCOR SoM / DHSBC:

$ hciconfig hci0 up

Add support for joy-it RB-TFT3.2V2 SPI display

Add Device Tree oeverlay to u-boot.
