Useful instructions

Setup new board and install image files via USB (dfu and ums mode) / U-Boot recovery via DFU

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
Make the STM32MP13xx DHCOR SoM / DHSBC discoverable to other BT devices:
$ hciconfig hci0 piscan
Scan for other discoverable devices:
$ hcitool scan
Scanning ...
When the scan is now performed on a HostPC, the STM32MP13xx DHCOR SoM / DHSBC should be visible:
$ hciconfig hci0 up
$ hcitool scan
Scanning ...
        DC:FE:23:12:34:56       dh-stm32mp13-dhcor-dhsbc
To generate some traffic on the BT UART between SoC and BT chip, try e.g. L2 ping from hostpc:
l2ping DC:FE:23:12:34:56 
        Ping: DC:FE:23:12:34:56 from E8:48:B8:11:22:33 (data size 44) ...
        44 bytes from DC:FE:23:12:34:56 id 0 time 11.44ms
        44 bytes from DC:FE:23:12:34:56 id 1 time 39.83ms
        44 bytes from DC:FE:23:12:34:56 id 2 time 39.25ms ...
An interesting option to l2ping is -f, flood ping, which sends a lot of packets, that means a lot more traffic too:
l2ping -f DC:FE:23:12:34:56

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

Add Device Tree oeverlay to u-boot.
