# Commercial Licensed Packages Append to following lines to **conf/local.conf** to include libomxil under a commercial license to your build: ``` # For libomxil LICENSE_FLAGS_WHITELIST = "commercial" IMAGE_INSTALL_append = " libomxil" ``` # Raspberry Pi Touchscreen with Rotation If you have Raspberry Pi official 7" touchscreen connected, you can rotate it with these lines in /etc/xdg/weston/weston.ini ``` root@raspberrypi3:/etc/xdg/weston# cat weston.ini [core] backend=drm-backend.so shell=desktop-shell.so [shell] locking=true # Uncomment below to hide panel #panel-location=none [launcher] icon=/usr/share/weston/terminal.png path=/usr/bin/weston-terminal [launcher] icon=/usr/share/weston/icon_flower.png path=/usr/bin/weston-flower [output] name=DSI-1 transform=270 ``` # Debugging It is possible to debug AGL images on Raspberry Pi using 3.3V USB to serial cable, such as [Olimex USB-Serial-Cable-F](https://www.olimex.com/Products/Components/Cables/USB-Serial-Cable/USB-Serial-Cable-F/), connected to the UART of the board. Follow the instructions below to connect a cable to the board (do it on your own risk, no warranty is provided): * Connect the BLUE wire if you are using Olimex USB-Serial-Cable-F to pin 6 of Raspberry Pi, * Connect the RX line of the cable (GREEN wire if you are using Olimex USB-Serial-Cable-F) to pin 8 (TX line) of Raspberry Pi, * Connect the TX line of the cable (RED wire if you are using Olimex USB-Serial-Cable-F) to pin 10 (RX line) of Raspberry Pi. ![Olimex USB-Serial-Cable-F attached to Raspberry PI 2 for debugging through the serial console](images/RaspberryPi2-ModelB-debug-serial-cable.jpg) * Plug the USB connector of the cable to your computer and use your favorite tool for serial communication, for example on Ubuntu and other Linux distributions you may use screen: ``` sudo screen /dev/ttyUSB0 115200 ``` Pay attention that the colours of the cable may vary depending on the vendor.
