Raspberry Pi 3 Model B

Article sections

    1. Installation

    1. Choose a free sdcard you would like to install emteria.OS onto. Attention: Please use a card of at least speed class 10 or higher (UHS), since the read/write speed of the sdcard will heavily influence the system speed. Best results are achieved by using cards of type A1 (see public discussion). Some cards are known to not work correctly with the Raspberry Pi; this is a hardware issue we don’t control. Please check this comprehensive list for your specific SD card.
    2. Use the emteria GUI installer for your operating system in order to flash your sdcard. Warning: all data on this sdcard will be lost!
    3. When the installer finishes, take your micro SD-card out of your computer, insert it into your device and power it on. You should see a short text boot sequence followed by the emteria logo animation.

    2. Supported Hardware


    All standard HDMI screens should be supported. Please see the section below for more information about the supported resolutions. The majority of USB-based touch controllers should also work out-of-the box. Following screens have been successfully tested by us with emteria.OS 0.5.x:

    52Pi 5″ touchscreen: The 800×480 capacitive HDMI touchscreen with USB controller for multi-touch.
    Raspberry Pi 7″ touchscreen: The official Raspberry Pi 7″ touch screen display with 10 finger capacitive touch.
    Waveshare 7″ touchscreen: A capacitive HDMI screen with an USB touch controller.
    Waveshare 10.1″ touchscreen: A capacitive HDMI screen with an USB touch controller.


    The audio jack is used as the default audio out. If it doesn’t work in your setup, or if you wish to change the default behavior, please refer to HDMI_FORCE_EDID_AUDIO and HDMI_IGNORE_EDID_AUDIO options as specified by the official documentation. The emteria.OS also has built-in support for USB speaker and USB microphone without additional configuration.


    Built-in support for the Official CSI Camera Module without additional configuration.


    Accessing GPIO is possible just the same way you would do it in Linux (via sysfs). Eg.: https://www.ics.com/blog/gpio-programming-using-sysfs-interface or https://pimylifeup.com/raspberry-pi-gpio/


    Built-in support for ODROID’s USB GPS Module without additional configuration.


    Built-in support for NXP’s USB NFC Dongle without additional configuration.

    3. Custom Screen Resolution

    The emteria.OS is running with many different screens. In the vast majority of cases, it correctly detects the resolution from the connected screen without any changes required (e.g. using the provided EDID information).

    Enforcing custom resolution using “fkms” overlay

    A custom resolution can be enforced by using use vc4-fkms-v3d overlay (instead of vc4-kms-v3d). For doing so, simply mount your sdcard and edit /boot/config.txt file.

    1. Choose the desired resolution in hdmi_cvt line
    2. Replace the overlay name in dtoverlay line.
    3. Save your modifications and boot emteria.OS again.

    Warning: Make sure that the persist.rpi.use-fkms property in Android is set to 1, otherwise the device may not boot.

    Enforcing custom resolution by manual configuration

    Some screen/graphics format combinations do not work with vc4-fkms-v3d. In such cases you can change the used resolution manually, by editing two files (you need to mount both boot and system partitions first):

    /boot/config.txt Old value New value
    hdmi_cvt=1280 720 60 6 0 0 0 hdmi_cvt=1024 600 60 6 0 0 0
    /system/build.prop Old value New value
    persist.rpi.mode.auto=1 persist.rpi.mode.auto=0
    persist.rpi.mode.force=1280×720 persist.rpi.mode.force=1024×600

    4. Installing New Applications

    Additional applications can be installed in same way as on standard Android devices (ADB, Download, F-Droid):

    • Copy your application to a USB drive and connect it to your Pi. Open the File Manager application, navigate to the USB drive and install the application from there.
    • Since Raspberry Pi has no USB OTG, “ADB over Ethernet” should be used instead of standard ADB. Please activate it first in the settings (Settings -> Emteria -> Enable ADB over Ethernet). An example can be found here. New applications can be installed directly from your PC using adb install.
    • You can use preinstalled application market to install new applications. One example for using F-Droid can be found here.
