Raspberry Pi 4

The Raspberry Pi 4 is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video.

Technical Data

  • Broadcom BCM2711 SoC
    • 4x ARM Cortex-A72 CPU @ 1.5GHz.
  • RAM: 1 - 8 GB LPDDR4-2400 SDRAM (depending on model)
  • Gigabit Ethernet
  • WiFi – 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless
  • Bluetooth 5.0, BLE
  • USB: 2x USB 3.0 ports; 2x USB 2.0 ports
  • 40-pin connector

openSUSE in Raspberry Pi 4

Writing a disk image to a USB stick or a SD card

  1. Download the image you want (Leap is stable, Tumbleweed is rolling) from here. Make a choice of desktops:
    JeOS - Just enough Operating System - a very basic system, no graphical desktop
    E20 - Enlightenment desktop
    XFCE - XFCE desktop
    KDE - KDE desktop
    LXQT - LXQT desktop
    X11 - basic X11 system
    JeOS image E20 image XFCE image LXQT image KDE image X11 image

    If the direct links above do not work for you (as we are constantly building new images), please check the general download directory for the images.

  2. As root extract the image onto your SD card (replace sdX with the device name of your SD card).
    WARNING: all previous data on the SD card will be lost. Check first if the device you have selected is really your SD card!
     xzcat [image].raw.xz | dd bs=4M of=/dev/sdX iflag=fullblock oflag=direct status=progress; sync
  3. Insert the SD card with the openSUSE image into your board.
  4. Connect the board to your PC via serial port (optional, but helpful for debugging; USB-TTL serial cable needed).
  5. Connect the board to your monitor (via DVI/HDMI, optional).
  6. Power on the board.
  7. Walk through the first boot steps.
  8. Ethernet is configured to request an IP via DHCP, check your DHCP server for the board IP if used.
  9. Have a lot of fun...
Default login is root:linux, works on serial console, via ssh, GUI.

Known issues

The following features are not working yet:

  • USB hosts
  • Network boot from U-Boot/Grub
  • No sound via jack or HDMI


I don't see kernel output on serial or HDMI

If you don't see kernel output on serial or HDMI, you can try setting the kernel boot parameter to


Beware that if you want to load the kernel directly from the firmware (not via grub or U-Boot) you will need to set gpu_freq=500 in config.txt
