Raspberry Pi

The Raspberry Pi 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.

openSUSE in Raspberry Pi

Writing a disk image to the SD card

Default login is root:linux, works on serial console, via ssh, GUI.

Known Issues with Tumbleweed (upstream)

None.

Tips for Tumbleweed (upstream)

If you do not see any kernel output on serial or HDMI, you can add earlycon=pl011,0x20201000,115200n8 to the kernel command line for troubleshooting (e.g., by editing the GRUB menu item).

Known Issues with Tumbleweed (downstream)

None.

Additional software for Raspberry Pi

Some additional software is available for Raspberry Pi. Some are in openSUSE repositories, others are in Packman repositories.

You should add Essentials and Multimedia repos from Packman, and also devel:ARM:Factory:Contrib:RaspberryPi, if you want to get multimedia software.

Version: Tumbleweed zypper ar -f https://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/RaspberryPi/standard/devel:ARM:Factory:Contrib:RaspberryPi.repo zypper ar -f http://pmbs.links2linux.de:82/Essentials/openSUSE_Factory_ARM/Essentials.repo zypper ar -f http://pmbs.links2linux.de:82/Multimedia/openSUSE_Factory_ARM/Multimedia.repo

Multimedia software

In multimedia software, you may want to install:

omxplayer : a command line media player making use of Raspberry Pi video hardware acceleration

: a command line media player making use of Raspberry Pi video hardware acceleration kodi-noX-raspberry-pi: a media center (without X server and including Raspberry Pi video hardware acceleration)

Misc

Configuring the openSUSE system on the Raspberry Pi

Using the system headless

A headless system does not have a display and a keyboard connected. It is only connected to the network.

Connect to the system using ssh and the login information, user: root password: linux and the IP address the system received from your DHCP server in your network. Use zypper to install the necessary services and applications (the system already contains a link to the repository containing this software). If you are not familiar using config files for services and application, but you are using YaST, you can install a number of YaST modules and use the ncurses interface to YaST to configure your system.

Manual Yast2 Install

# Note: this requires around 150MB free disk space on a freshly new SD. # Yast2 Base: zypper install yast2 # Yast2 YOU base: zypper install yast2-online-update yast2-online-update-configuration yast2-online-update-frontend ncurses libyui-ncurses libyui-ncurses-pkg4 # Yast2 base sysconfig: zypper install yast2-basis patterns-openSUSE-yast2-basis yast2-inetd yast2-network yast2-storage yast2-sysconfig yast2-trans yast2-sudo yast2-sshd yast2-runlevel yast2-pam Yast2 .. some modules. zypper install yast2-instserver yast2-installation yast2-ldap-client yast2-mail yast2-samba-server yast2-samba-client # If you think you miss a Yast2 module, install it ... zypper search yast2 | egrep -v '(debuginfo|debugsource|devel|Quellpaket)' zypper install <module>

In case you want the more familiar YaST2 windows, you have to install an x11 package and a number of yast qt packages

zypper in yast2-x11 yast2-control-center-qt libui-qt-pkg4

yast2

ssh -X root@<IP address RPi>

Have a lot of fun installing and configuring...

SuSEfirewall2

Warning: The openSUSE image does not have a firewall installed by default!

(a number of needed packages are also pulled in) and start YaST usingIn this case you have to make the ssh connection usingIt may take up to 60 seconds before you get the YaST window on your screen.

To install Firewall and manage it with YaST2, you need to install Yast2 and iptables:

zypper install yast2-firewall iptables SuSEfirewall2

Resizing openSUSE RPi SD card using YaST2

To increase the size of the root filesystem itself:

It is not possible to resize a mounted filesystem, but without a mounted root you can't use any programs. So you will need a second computer to perform the following.

Warning: Potential for data loss!

If you have data on the SD card, make a backup & verify it!

Poweroff the RPi and take the SD card to a second machine.

Resize / Partition actions with Yast2:

(See docu http://de.opensuse.org/YaST_Module_Partitionierer) - In German Comment: * The article translates nicely with Google Translate, eg the following German to English, and is easily reset to support many other languages * The article is very old, and supports MBR only which is likely sufficient for most cases

https://translate.google.com/translate?sl=de&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=https%3A%2F%2Fde.opensuse.org%2FYaST_Module_Partitionierer&edit-text=&act=url



Yast2 -> menu : System -> menu : Partitioner -> Menu -> Partition: /dev/mmcblk0p3 <return> -> menu : "Resize..." menu : "Custom Size ", enter the size you want for the root FS, at least 2 G should be used. Edit the size to what you like ... i.e. 10GB Save & run it ("Finish").

errors can be ignored, just force it, say yes at questions

Install the SD card and boot your RPi.

Login as root.

Run this command - may not be necessary for all builds.

resize2fs /dev/mmclk0p2

(see http://linux.die.net/man/8/resize2fs)

Configure Boot & System startup parameters /boot/config.txt

Warning: You may need to adjust some parameters in the file config.txt (see You may need to adjust some parameters in the file config.txt (see openSUSE:Raspberry_Pi#Custom_configuration:_config.txt ) in the DOS partition to have a proper display on your screen.

Using a keyboard

Warning: As default you will get an American keyboard layout. Keep this in mind, when entering the password ...

Manual way of updating keyboard:

zypper install vim vi /etc/sysconfig/keyboard

Change to e.g. (sample for standard german 105 keytype´s):

KEYTABLE="de-latin1-nodeadkeys"

reboot your Pi after changes.

Configure default system runlevel for headless

with Opensuse after 12.3 for RPi systemd are the default, no sys5 init system anymore :-)

How do I change the runlevel? systemd has the concept of targets which is a more flexible replacement for runlevels in sysvinit.

Run level 3 is emulated by multi-user.target. Run level 5 is emulated by graphical.target. runlevel3.target is a symbolic link to multi-user.target and runlevel5.target is a symbolic link to graphical.target.

You can switch to ‘runlevel 3′ by running

systemctl isolate multi-user.target (or) systemctl isolate runlevel3.target

You can switch to ‘runlevel 5′ by running

systemctl isolate graphical.target (or) systemctl isolate runlevel5.target





To set runlevel 5 and 3 we should modify a symbolic link to point a specific Target symbolic link metric:

(runlevel 5) : rm /etc/systemd/system/default.target ln -sf /usr/lib/systemd/system/graphical.target /etc/systemd/system/default.target

(runlevel 3) : rm /etc/systemd/system/default.target ln -sf /usr/lib/systemd/system/multi-user.target /etc/systemd/system/default.target

Manual Network Setup for Static IP

Steps to Setup Static Network on Factory OpenSuSE Image below

Assume your network is an Class C 192.168.1.x with Router/gateway/dns a at .1 and your local domain called "local"



echo "default 192.168.1.1 - -" >/etc/sysconfig/network/routes cp -p /etc/sysconfig/network/ifcfg-eth0_orig cat << EOF >/etc/sysconfig/network/ifcfg-eth0 STARTMODE='auto' BOOTPROTO='static' BROADCAST='192.168.1.255' ETHTOOL_OPTIONS='' IPADDR='192.168.1.20/24' MTU='' NAME='eth0' NETWORK='192.168.1.0' REMOTE_IPADDR='' USERCONTROL='no' # EOF cp -p /etc/resolv.conf /etc/resolv.conf.orig cat << EOF >/etc/resolv.conf nameserver 192.168.1.1 domain local search local # EOF For permanent DNS / NTP settings edit the /etc/sysconfig/network/config settings instead of /etc/resolv.conf & /etc/ntp.conf upon your own needs. NETCONFIG_DNS_STATIC_SERVERS NETCONFIG_DNS_STATIC_SEARCHLIST NETCONFIG_DNS_RESOLVER_OPTIONS NETCONFIG_NTP_STATIC_SERVERS echo "192.168.1.20 MyPIHostname.local MyPIHostname >>/etc/hosts echo MyPIHostname >/etc/HOSTNAME

and do:

rcnetwork reload rcntp reload "

Disable IPV6

Steps for disabling ipv6:

echo "net.ipv6.conf.all.disable_ipv6=1" >/etc/sysctl.d/disableipv6.conf The non-systemd way (typically for 12.2 and earlier) Code: sysctl -p The systemd way (12.3 and later although the above should still work indefinitely) Code: systemctl restart systemd-sysctl.service

Disable LINKLOCAL / Zeroconf / 169.254.0.0/16 on headless

The link-local (169.254.0.0/16) zero conf network may not always required - i.e., at headless to disable it do the following steps:

Change "NOZEROCONF" to yes.

vi /etc/sysconfig/network/config NOZEROCONF="yes"

save it exec : rcnetwork restart

openSUSE self kernel compile

For some RPi kernels available the source and running kernel do not match due to the automated image build failing. The workaround for this is self compile and install your own kernel.

Steps to do:

First we pick an up to date RPi kernel source from GitHub RPi - the standard kernel sources do not have all patches.

cd /usr/src cat << EOL >git3.11.y-update.sh #!/bin/sh cd /usr/src if [ ! -d SOURCES ]; then mkdir SOURCES fi if [ ! -d GIT ]; then mkdir GIT fi cd GIT if [ -d .git ]; then rm -rf .git rm .gitignore .mailmap fi git init D=2013-12-20 if [ -d rpi-3.11.y. ]; then rm -rf rpi-3.11.y fi cd /usr/src/GIT mkdir rpi-3.11.y git fetch git://github.com/raspberrypi/linux.git rpi-3.11.y:refs/remotes/origin/rpi-3.11.y git checkout origin/rpi-3.11.y mv ./* rpi-3.11.y tar cpfj /usr/src/SOURCES/rpi-3.11.y.tar.bz2 rpi-3.11.y cd /usr/src tar xpfj SOURCES/rpi-3.11.y.tar.bz2 rm linux ln -s rpi-3.11.y linux # EOL

chmod 750 git3.11.y-update.sh nohup git3.11.y-update.sh &

This take 2-4 ...depend on your network speed and SD card , cpu load.

now we build the kernel

cat << EOL >make-linux.sh cd /usr/src/linux kversion=$(make -s kernelrelease) echo $kversion #make distclean clean #make cloneconfig #make oldconfig zcat /proc/config.gz >/boot/config-$kversion ## zcat /proc/config.gz >.config #cp -p /boot/System.map-$kversion /usr/src/linux/System.map touch /usr/src/linux/include/linux/modversions.h nohup make \ CPPFLAGS="-Ofast -mfpu=vfp -march=armv6zk -mtune=arm1176jzf-s" \ CFLAGS="-Ofast -mfpu=vfp -march=armv6zk -mtune=arm1176jzf-s" \ dep zImage modules & # EOL

cd linux make oldconfig cd .. nohup make-linux.sh &

This can take up to 30H ..depend on your and SD card , cpu load. This requires a swapfile configured with at least 512M - I use 1G .

once done, install it:

cd /usr/src cat << EOL >installkernel.sh /bin/sh D=`date +%Y%m%d_%H%M` mkdir /boot.old-$D echo "backing up /boot to /boot.old-$D" cp -p /boot/* /boot.old-$D/ cd /usr/src/linux kversion=$(make -s kernelrelease) echo "Installing selfcompiled $kversion kernel" cp System.map /boot/System.map-$kversion cp System.map /boot/System.map make ARCH=arm modules_install INSTALL_MOD_PATH=/ make ARCH=arm INSTALL_PATH=/boot/ install cp .config /boot/config-$kversion cp ./Module.symvers /boot/symvers-$kversion cp arch/arm/boot/Image /boot/kernel.img echo "You can reboot now rebooting" echo " In case of failures , copy back the backup from /boot.old-$D

with use of an sdcard reader and an Opensuse Live cd within an OS emulator Like vmware Player" echo ""

Reboot after done that. In case of possibly failure - restore old kernel.
