1.) Enable SPI
# remove or comment out the spi blacklist line
sudo nano /etc/modprobe.d/raspi-blacklist.conf

2.) Install
a) FBTFT drivers as loadable modules
sudo REPO_URI=https://github.com/notro/rpi-firmware rpi-update
sudo shutdown -r now

OR

b) FBTFT drivers built into the kernel proper
sudo REPO_URI=https://github.com/notro/rpi-firmware BRANCH=builtin rpi-update
sudo shutdown -r now

3.) Install the frame buffer driver (as root):
apt-get install xserver-xorg-video-fbdev

4.) Configure frame buffer driver:
sudo vi /usr/share/X11/xorg.conf.d/99-fbdev.conf
Section “Device”
Identifier “myfb”
Driver “fbdev”
Option “fbdev” “/dev/fb1″
EndSection

5.) add Autostart:
( the gpios= Pins need to be changed to YOUR specification and connection! )
sudo vi /etc/modules
fbtft_device custom name=tm022hdh26 gpios=reset:25,led:23,dc:24 rotate=90 bgr=1
#on my selfbuild shield
#from usb -> sd card laengs
#fbtft_device custom name=tm022hdh26 gpios=reset:25,led:23,dc:24 rotate=180 bgr=1
#from cinch -> hdmi quer
#fbtft_device custom name=tm022hdh26 gpios=reset:25,led:23,dc:24 rotate=270 bgr=1

6.) add Auto login:
sudo vi /etc/inittab
#1:2345:respawn:/sbin/getty –noclear 38400 tty1
1:2345:respawn:/bin/login -f pi tty1 /dev/tty1 2>&1

7.) add Autostart X:
sudo vi /etc/rc.local
su -l pi -c “env FRAMEBUFFER=/dev/fb1 startx &”

8.) Console at boot
Add kernel argument to file /boot/cmdline.txt
fbcon=map:10

[Security Spotlight] Upgrade OpenSSL to 1.0.1g – Heartbleed Bug – Urgent!

So, thats no joke: OpenSSL broke badly!
Here is the background: http://heartbleed.com/

And as there is no zero-hour-fix for Ubuntu (including 12.04 LTS…), I decided to take chances and overwrite my existing OpenSSL 1.0.1 with the new code. It worked out flawlessly – but your system could *REALLY* break. Thats as dirty as it possibly could get!

wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz
tar -xvzf openssl-1.0.1g.tar.gz
cd openssl-1.0.1g/
./config --prefix=/usr
sudo make
sudo make test
sudo make install
