Raspberry Pi - Bad Apple on ili9341 Display

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

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

[RaspPi] Build Raspberry Pi Kernel 3.10 / NEXT for Debian Wheezy / Raspbian with eGalax Touchscreen Support on Ubuntu 12.04

Thu, 12 Sep 2013 19:26:33 +0000

This is about building the latest Kernel / 3.10 for RPi. Bleeding Edge.

Install Kernel on existing RPi SD Card / Raspbian

# mount sdcard in your Ubuntu (I made an folder sdb1 for boot partiton and sdb2 for the root partition)  
cd ~  
mkdir sdb1 sdb2  
mount /dev/sdb1 sdb1  
mount /dev/sdb2 sdb2

# boot partition  
#replace /sdb1/boot/bootcode.bin with rpi_kernel_10/firmware/boot/bootcode.bin  
sudo rm ~/sdb1/bootcode.bin  
cp ~/rpi_kernel_10/firmware/boot/bootcode.bin ~/sdb1/  
#replace /sdb1/boot/kernel.img with the previously created kernel image  
sudo rm ~/sdb1/kernel.img  
cp ~/rpi_kernel_10/tools/mkimage/kernel.img ~/sdb1/  
#replace /sdb1/boot/start.elf with rpi_kernel_10/firmware/boot/start.elf  
sudo rm ~/sdb1/start.elf  
cp ~/rpi_kernel_10/firmware/boot/start.elf ~/sdb1/

# root partition  
#replace /sdb2/lib/firmware with <modules_builded_above_folder>/lib/firmware  
sudo rm -rf ~/sdb2/lib/firmware/  
sudo cp -a ~/rpi_kernel_10/modules/lib/firmware/ ~/sdb2/lib/  
#replace /sdb2/lib/modules with <modules_builded_above_folder>/lib/modules  
sudo rm -rf ~/sdb2/lib/modules/  
sudo cp -a ~/rpi_kernel_10/modules/lib/modules/ ~/sdb2/lib/  
#replace /sdb2/opt/vc with firmware-next/hardfp/opt/vc/  
sudo rm -rf ~/sdb2/opt/vc  
sudo cp -a ~/rpi_kernel_10/firmware/hardfp/opt/vc/ ~/sdb2/opt/

# sync usb mount  
sync

# Unmount sdcard  
cd ~  
umount sdb1  
umount sdb2

Boot Pi and calibrate Touchscreen

This stuff happens on the Pi!

Preperations

sudo apt-get install libx11-dev libxext-dev libxi-dev x11proto-input-dev

Install Tool / xinput_calibrator

cd ~  
wget http://github.com/downloads/tias/xinput_calibrator/xinput_calibrator-0.7.5.tar.gz  
tar -xvzf xinput_calibrator-0.7.5.tar.gz  
cd xinput_calibrator-0.7.5  
./configure  
make  
sudo make install

Calibrate (in Xserver, so open Terminal while beeing in Graphical User Mode)

xinput_calibrator

It will give output like this:
