how do I setup the C-Berry TFT Screen with my Pi 2

Question

How do I setup my C-Berry 5" TFT Screen from Admatec, with my Raspberry Pi 2 Model B? Distro: Raspbian Jessie 2015-11-21

Tried:

wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.46.tar.gz 
tar zxvf bcm2835-1.xx.tar.gz
cd bcm2835-1.xx
./configure
make
sudo make check
sudo make install

Made sure SPI and I2C are off in raspi-config and Tree is on.

wget http://admatec.de/sites/default/files/downloads/C-Berry.tar.gz
tar zxvf C-Berry.tar.gz
cd /C-Berry/SW/tft_test
make
sudo ./tft_test

So, the short answer.... for god's sake look at the connecting cable between screen and TFT add-on card. Blueish color facing down not up.

Full stepvise instruction:

Install latest Raspberian distro (in this case Raspbian Jessie 2015-11-21 - 4.1.13-v7+ #826)

Have all the latest by:

sudo apt-get update
sudo apt-get upgrade

Then download and unpack BCM2835 package:

cd Downloads
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.48.tar.gz
tar zxvf bcm2835-1.48.tar.gz

Adjust the bcm2835.h to RPi2 settings (how I did):

sudo nano bcm2835-1.48/src/bcm2835.h

Change row defining:

#define BCM2835_PERI_BASE               0x20000000

TO:

#define BCM2835_PERI_BASE               0x3F000000

Compile the library:

cd bcm2835-1.48
./configure
make
sudo make check
sudo make install

In order for bcm2835 library SPI to work, you may need to disable the SPI kernel module using:

• sudo raspi-config
• under Advanced Options - enable Device Tree under
• Advanced Options - disable SPI
• Reboot.

Then first run your first try with screen developers software:

cd Download
wget http://admatec.de/sites/default/files/downloads/C-Berry.tar.gz
tar zxvf C-Berry.tar.gz
cd C-Berry/SW/tft_test
make
sudo ./tft_test
