Hobbyist Open Source Satellite Receiver - Raspberry Pi 2???

#Getting the image onto SD
#Method 1, Needs a linux box with card reader

# download http://master.dl.sourceforge.net/pr...te-15.04-desktop-armhf-raspberry-pi-2.img.bz2

# install ddrescue
sudo apt-get install ddrescue

# extract downloaded file
bunzip2 ubuntu-mate-15.04-desktop-armhf-raspberry-pi-2.img.bz2

# write to microSD, mine mounts on /dev/sdb, yours may be different
sudo ddrescue -d -D --force ubuntu-mate-15.04-desktop-armhf-raspberry-pi-2.img /dev/sdb

# now resize the RPi2 image on the microSD using gparted
sudo apt-get install gparted
sudo gparted


#Method 2, Uses a windows machine to write image and RPi2 to expand image:

Use 7zip to extract the ubuntu mate image on a Windows machine.
Use Win32diskimager to write the disk to SD as usual.
Insert the SD card into the Pi and boot the Ubuntu image and go through the setup routine.

Manually resizing the SD card on Raspberry Pi

fdisk /dev/mmcblk0

Then delete partitions with d and create a new with n. You can view the existing table with p.

    p to see the current start of the main partition
    d, 2 to delete the main partition
    n p 2 to create a new primary partition, next you need to enter the start of the old main partition and then the size (enter for complete SD card). The main

partition on the Debian image from 2012-04-19 starts at 157696, but the start of your partition might be different. Check the p output!
    w write the new partition table

Now you need to reboot:

shutdown -r now

After the reboot you need to resize the filesystem on the partition. The resize2fs command will resize your filesystem to the new size from the changed partition

table.

resize2fs /dev/mmcblk0p2

This will take a few minutes, depending on the size and speed of your SD card.

When it is done, you can check the new size with:

df -h

# edit your /boot/config.txt if you want (optional) I add
arm_freq=1000
sdram_freq=500
core_freq=500
over_voltage=2
initial_turbo=30

# Also add any mpeg licences to your config.txt if you've bought them, like mpeg2 (recommended)

# update your repository
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get autoremove
sudo reboot

# if you use nomachine you can get the armv7 deb from https://www.nomachine.com/download/linux&id=1

# Download the RPi2 kernel from https://github.com/raspberrypi/linux/tree/rpi-4.0.y and unzip the download
# I did this in /root

cd linux-rpi-4.0.y

# make menuconfig did not work for us, instead we used the default RPi2 build config

# Download V4L's media_build, I did this in /root
git clone git://linuxtv.org/media_build.git
cd media_build

# cd to the directory above media_build   in my case its root

# Download v4l-updatelee from https://bitbucket.org/updatelee/v4l-updatelee/downloads and unzip the download

wget https://bitbucket.org/updatelee/v4l-updatelee/get/402bf4f7412b.zip
unzip updatelee-v4l-updatelee-402bf4f7412b.zip


# Now create the patch
cd media_build
cd linux
tar xf linux-media.tar.bz2
cd ../../ <--- this should take you to the directory above media_build in my case its root

# Now change this

# Compile and install dvb modules in media_build Directory
./build
make install
cp -R linux/include/uapi/linux/dvb/* /usr/include/linux/dvb/
cd ..   (to directory above media_build, in my case /root)

# There is a bug in one of the qwt headers installed from apt-get, so lets fix that
wget http://svn.code.sf.net/p/qwt/code/branches/qwt-6.1/src/qwt_transform.h
cp qwt_transform.h /usr/include/qwt/qwt_transform.h

# To download the updateDVB source
git clone https://bitbucket.org/updatelee/updatedvb.git

#This will create a directory called updatedvb and will contain the source code.

# open qtcreator
qtcreator -noload Welcome

Then Open a project and browse to the updatedvb directory and
open updateDVB.pro

Go to:
Tools, Options, Build and Run, Compilers

Add Gcc if it is not there, then click apply
Now click on Kits and make it look like this:

http://www.satelliteguys.us/xen/media/kits.129/

Click Apply and OK

# To compile hit the green triangle in the lower left that says 'Build and Run'

Build should run for a little while and updatedvb window will pop up.

Exit out.

Go to one directory above the updatedvb directory.
You should fing a directory named: build-updateDVB-Desktop-Debug

cd into this directory and you will fin the executbl you just compiled called updateDVB.

Now lets get it to your desktop so its handy:

cp updateDVB /home/<your username>/Desktop


Hook up your tuner and double click the updateDVB icon on your desktop.


Go into settings menu and setup lnb, diseqc etc.
