Raspberry pi Vision processing

• Got all the pieces plugged in
• First off, selected the Raspbian OS distribution at the first NOOB boot prompt. 
• Got no VGA output on the first couple boot cycles, used "Safe mode" (hold shift key during boot) to bring up a shortcut to the settings, where I enabled the 2 lines for VGA.
• In raspi-config, I selected the Enable Camera option, then Boot to Desktop. 
• The desktop comes up with a default resolution of 576x416 - painfully large!
• Used safe-mode editor to alter //boot/config.txt:
disable_overscan=1
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=16
yielding a more comfortable 1024x768 @ 60Hz.  Supported modes can be found here.
• If you don't like the Great Britain keyboard layout, nano /etc/default/keyboard layout to 'us'
• Straighten out the Time Zone with 'sudo dpkg-reconfigure tzdata'
• connecting a RJ45 gives access to the web. If you need a static address, instructions can be found here.
• Then it's time get the latest version of rasbian and set up the compiler and tools.  I followed my own previous notes from January (git and build-essential were already installed)

sudo apt-get update
sudo apt-get install cmake libgtk2.0-dev python-dev libavformat-dev libswscale-dev
This installed 91 new packages for me.
Got the newest OpenCV 2.4.7 and extracted it to opencv-2.4.7.  Terminal:

mkdir Paladins
cd Paladins
mkdir OpenCV
cd OpenCV
cmake ../../opencv-2.4.7
make                   ##    This took about 9 hours to run!!
sudo make install


Then following along with Josh Larson's post on Chief Delphi and pulling his code from github.

In Paladins:

git clone git://github.com/Josh-Larson/CameraBoardAPI

which builds a sub-folder CameraBoardAPI

pi locked up when running sudo apt-get upgrade, which is unfortunate.  It was executing a series of "Remove 'diversion of ...' items, then indicated 'dpkg-divert: error: unable to sync file '/boot/start_x.elf.dpkg-divert.tmp': Input/Output error'.  Completely non-responsive since.  SD card failure? Out of space?  Guess I should go get another card and try from scratch.

What I cannot figure out, is when I insert a working card from my pi, it still won't show any activity at boot.

So, starting over with another 4gb SDHC micro, I installed 2013-09-25-wheezy-raspbian.img (available as a torrent) on that card, and could only get video by plugging into my HDMI TV.  There, I changed the config (as above) to VGA in //boot/config.txt again.  Success!

Now, the sequence is to update Linux first, then do OpenCV!
