VirtualBox

A customer asked me to create a VirtualBox virtural machine (VM) using Ubuntu 10.04 and containing their SDK. Here are my notes.

Downloads

Installation

Setup storage space

I used an extra hard disk I stuck into my dev machine. I wanted the vm related files to be in /vm 

sudo mkdir /media/fa853c54-d59c-435a-bb09-368a6112ec00/vm
sudo chmod ugo+rwx /media/fa853c54-d59c-435a-bb09-368a6112ec00/vm
sudo ln -s /media/fa853c54-d59c-435a-bb09-368a6112ec00/vm /vm
cd /vm

Install VirtualBox

sudo dpkg -i virtualbox-4.3_4.3.0-89960~Ubuntu~precise_amd64.deb


Create RidgeRun-SDK-Ubuntu 10.04 VM

See instructions at https://www.virtualbox.org/manual/ch01.html#intro-installing

The settings I used: 

mem: 1024MB
virtual hard drive: virtualBox Disk image, dynamic, 100 GB

user: rr
pass: rr

Configure new VM

  • Machine -> General -> Advanced, shard clipboard and drag'n'drop -> bidirectional
  • Network -> Attached to: Bridged Adapter

Configure main development PC as primary source for Open Source package downloads

I have over 1200 packages downloaded due to building various RidgeRun SDKs. Instead of downloading those files again, I enabled apache web server on my dev machine and exposed the ridgerun download directory.

On your dev machine, run: 

sudo apt-get install apache2
ln -s /opt/ridgerun/downloads /var/www/downloads

Configured sudo and ssh

I am a command line type guy, so I just want to ssh into the VM. I also don't want to keep entering the password every time I run sudo.

In the VM, run: 

sudo su -
passwd # root password also set to rr
addgroup root admin
echo '%admin ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers
cat /etc/sudoers
apt-get install openssh-server
exit

While you are on your VM, disable screen lock:

  • System -> Preferences -> Screensaver -> Lock screen -> disable

Update all packages

Although 10.04 is out of support, there were still 243 updates since the ISO was made.

On the dev machine: 

sudo apt-get update
sudo apt-get upgrade

Make a copy of the VM

In case something goes wrong, make a copy of the VM

  • In the VM, halt Ubuntu
  • In Oracle VM VirtualBox Manager, right mouse click on the VM and select clone, give it a name, and make a physical copy.
  • Start the VM again

Install RidgeRun SDK

Follow SDK install steps from https://developer.ridgerun.com/wiki/index.php/RidgeRun_Turrialba_SDK_User_Guide

Setup common download area

sudo chgrp admin /opt 
sudo chmod g+w /opt

mkdir -p /opt/ridgerun/downloads
sudo chmod ugo+rwx /opt/ridgerun/downloads

Use bash instead of dash

sudo rm /bin/sh
sudo ln -s /bin/bash /bin/sh

Close the terminal and open a new one.

Install toolchain

wget http://www.codesourcery.com/sgpp/lite/arm/portal/package4573/public/arm-none-linux-gnueabi/arm-2009q1-203-arm-none-linux-gnueabi.bin
chmod ugo+x arm-2009q1-203-arm-none-linux-gnueabi.bin
./arm-2009q1-203-arm-none-linux-gnueabi.bin # installed to /opt/codesourcery/arm-2009q1

Add packages needed by SDK

sudo apt-get -y install  git-core fakeroot curl build-essential libncurses5-dev texinfo 
sudo apt-get -y install minicom picocom quilt subversion autoconf libcrypt-ssleay-perl 
sudo apt-get -y install ccache uuid-dev liblzo2-dev intltool libusb-1.0-0-dev libexpect-perl 
sudo apt-get -y install libdbus-glib-1-dev libgtk2.0-dev bison flex gperf libbz2-dev

Add github public key

Follow steps at https://help.github.com/articles/generating-ssh-keys 

ssh-keygen -t rsa -C "todd.fischer@ridgerun.com"
cat /home/rr/.ssh/id_rsa.pub

Then go to github.com, log in:

  • settings -> SSH Keys -> click Add SSH key

Install TI DM814x EZSDK

Use default settings. Remember toolchain was installed into /opt/codesourcery/arm-2009q1/bin 

firefox http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html
chmod ugo+x ezsdk_dm814x-evm_5_05_02_00_setuplinux 
./ezsdk_dm814x-evm_5_05_02_00_setuplinux --forcehost --mode console

Add SDK

cd $HOME
mkdir work
cd work
git clone git@github.com:RidgeRun/foo.git rrsdk

Setup local download server

Since I have apache on my dev machine making all the packages I have downloaded available, tell the SDK on the VM to look there first when it is fetching packages: 

export PKG_INTERNAL_URL=http://10.111.0.4/downloads

Build SDK

cd $HOME/work/rrsdk
`make env`
make config
time make
make install

Cleanup VM

Since I am giving this VM to a customer, I don't want to leave the SSH keys in the image. Good time to clean up other files as well. 

rm /opt/images/*
rm  ~/.ssh/*
rm  ~/.ccache
rm -rf ~/ti-dvsdk_dm368-evm_4_02_00_06
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get purge

Additional Ubuntu packages required by RidgeRun SDK

On a fresh Ubuntu 10.04 install (after running apt-get update/upgrade), the installed packages were captured using 

aptitude search .\* | grep ^i | grep -v '^i A ' | awk '{print $2}'

A diff was run on the same output for the VM that successfully build the RidgeRun SDK. The 28 additional packages that were included are:

autoconf
bison
build-essential
ccache
curl
fakeroot
flex
git-core
gperf
intltool
libbz2-dev
libcrypt-ssleay-perl
libdbus-glib-1-dev
libexpect-perl
libgtk2.0-dev
liblzo2-dev
libncurses5-dev
libusb-1.0-0-dev
linux-headers-2.6.32-52
linux-headers-2.6.32-52-generic

minicom
mkpasswd
