STEPS FOR OPENCV+ROS on LUBUNTU 13.04:

install lubuntu 13.04 on a 16 GB uSD card.

copy hard kernel folder to /usr/local/lib and odroid-config.sh in /usr/local/sbin folder

change ownership of hard kernel folder and odroid-config using chown chown -R root /usr/local/lib/hardkernelcd /usr/local/sbinchmod 777 odroid-config

go to the folder sbin run sudo odroid-config

now expand the filesystem, enable SSH, change screen resolution if required and reboot

now update your kernel from this link using the following commands. This is necessary for changing the default external video devices channel nos to 0-9, i.e for example your webcam will now take device 0 or 1 instead of 13 or 14. device nos 13/14 will not work in opencv

wget http://builder.mdrjr.net/tools/kernel-update.shchmod +x kernel-update.shsudo ./kernel-update.sh

change sources file to install updates. without this, you will not be able to install ROS. go to /etc/apt/sources.list and replace all archives to old-releases and all ubuntu-ports to ubuntu.

ex.: http://old-releases.ubuntu.com/ubuntu/you will need superuser rights to make changes to this file, so open the file like this : sudo edit sources.list

now run sudo apt-get update

instructions as mentioned on ROS website
