Installing Ubuntu
- The instructions below are written for linux. I installed from a Ubuntu live USB drive (Ubuntu 13) on my macbook pro (os x 10.8).
- Once you are booted in ubuntu on your non-beagleboard system, follow instructions here:
- there will probably be missing packages
- you may need to add universe to package repository to get those missing packages:
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse"
- list disks:
diskutil list
Curses
- install python-curses:
opkg install python-curses
