Getting Started with BeagleBoard, with Angstrom distribution

Beagleboard is very small but powerful, with the nice integrated Anstrom distribution, you can turn this little board to a desktop like environment! I followed the beginner guide "HowToGetAngStromRunning" and successfully make it works within 30 minutes!

The good things are that all the drivers are pre-built, so whatever I plugged a USB ethernet, or a USB mouse or keyboard, all works like a charm.

Let's check out some screenshots:



1. Firefox running, I copied my Chinese TTF from my Desktop Linux to it, so it can display Chinese as well.


2. WORD processor & Game.



3. Native ARM development, with the GNU toolchains built-in the distribution, you can work in a complete ARM development environment.
