bringing up eclipse environmen(IDE) for AT91RM9200EK board

Hi,

I am newbie to Linux.
 I am in the process of bringing up the ARM-GCC environment (tool
chain)(using eclipse for IDE) in Window platform for use with an Atmel
AT91SAM-ICE and AT91RM9200EK board. I used the pdf proivided in the link
http://www.atmel.com/dyn/resources/prod_documents/doc6310.pdf to set the
eclipse GCC environment for ARM. So now I have the Yagarto tools Eclipse
and Zylin plugin installed as per the procedure. Now I am not able to
find a demo code to begin the work with. I found demo code available in
atmel site but it is only for proprietry software tools like ARM® ADS
1.2 Green Hills 3.6.1 Multi® 2000.
Would anyone be able  to help me with a demo codes(LED blink etc) along
with makefile to start with? and how to proceed about converting the
existing sample coded available for propriety ides to codes which will
can be compiled simple gcc compiler.
I dont have sufficient knowledge about makefiles stuff. I think this
initial help will help me in understanding the environment.

Thanks
