Simple "Hello World" project?

I am using CrossWorks for the very first time (30 day trial). I was surprised to find that there isn't a wizard that gives you a simple empty or "Hello World" type application. Instead there is  "combining project" and "staging project" that doesn't seem to have any source code in them. I tried adding a main.cpp file to a project created using these templates, but I couldn't get it to build.

How do I get to the point where I'm building a simple "Hello World" executable?

  Never mind; I figured out I needed to download a "target" Package; that gave me some other project templates to choose.

  However, after doing that, I tried creating a project using an appropriate template for my hardware. This project did not build, even before I made any kind of change to it at all. It had many link errors, all saying "xyz is too large to fit in SRAM memory segment".

  What am I doing wrong there?

  I'd really just like to build one simple Hello World application to run on my Arm9 processor.

  Which ARM9 are you using?

  By way of an example, to build and run the examples for the AT91RM9200-EK :

  1. Click "Tools > Package Manager", right click on the "Atmel AT91RM9200-EK Board Support Package" link and select "Install Selected Packages", click "Next" followed by "Next" to install the support packages for this part.

  2. Click "Tools > Show Installed Packages", then click on the "Atmel AT91RM9200-EK Board Support Package" link followed by the "Atmel AT91RM9200-EK Evaluation Board Samples" link to load the example solution.

  3. Press F5 to build one of the example projects.
