Install Linux

Can you show me the way to install Linux, and install some application, I
bought mini2140 and I don't know how to develop it.

I added a little step-by-step tutorial on my site for the kernel (sorry,
its only german but you are able to translate it with GTranslate on the
right site into every language):

At first you need a working Cross-Compiler toolchain for your PC. You need
that to be able to compile nearly every system-independend source-code
(like the linux kernel) for the arm9 processor of the mini2440 development
board. Most information you also can find on the internet by searching for
it with different search engines.

I'm also a new beginner of Embedded OS coder. I advise you to follow the
instructions of the mini2140 and read the manual in details then you could
have a brief view about your problem.
